The team begins disassembling the engine by removing the injectors, fuel rail, and related intake components. They discuss the compact layout and outline the next major teardown steps.
Looks like the inside of a clock or a watch.
These cars were you guys cars were the guys are going somewhere.You probably got a future.Just letting you know.So skinny if it was wearing a striped pajamas you would only see one stripe.Two stripes?One stripe.
But technically there is no formal head gasket.It's compression rings and o-rings.
What the heck are these?
Going to be honest, I wasn't expecting to use these little tiny wrenches so much.Think this is the most I've ever used them.
Very tight.Extra room.
Another symptom.
At least they're like easy to get out and not like stuck in there.You could You could like easily twirl them with two fingers when the fuel rail was bolted down.It's probably like the perfect O-ring for it.
Yeah.
The means.Top two.
Oh, there's a little carbon fiber locator down there for them.
Is it These are those locators he was talking about?
The green one on a piece of aluminum to the bottom.It's a thread oh, which that must go on to.We got the injectors and fuel rail out.Pretty cool, compact and uh it's nice how all the the wiring harness is all nice and neat like this.It all comes out as one piece.But the uh the little O-rings and washers go all over the place when you pull them out.So, we fished all those out and we got them everything accounted for, so
Sweet.
Everything's in order and the injectors come out nice and easy.You don't have to like rip them out.
Do you know what size the injectors are?
I don't.
I'd be curious.
We will by the end of this, but
Yeah.So, what's the next step?
Uh we're going to take some of these manifolds off of the water system and then uh tackle this rear cover on the back.I think it's going to get pretty complicated.
I'm a curious
is all gear driven setup here and um there's all all sorts of idlers and um just from what I've read, I got to get that flywheel off, so let's get after it.
I I
So, where are you at next cuz there's a lot we're looking at here?
Yeah, so um we've got the intake manifold, the uh fuel lines, injectors valve valve covers off.Um and next we're going to come down here uh take this gear set apart here for the water oil pump assembly.And then after that, we're going to drop the oil sump.Oil pan sump, that whole assembly.Then we're going to come to the back here where the rear cover is.Um flywheel rear seal and then the whole gear drive for the cam and and valve train is back here.So, uh then we'll do that.This is something the gear drive.It's quite complex from what I've read.And then we'll take the cams out.Um heads off.Hopefully it gets less complicated.
Okay, but by the time we get the heads off.
All right.So, I don't have a whole lot of information or visual on exactly what's going on up here.Um I believe a lot of this is all gear driven.So, um let's get it apart and figure it out.
They explore the front gear-driven pump assembly and explain how the gears, bearings, and timing-related parts are arranged. The discussion also covers flywheel bolts, rebuild requirements, and a sponsor segment.
I'm excited for this part.Okay.So, there's gears on both of these things.
Are you teasing us still?Oh, look at that.That's sweet.So, that that's what was hanging up there.So, that Well, there's a gear in there.That slides through into that shaft to turn the pump.So, if you did turn this, it would try to turn the It would turn the crank cuz there's a crank right there.Those bolts go through the front cover into the center of the gear and the gear spins on on that on the bearing race on out here.
So, that's essentially just a very robust post.
Yeah.
That's really interesting and the cover's bolted right through the gears.
Oh.Just marking so you have some kind of reference.
Yeah, I I don't I imagine that these gears have to be timed or at least the pumps.Maybe maybe not, but in the event that we're completely lost, maybe this would help.
Or it might not matter at all, I don't know.In the event that they are timed for some reason,
Yeah, at least then
we we can maybe get back to that point.
It looks like the the bearing cage is coated and lapped on the faces.They might not be directional, but um we're going to put them back the same way, so So, the front drive for the water oil pump situation up here, uh we got that apart.Now, the pumps and the sump assembly, aka oil pan, are all kind of integrated as one unit.And So, next thing we're going to do is we're going to take the rear cover off now and disassemble the gear drive for the valve train, the camshafts.Get the camshafts out, take the cylinder heads off, then we'll worry about the the sump assembly here on the bottom.
That makes sense.Can't take that off till the pan's off.
We could
covers.
We could probably take the sump assembly out, but I think it probably makes more sense to just do it this way.Take the rear cut, you know, flywheel rear cover, gear drive, cams, heads.
Cuz this is uh seems like this is a pretty complex unit.two
So, these flywheel bolts are nothing more than a used connecting rod bolt.
