Lee, not car related but swap out that dry powder fire extinguisher for CO2, foam or Firexo. If you let that dry powder off you will be closed for weeks clearing up the mess. Go to a very large field with a small dry powder and let it off, you will see what I mean.
I remember me mate getting a nasty key turn bill, his mum and dad were on holiday and his dad asked him to start up his Scimitar to keep the battery topped off... Well we did that one bitterly cold subzero morning and well it seemed the frozen fibre jockey wheel that sits between the two banks did not like the sub zero temps and came apart after briefly firing off and the minute long series of bangs, crashes, tearing and ripping sounds never heard it in a motor before and the big puddles of oil and coolant and poss transmission fluid as the gearbox was grenaded by this poor Essex V6 tearing itself apart and it was over in a minute... I whispered at me mate "Oh noes what did you do?" so the braver part of valour we had it away on our toes whilst me mate tried ways to tell his dad without him going beswick (which he did a lot for ages)
Always good content. . . even if you think your repeating things. . . . there's so many ways an engine can fail . . .so your not really . . . . see ya next time
Hi Lee , enjoy the channel especially the cosie’s. Having done a few of these engines in my time I have never heard you talk about the cylinder heads going soft. I’ve seen a few cylinder heads scraped because the aluminium has gone soft and you can’t get a good head gasket seal. The head starts to move and bang,another blown motor. It was always excessive boost on an engine that didn’t have the cooling system uprated. Apologies if you’ve already covered this cosie fault. Keep up the good work.
Like below you never need to apologize for talking about or videoing cossie motors, I still dream of having a cossie cut-away in my lounge one day if such a thing is out there.
Thanks for the video, That cozzie motor seems like a dumb idea machining all the strength out of it then trying to hold it together drilling long studs in the bottom to hold the head on. John Deere did the same kind of design on a big 4wd wet sleeve diesel tractor motor. when guys fit a bulldozer blade and up power the head and sumps nearly all that holds the blocks together when they crack internally down the middle . My guess is you need that sleeve with an interference fit to seal the coolant in and try stop it moving around. A wet sleeve tractor would have proper sealing rings that I don't see here, so am i missing something like sealant to keep coolant out of the oil pan ?. Also a bad cozzie sounds like a worn out Fordson Major engine with how the heck was it so wrong when torn down ,that it even started and ran half decent L.O.L. Take care guys .
Chap if you're facing a block that is soo dished out then you re-face it what about the valve's extra will they not be the right angle ??? I'm now to engine build's ........ but wish to learn why or what happens to the valve seat guides and spring etc ...... surely they are still miss aligned.???
Hey Lee. Interested to know, how you tell how much has already been faced off a head or block when you initially strip the thing down. Is there some datum/reference point you measure from?. Cheers
Did Isaac check the compression ratio on the scooby engine prior to dismantling? It's obviously a "built"engine with having 14mm head studs, steel rods, forged pistons , Darton sleeves/closed deck inserts, RCM gaskets etc so probably would of been built for high boost so needs the compression ratio to match the original.
Will the new Cosworth liners need flats machined on the top lip where they meet or are they machined in a way that leaves a gap between each liner? Will it require a different head gasket compared to a standard YB?
Hi I have been around the block a few times and that block looks as though it has been modified for max unreliability with studs open to the cooling system and semi wet liners unsupported from the block deck. I suppose it will have all the same problems as an 1800 rover k series. Sorry I am in no way trying to be disrespectful of your work its what the plonkers want to do that I find disturbing Keep up the good work
The floating (at the top) sleeves will never hold a gasket as well as a thin wall lip sleeve that you normally install. The block doesn't have near the integrity being all gutted out on the deck as the original piece. I'd think another block done as per your usual style would be far superior to what he has.
I imagine a lot of the issues you deal with are from inadequate warming up of the engine and aggressive over revving. That centre main indicates that to me. Maybe you could comment on your perception of that. I always seem to get extreme mileage out of any engines which I see as validation of my strategy and opinion.
Lee; just a polite question, When are you going to complete the workshop upgrade ie the back machine area. I hate to say but still looks like a bit of disorganisation, Suggestion why dont you clean down your large machines - degrease and give them a fresh lick of paint, You could do these one at a time on a weekend!!!!! Keep up the good work.
I don’t watch these videos even though they do keep getting recommended to me. I read the thumbnails and conclude they’ve done something wrong…again. Not a great advert for their business. Is Barum Engines for real?
Never apologize Lee for doing your job. Keep up the good work
Keep up the good work, loving the look of the Cossy block without the liners in
Personally not a cozzie guy, but really interested to see and hear your observations on what you get in, keep it up both of you.
Great informative video..... Especially the insite on where the head studs locate as the block was so open .... Keep up the good content 💪
Really showing your knowledge and expertise here. Might shut up some of the moaners 😂
Some of the moaners will never be quiet!
Until plasti gauge was said and then it's just like what is this backyard builders?
WOW
Its been a long time since i last saw a YB wet liner conversion
Nice to see an old skool engineered Cosworth motor to compare to the more modern stuff.
You’ll never bother me with talking cozzies
Keep it coming. Great to see what the Cossi's can handle & not explode. Great to see how you manage to save them.
Lee, my ocd is kicking in... that "premier" badge on the left-side top cabinet is not square. Please see to it. ;-) Love all your content.

Lee. Sort the white cladding over the doors it’s doing my head in 😊
I wondered why the shop was called Bar'um .. Maybe these guys could all get together and form an all male dance revue, bring the Full Monty back! 🤣
Cheers Lee, I wouldn’t like to rely on that crankcase for anything over 200brake it looks really compromised. All the best for now.

That engine is hammered it's going to cost to fix that one
if a head is warped as much as that one is , won't the cam bearings be out of line too ?.

When a head is warped enough to need skimming, doesn't it cause problems with cam bearing alignment?

Make sure you put it in writing even though the customer has agreed to any increase in price on the cosworth .
So how do you go when the head is bent and you machine it flat? Don’t they break the camshaft when the head is put back on ?
Great video, Lee, Issac. Fancy you have a lot of bots on the channel 😂

How are things going with you Lee. Are you still racing the rc car's

Lee .. Quick fire question . If you were to watch .. WEC or F1 ?
Hard times in the UK but still plenty of money to throw at these money pits.
Only hard for us poor folk
Why don't you make a 3rd channel for the coseworth I used to have a coseworth and it was not a good engine
Several times I have wondered what "plastic aging" was.
Plastiguage-ing
🤦
Not much of a head face left on that block. No wonder gasket joint was failing

Love your work but please, please stop the click bait titles, it cheapens your channel.
That Cosworth must have been running poor -- its warn out.

Don't bother commenting
@@davidgerrard8661 😂
In the real world. Use some stones 600 grit and just grind the block in hand. Put the head on. Same deal. Dont have to use a machine for it.
Love the encyclopaedic banter. AI is no threat in your world