So, are you going to use the connecting rod bolts?
Yes, so
So, not in this right now.
Right.So, when we put it back together again, we'll use the rod bolts out of the rods currently in the engine for the flywheel.Once you you torque this into a connecting rod, it's it's considered compromised.So, you can only torque these once for a connecting rod.Apparently, they're okay for the flywheel.That's per the book.
Oh, okay.Now, does that need to be replaced or are those able to be reused?
The flywheels need to be replaced every rebuild per the book.Uh apparently, they have found that they crack almost every single time upon disassembly.Just going to have to replace that.That is a nice-looking rod bolt.
It don't say ARP on it.That's the nicest flywheel bolt I've ever seen in my life.I've never seen that either.See that recess that's cut in there?Or not cut in there, rolled in there.That's interesting.That is fantastic.Speaking of fantastic, cuz this is a fantastic thing right here.Uh something new.I'm really on a health kick, been trying to be on a health kick for quite a long time, is green gummies.Now, the major problem, here's the problem with Groన్స్, okay?These you think that this is going to taste like a vitamin?Unfortunately, it does not.You know why I say unfortunately?Because everybody walks around here and grabs the god darn Groన్స్ out of the bag and eats them.So, I'm watching all my guys grabbing my Groన్స్ eating them because they taste uh pretty tasty.Are they not tasty, Nate?
No, I like them.
They are tasty.So, these are really really good and good for you.So, I'm just reading this up.Now, one only net 9 net grams of carbs.So, I'm pretty carb conscious, sugar, you know, that kind of thing.Whole food group vegetables, whole food fruits, vitamins, minerals, antioxidants, super mushrooms, mm.Good health prebiotics.This is a fantastic thing.I highly recommend them, but control yourself.This is the second pack that I've had today.And uh
Only recommended one pack a day.
Yeah, it's only recommended one pack a day, but they're pretty tasty and sometimes I get hungry.I probably should not eat these vitamins as a snack, but they're pretty god darn good.So, if you want your own Groన్స్ just like me, make sure you use the link.The only way you can do anything here is up to 61% use the link down below.Um I highly recommend it.I'm only telling people of things that I eat, do, use, whether it's the dog food, vitamins, uh it doesn't matter what it is, as long as we use it and I promote it, it means that I eat itand do it.So, make sure you use the link.Get you some Groన్స్.Now, let's watch Joe continue disassembling this super cool Cosworth engine.It's amazing.I'm going to come back in and talk about this a little bit later.
The rear gear drive and camshaft area are opened up, revealing the barrel valve, followers, and oiling passages. They examine how the engine meters air and fuel and how the gear train is supported and timed.
We're going to have a seal protector on the crank, so
PTFE seal.Actually looks like it's in really good shape.
Ooh.Boy, oh boy.Would you look at that?It's a bearing.
Don't drop it.
Oh, it's a bearing.It's a bearing.Huh.Imagine that.
That makes
three of them.
I don't know if they're I they might be attached to the cover.We have C-clip.
Mhm.Well, you said that you pull them back so they can't Unless it's
come off.
It should slide around it, yeah.I was looking at that earlier.It has enough room to come out.
Oh, okay.
Okay.
Ooh, there's a lot of coolness going on.
Is it getting good?
Yeah.
Anticipation's killing you.
It's It's using me.
I think we'll stop here.
Oh, yeah.We'll end the video here.Good.
Like, subscribe, leave a comment.We'll see you next week.
We're joking.
Doesn't look like anything's moved, so that's good.All right.Good.You guys ready?
Ready.
We engineered the stand perfectly.And
just enough room to do that.
That was by design.
Oh my goodness.
Looks like the inside of a clock or a watch, you know.All the gears going on.
Wow.
So, that's what we were feeling there.
This gear.So, it's looking good.
that spins.Holy crap.Do you see that right now?
I guess that's what you need when you're going to spin at 16,500 RPM.
Wowzers.That's pretty freaking cool.
That's insane.
Wow.
Now, this has got this insanely cool barrel valve, okay?And so, this is closing and opening with
throttle position along with the throttle body that's in the front.So,
And they're calibrated.
And they're calibrated.I don't know why the throttle body's in the front.I don't see the point in it, to tell you the truth, but hey, I didn't It's not my deal.But, the uh this is just amazingly good.Super cool.What I wanted to show you is as you're looking down there, there's a couple things.You This is wide open throttle, okay?That is like perfection.That is just the most awesome thing ever, to tell you truth.And as it's closing, it doesn't seem to it blocks off air and it doesn't go anywhere.Which is Which is crazy.But anyways, so it's opening, it's closing right here, closing the port this side and closing it into the throttle body or into the runner right there.All right?Now, as you can see through there, you can look right straight down this runner and look right down into the port.
So, I'm shining a light through the spark plug hole.So, that is just actual chamber.And that is really neat.I mean, that is super cool.Now, let's go to here cuz then we have the injector.Now, this injector That's where the injector shines through.And I'm thinking that Yeah, yeah, as you can see there, it hits the very top of the port right where radius is into the uh valve job.So, that is the highest speed uh area.So, the short turn, so this side of it, the bottom down here, is the short turn side of it.Even on a head like this, it's still a short turn.And god darn, that's really neat.So, it's the short turn and the short turn is on the cylinder wall side of the port.
Mhm.
Instead of the other way around.
Right.
So, the Yeah, the long end of the port or the roof of the port, it sh- it shoots So, as you're looking at it, here's that that injector is shooting fuel right opening.So, this is the highest speed portion of the port of the air and it is shooting right there, not in the chamber.That probably would actually be bad, but right here, which would make it probably atomize and in the highest speed highest speed part of it and have to hit the valve probably and the valve seat.That's really really well thought out.I I'll give you guys my thumb of approval on the There you go.
They did a good job.
Yeah, they did a good job.
These Cosworth guys are going somewhere.
These Cosworth you guys Cosworth their guys are going somewhere.You probably got a future.Just letting you know.Um But yeah, that is like really spectacularly good.
This is still all 25 30 years ago?
Yeah.
Yeah.Yeah, this is a long this is a long time ago.But this is fantastic.I was wrong on this on the on the followers cuz after I said that in first video, I started looking at it going they all have numbers on them.Oh, they're all different Oh, they're all size numbers.So, they're adjusting lash.And that's and it might be a ceramic lever, it might just be a diamond like coating or something like that.Not sure yet.But this follower, you can see it from this side.Here.So, that follower that's right there, they make these in just must be an infinity of different thicknesses.So, they're actually changing that whole little rocker arm follower.
Or there's a shim under the lash cap.
You think Well, why would they make different thicknesses of those?
I don't know if these are different.
have different the There's a different number on each one of them.So, I think there's a different thickness of them.
There's a chart in the book.
There's a chart in the book.So, we're going to continue to figure this out of how this is all going to get, you know, working.But this this thing here with this barrel valve is fascinating to me cuz I don't typically like if you were just like
That's closing you know, this thing's probably the amount of time this car would actually be at 100% wide open throttle.I don't know.
Most of the time.
You think so?
Mhm, most of They're either on or on the brakes.
Mhm.Huh?
It's Andy's so we're
I suppose so.But any type of part throttle thing here is just atrociously bad and you would think that you wouldn't want to have all this air disruption of air hitting here, going in there, going in there.But like I said, if it is just a solely a matter of uh idle and wide open throttle, I could buy that.But that's some that is some precision machine work right there, folks.That's nice.And uh obviously all the gears and all the stuff here, it's
And
It's pretty neat.Now, I will tell you.So.This is not 5,000 horsepower cool.This is 12,000 rpm 750 horsepower 5 6 hour cool.
Out of an engine displacement of 2.65 L.
Yeah.Always keep in mind as it engine engine size increases, efficiency goes down.Period.Okay.The smaller the engine, the more efficient it can be.The bigger the engine, the less efficient can be.You know, the steam you know, great big uh ocean freight liner deals, you know, ocean liners with you know, pistons that are as big as this engine, astronomically inefficient.
Right.
Astronomically inefficient.But uh totally different concept.And how everything is just meticulously driven from plus B water pumps, oil pumps.Uh this is a water pump side.This must be a oil pump side over here.But it is it is really neat.Neat deal.
And these three three gears on the back here are supported by bearings in the rear cover.And they get bolted through here.We cannot rotate these the engine without the rear cover on.These gears are only supported on the block side.These These three.The rest of them are bolted on posts to the engine the cylinder heads.But these three have to be supported on both sides of the axle so to speak.So that the the gear doesn't wobble when you're trying to turn it and bind up the teeth.So if we need to rotate the engine and turn it, we have to put the rear cover back on to do that.
So these gears back here are kind of floating in a sense.
Right now they are.
Well, even when the cover's on like Oh, yeah.Bolted down.They're
Sure.Yeah, and there there's also a spec for all these gears as far as back backlash between the gears but also play this way.And that's something that needs to be set as well.So yeah, they are floating in there.So they do move back and forth just a little bit.
Mhm.Super super cool.
The cam caps and head studs are removed carefully, then the cylinder head comes off. They inspect the unusual O-ring and compression-ring sealing system instead of a conventional head gasket.
Look at those tiny things.
That's interesting.
I had to cut down a socket just to get these out by the way.
So you're taking all the cam caps off?
Yeah.And this camshaft here looks like it's got the least amount of spring pressure everywhere.So it's not necessarily on the base circle on all the valves.it it can't be, that's not possible.So, but having it so it's at least minimized, we can back the caps off equally at the same time and not stress one that's under spring pressure.
Do you feel like you're doing it wrong cuz you can't take pressure off the springs?
It it does feel a little wrong.It kind of feels like I should be putting a dummy cap on each one I remove.But I'm turning each nut, these are on studs by the way.I'm turning each nut 90° at a time or 180° at a time.
Keep it even.
Just trying to back them off all the same at the same time.
Don't want to put an excessive load on one cap over the rest of them, you know.
And what's the reason you have to take both out at the same time?
The uh Well, we wouldn't have to if we took the cam gears off, but I think I want to leave those in place for now.But because of the gears
Oh, I see.You can't rotate it out of the way.
You can't really get one out.They come out as a pair.
So, yeah, they lap the bottom of the washer.
Seen you do that before?
Yeah, that's what I do on main studs and head studs to keep the washer from rotating.
So, that when you torque the nut, the nut is spinning on a stationary washer.
There's your followers.
dowelled locating bolt, hold down bolt Look at those oil veins.
That's pretty cool.
Get this oil vein in here.And then a passageway drilled into the stand.And there's a little itty-bitty jets right there to shoot oil under the followers.I imagine this one probably shoots oil between the top of the follower and the cam lobe.And this one probably shoots oil between the stem tip or the lash cap and the bottom of the follower.That's pretty cool.All this stuff looks brand new.Whatever they got for the coating, the camshaft, the followers, lash caps, they they got it figured out cuz I mean, look at that.Who says you need roller tip rockers anyway?Look at this.
So, we're untorquing the head studs right now.If you notice, the head studs are splayed.They're not parallel.They kind of come up at angles here.Which is really cool.Uh I'm sure it's great for clamping the head down.But, uh we have to remove all the head studs to get the head off, obviously.There's a mark on the bottom of the washer.Really nicely machined nut, though.I don't know if you can see the reflection of the light or not.Cool.And washer.
Mhm.Mhm.
Well, that's interesting.
Neato.It's almost like it kind of it's like a dowel at the top and bottom.That one's covered.I wonder if it goes through an oil passage.
I would say that one does.
Maybe that's why they're like that.It's got to be
So we know the one on the end is dry.
Yeah.Well, the inside ones are soaked.
You ready to take this head off?
I think we're ready.I think we're ready to see what's underneath the cylinder head.
Mhm, what kind of gasket?
No gasket.
An O-ring.
It's O-ringed.
Is that it?
Um, that's interesting.
It doesn't even have like those compression rings that we've seen before.
Well, that O-ring sits down in the block here.
a
And
This is a row.
It has these little
One must be stuck on the head.I don't know.Yeah.We've done that before on the Viper.
We have done this before.I'm sure there's a top and a bottom.They're probably been lapped as well.
Mhm.
Think I'm probably out of number those and
Label top and bottom.
Keep them right.Yeah.But technically there is no formal head gasket.
It's compression rings and o-rings.And the head is flat.Oh, there's more o-rings here.So, yeah, that is pressurized oil going through there around those studs.
With the head off, they discover a badly damaged piston and discuss the engine's short stroke and internal oil/water passages. They decide to flip the engine and focus on removing the integrated sump assembly.
It fell off.
Oh, it's going to fall on the ground.Hold on.Did the magnet gear come out entirely?Perfect.
So, it is hurt.That piston is burnt, right?It's It's starting to burn, but it It is burning.And I guarantee you that ring land's no good.And there's even a little bit of material here on the cylinder wall.Right there next to the exhaust valve pocket.Good time for a rebuild, then.So, and it might even It's probably cracked also, but just as a result of burning.
But, yeah.Actually is hurt.Well, once we get that piston out, it probably didn't look good on the side.So, it was the time to turn this thing upside down and focus on the pan and sump system.Yeah, I don't I don't care if it makes a mess.I don't think there's any wisdom in trying to remove this pan with the engine upright.We're just going to flip it upside down.Cuz I I don't know exactly how far this needs to be disassembled to get it all off.Um because this in itself is a whole whole system.Yeah, it actually does go through the oil pan.So.
There are veins cast into the pan itself that carry water through it.And we got some safety wire.Ooh.Been a minute since I've safety wired anything.
You get to do it again.
Yeah.What's interesting is how amazingly small this engine has become the second that cylinder has been removed.
Yeah, if it weren't for the water and oil pump on the front.
Yeah.
This thing is pretty tiny.
Interesting to see right now cuz I haven't taken all the O-rings off yet, as they lay here right on the deck surface, you can see where there's O-ring around everywhere that there's oil.So, there's a obviously an oil path that that bisects the uh all the head studs.So, all the head stud holes are sealed with an O-ring.And then the whole perimeter of the head itself is sealed with an O-ring.And then around the compression rings for the cylinder sleeves is also sealed with an O-ring, which tells me that there's oil coming through all these holes and the coolant passing between the block and the head, I would assumethat there'd be a constant film of coolant between the head and the block in the areas between the the O-ring board.
Since there's no head gasket to actually seal each individual opening.
exactly.And I I wonder if that's intentional, if there's wisdom behind having water in between that the head in the block or if that's just the way it it works.But nevertheless, it's interesting.I'm just curious, you know, I know I don't remember exactly the figure stroke figure, but that's bottom dead center right there.That's not even 2 in of stroke.of stroke.So So you keep the piston speed down at 16,000 RPM.And obviously, it's a flat plane crank as you can see the way the pistons move.
It's too bad we have to have the cover on.So that we can't see all the gears move like they
do.I know.Well, if we get a hold of the timing cover
the jig.It's a rear gear jig that actually supports and holds those gears in place.So because you have to be able to turn the engine over to to degree the camshafts.And you can't do it with the rear cover on.So there actually is a jig that bolts onto the back of the engine.So when it comes time to put it back together, we'll be able to do that.
Roughly 360/20.
by twoYou get to your 2.65.
What do you think, Dewey?What's your problem?What's your problem, dog?
Dewey cam
Ooh, Dewey cam.Oh, all right.
You what?No more Dewey cam.All right, so you're putting this gear back on so that you can take this gear off.Yes, and hopefully the way this is going to work is going to take that bolt off, pull this gear off, and then I can unbolt this pump assembly from here and pull the shaft through the seal and extractit like that and then I can get to the pan bolts on this side.
Right, cuz the gear housing is part of the block.
Yes, exactly.
The team works through the confusing lower assembly, using a jack screw to free the pan and uncover the integrated structure beneath. They realize the sump, main support, and related hardware are all part of one compact system.
I give up, I'm trying.I don't want to do this anymore.Yeah, okay.End of the video, I'll give up.Look at that.Hey, you know, seem sometimes you just got to keep trying and you can overcome anything in life.
Yeah?
Yeah.
Great pull, John.Pretty sure 10 seconds ago you were just saying you give up.
We're going to break this disassembly process up into two more videos after this one.So
So it feels like
Buckle up.Probably could, but ain't got time for that.Wait a minute, how else is Oh, it must not Okay, it doesn't It's not attached to it.What's keeping this from
There we go.
All right, well hopefully I didn't do something I shouldn't have done here.
Uh-oh.
Cuz this is literally the pump we're taking apart.
I was so close to hitting the engine stand.
Okay, that is quite interesting.
a long drive for it.I mean is that the drive splud?
Yeah.So that floats in there.
And it must enter in there.
It looks like you're going to have to take this off.
Yeah, I mean I was so scared of that.
plate.
Like it's just
What's inside here?
Yeah, so that's where our scavengers must be.
Oh, I see.
Something with a fan.
Filter's there.It goes down to the oil pump.
But they both turn on separate gears.So, they turn different speeds.
Well, there we go.
Yeah, a little spline in there.Roller bearing in there for the OD of that shaft to support that.They've really got the whole like supporting the shafts and axles and stuff figured out.
Yeah.Everything's supported inside and outside.
What do you think we should do here?
There you go.
Just
I wonder.
All right.Looks like all the hardware is off.Ready to see what's underneath?
Probably sealed down with some Yama bond or I'm sorry, Cosworth
Cosworth bond?
Cosworth
There's no Honda bond around here.
Cosworth bond.
Yeah.
We got some movement.
It really is.
So there is a jack screw hole in the center of this inner bearing race.And we can't get the pan off and I'm wondering if it has something to do with this bearing race.So we're just using a jack screw to pull
Oh, it is that.Yeah, that makes sense.
Yeah.
We're sitting here.
Mhm.
There's the parting line right in the center.
I bet the pan just comes right off now.
Yep.
Look at that.Using your brain, Joe.Good job.
Sweet.
Oh.
We were looking at it and it looked like right here, this area
Cuz that's
something was going on.
Yeah, that's the only bearing race that has a parting line through the center.
it, yeah.
So that'll do it every time.
There it goes.
Dang.Good call.Oh, yeah.
All right, so do we think that this is a pan that goes over main caps or do we think that the pan is an integrated
I think that
Yeah.
I think it's a integrated everything.I think those are main studs.
Yeah.Well, these are obviously the main studs.I'm just wondering if you think maybe there's nuts under them or if this whole sump is the actual
I think the whole thing's everything now.
I think it is, too.
I don't think we're going to see any main caps.
Yep.
Would you look at that?
Look at that.Oh, those are all those washers?
Yep.Like a motorcycle.
It's so small.That's how short those rods are.
Look at those flywheel bolts, too.
Yeah, they're using flywheel bolts for the rods.That's crazy.Oh, look, they're they're doing that It looks like the acid etching of the numbers there.
This is actually etching.
Yeah.This crank looks killer.The main studs and nuts are torqued from outside the engine.
Yeah.
That's pretty cool.What do we do to get the rods out of it?I don't know if it's a good idea to turn the crankshaft without the main caps.
I wonder if there's dummy caps they make.
Maybe.
No, they're super tall that go on there.
Oh, look, and there's a orange right there to seal it.Looks like Oh, no, no, it's just part of the stud.Never mind.Um yeah, maybe there is some kind of tool that you use with I can't imagine it's it's good to just try to turn
Rotate it, yeah.
Compromised.Rod bolts journals.
Journals.
Those two rod bolts are now officially flywheel bolts.
They remove the crankshaft and inspect the rods, pistons, and cylinder condition in detail. The discussion highlights the tiny stroke, close journal sizes, and the extent of the piston damage.
It's so small.
Wow.Oh, it has three It's got two rings and oil.Yeah.It's got a compression ring and oil scraper and an oil ring.
Wow, that's a really robust little tiny piston.Look how much material is there around the the pin end of the rod.I wonder what the XF piston looks like.That needed more rebuilds.Some kind of interesting coating there.Yeah, it looks like the same on the pistons.Yeah.Yeah.Those valves are getting very, very close.
They're probably supposed to, butthat's really close.It's an interesting thick oil squirty situation going on.It's like oil squirters.Yeah.And it So, apparently it's okay to rotate with the cap off.I've I've made a decision that it's okay to do this.Executive decision.I mean, it it rolls really nice.Yeah, it looks like it.I guess I was worried that the ring tension would try to push the crankshaft up in the air, but it's doing all right.It's such little ring tension in this thing.That That's probably pulled to 60 70 lbs.
It's insane looking bolt.I don't know what they look like, but Yeah, they look like flywheel bolts.What are you doing?That's all right.
How bad is it?
It's real bad.
Real bad.
It's real bad.
It's
Uh it's not good.So that that's This is what you saw from the top when the piston was in, obviously, but you can tell
Oh, yeah.
She's burnt pretty good.Ring stuck in it.Well, second ring isn't, but top ring is definitely welded in there, is stuck.She was probably smoking and low on compression.
Not having a good time.
It doesn't look like it did too much damage to the to the the liner.We might be able to fix that.Worst case, we just have to replace that that sleeve.We'll pull this crank out real quick.Interesting about the crankshaft, rod pins look really close in diameter to the mains.
They're really close.It's hard to tell the difference.
Should you measure it real quick?
Looks like they bolt heavy metal into the crank, if that's what I'm seeing there.For balancing?
It's like you're playing Operation.
Yeah.
We did it.
Yeah.
Good job, Nate.
I didn't do anything.Good job, Joe.The squirters look cool in there.
So here it is.The final layout of an XFE Cosworth 2.65
2.65 in there.
It's cool.
And you can imagine we probably fill up one more of these cars after just assembling the cylinder heads with the barrel balance holes.
I'll spray everything in there.
Well, yeah.
So, what size are these journals?
Yeah, cuz it's interesting when you look at the crank, which is billet, by the way.No surprise there, but the rod pins actually look the same size, maybe even larger than the mains.
Really good overlap, too.
Yeah, that is outstanding.Right.Stout little crankshaft right there.
I just a rough idea, 1653.That might be a Yeah.Is that a Honda pin?I I can't remember off top.
What was that?
One 1800 about.
So, just bigger.
So, it is a It is bigger, but unless you're dealing with a motorcycle, you rarely see the rod and main journal be that close in size.
Mhm.That is crazy looking.Still a little bit of material up top.
It's always hard to see this stuff on the camera.
sticking through there.What is that?Oh.
For that.
That post.
What?
Yeah, it's kind of weird.You see how shallow the sleeves are?I mean, obviously that they don't need to be deep, cuz it's short stroke.Not even 2 in of stroke.But
Yeah, it's scuffed.There's a little bit of material there.We might be able to fix that.
Well, Cody do his magic.
Yeah.
Or you.Or the ball hone like the manual says.
the manual tells you to just ball hone it.Which is very interesting.And you would think of all things for uh
Look how precise everything is.
Yeah, you would think that the RA and ZK and what whatever, you know.
They said, "Nah, don't matter."
Although the the current hone finish looks really nice.That doesn't look ball hone to me.That looks like very very precise and nicely done.
There's no way that's ball honed.That's definitely done with a machine.That was a long process, but I think we learned a thing or two.
The video closes with reflections on the engine's precision, the unusual parts, and comparisons to other high-performance engines. They end by asking viewers to identify some remaining mystery components.
I think so.Is that it for tonight?
I think we're calling it a night.
All right, we'll be back in the morning to show it off to Steve.
All right, so Joe is on his way down to MKR because we need some parts.So, he's going to take some video and some stuff down there of the cars storage room full of engines and parts and all the cool stuff.I mean, maybe look.So, I I'm looking over the parts.Here's those little super cool rocker arms I was talking about.It is insane.So god darn cool.And then I really love this little crankshaft.And I think we figured out this has a stroke of like 1.900 so less than 2-in stroke.Less than a 2-in stroke.And flat plane.Whoop.So skinny if it was wearing a striped pajamas, you only see one stripe.Two stripes, one stripe.And I thought you'd find this really interesting.Let's compare this to what our normal engines are.Now, this here, this is 3,500 plus horsepower SML crankshaft.
All right.This is your typical5,000 plus horsepower.I say plus because this is actually the same crankshaft that basically the same crankshaft as you'd use in a nitro methane car.So, however many passes they get on a nitro car, I don't know.5 6 7 8 9 10 passes total on a crankshaft.But, Pro Mod crankshaft, Cosworth crankshaft.Isn't that cute?
It's amazing.And whatever they have going on in here, uh something that is spinning 12,000 RPM and has actually has things bolted all over the place.I would say for balance slash there might be some harmonic dampening going on here is actually what I think that might be, maybe.I'm not real sure.I'm pretty I'm really interested to see.But anyways, this thing is super sick, cool.5,000?750.
Uh ironically enough, 10,000 RPM.Mhm.It will.Just Just got done running mine at 9,200 pretty regular.Tom runs his at 9,500 all the time.Um they'll go 10,000.Uh I like to swing this thing 10,000 compared to this thing at 12.That's pretty amazing.Bunch more information coming on to this thing.So, remember like, subscribe, leave your comment and if you know if you know did Joe talk about this if ask if people knew what this was what these are.
Oh, no.I'm curious myself.
What are these?There is something bolted in there.What are these?I'm thinking that they're some type of happening.Is what I'm figuring.Let me know what you think.Anyways, I'm Steve Morris.Have a great day.
