Paul, with a glint in his eye “I do like an escort 😊” - quickly corrected to “I do like a mark 2” - classic 😂
Lee a couple of ideas for you on the blown motor. The valve relief pocket in the piston looks very thin on the piston edge. This can lead to overheating especially on the exhaust valve because there is a large area to absorb heat that can only be conducted away to the crown through a thin area. If the valve pocket cant be made smaller then think about trimming the outside edge of the pocket lower. A little less compression but it will run a lot cooler. I also saw your comment on the rods not staying centered in the piston on the pin end. One way to address this is to make a teflon button for each end of the pin that rides in the pin and has about 5 thousands clearance to the cylinder wall. They will be light. You wont need the pin cir-clips and the pin/piston wont rock. Just a thought.
The "Flame Path " of the exhaust gasses can be an issue, from 50 + years in Motorsport, thin piston crowns can be cut away, if the gasses have an obstruction in the way
I was thinking exactly the same thing; those edges look "born to glow" and cause pre-ignition/detonation problems, as indeed they have. Agree with the suggested solution too.
Hello from one of the performance centers of the USA, North Carolina. That overheated BMW engine proves that idiocy is not limited to race, creed, or country of origin, yup drive it till it dies 😀 Good job on the S54, reputation is job #1, also it is easy to buy race engine parts ready to go out of the box, but to make stock parts work, that takes time and dedication, I salute you 👋

It's how a business deals with a problem.with a customer when a problem arises shows how honest and fair that business is
That's very kind of you to help him out and sponsor him. You will be rewarded with not only advertising but hopefully a load more work because of that. Great video!
They are not sponsoring them, more like giving his mate a hand by building the engine at mates rates to help out monetary wise.
That’s how I understood it.
@@michaelslee4336 He even described it as "sort of sponsoring him" and I'd certainly consider it as a type of sponsoring. A sponsor doesn't do or pay for everything as a rule, that's why you see numerous brand names plastered on race machines. Most only cover either certain parts or to a certain dollar amount, Barum are sponsoring him the labor and some parts, that IS sponsoring him.
@@lorditsprobingtime6668
Read the original comment, the dude is describing a traditional sponsor by talking about being rewarded from the advertising.
Helping out a friend with no return expected is not your traditional sponsoring.
@@michaelslee4336 I'd bet he'll have a BARUM ENGINES sticker either on his car, trailer or gear somewhere, aka, sponsored.
@LORD, IT'S PROBING TIME 666 Thank you for your support mate! You got what I meant.
Well done for standing over the E46 problem engine and helping with the guys racing facture😊
Great ethics and business acumen. I always keep accurate time sheets on projects like this. I have a separate line item on my P&L spreadsheet. It gives me an accurate accounting of "good will" or sponsored labor. You may want to track your labor for these projects accordingly. Always great to see the Barum Team. I just finished up the top end of a motor this morning. A great way to start the week. Be good. Stay safe. Wishing you a Deluxe week!
You're a top man Lee
Very kind to help a mate out
Tommy G junior is different gravy
Seen him a few times and absolutely smashed it !
Fantastic of you to help out
Absolutely love the channel
Thanks
Lee, in my opinion I think you dis the right thing, and that's my experience of old school Dave P, it is a science, however when pushing things to the edge of the envelope, stuff happens, but if both parties are acting in an honest and reasonable way, then that's what can be achieved. When I started with Dave I said to him I will never lie to him, and i never did, and near the end of my ten years of racing he put heat tell tales in some of his engines, so he probably knew that I was honest .
Sir I rate you very highly. Keep doing what you and your team are doing and choose your customers well. Best Regards Colin (Ohio)
Ye I agree it's one of those things but seeing as it's the 2 pistons that's broke the jets it's most likely that that's caused the melted pistons
Woosner pistons in a dirt bike are awful so probably the same for car pistons
Good that he is a mate and understanding of the situation and good luck to his son on bikes I raced a few years around the tracks of Ireland north and south
That pretty much slaps all the trolls who were blaming you regarding the Beemer round the head with a dead fish.
Good on you.
Your a very genuine good company. Proud to be British.
Your a good man, and I respect that! Good way dealing with the bimmer engine. Many others would have told no warranty as you race it. But friends are special in that respect too, you’ll go the extra mile.
You guys are awesome helping your mate out and sponsoring the boy out
THIS IS THE CORRECTED Comment

You have a great attitude to your work amd customers , you deserve success !!! . Well done !!.
You don’t need alignment tools for clutches, sockets extension bars an insulation tape. Or just feel that the friction plate is central to the pressure plate with your fingers
Done loads like that..👍👍...also sometimes I've used the Mk 1 eyeball...👍👍
@@richardmessenger9474 always worked for me. The good old mk2 eyeball is usually right
BMW M20 legendary engine cant wait to see what you do with that 🤗
Try gas porting the top ring land meaning drill a bunch of holes down from the top of the piston to right behind the top of the ring about halfway down the Groove width.
I used to take small block Chevy TRW pistons and put another ring groove between the top ring and the top of the piston. Drill a bunch of holes down behind it just don't get the thing lean.
Nothing wrong with kicking in and helping sponsor racing efforts.. Just need to get a Barum Engines sticker or two on the car and maybe the boy's bike.. I really am all for helping people out by donating labor and or parts but because I want to do it, not because I'm forced by someone trying to scam me.
I'd say the jets on BMW engine moved where piston twisted an clipped the jet making it touch the side of the rod
Great ur doing all u can to help out customer
Would like u to machine sum bit foe my rs turbo one day
An owner of a engineer building company I know had the same thing happen to V8 that had a engine block delivered to them so they could do the head on this engine. the block was done by another engine builder, when they installed the engine in the car and run it on the dyno they loss oil pressure at idle but had pressure on high rpm. They took the sump off to find that the oilers had been knocked off and were in the sump looking like ball bearings. Where the piston has blown out may be caused by the edge been to thin and having a sharp edge. Radius the edge of the cut as this will help stop it from developing a hot spot, as like when you want to gas cut heavy plate in from the edge you centre punch and the edge that is burred up will heats up faster allowing you to pears the plate.
M20 engine, I think I can see a crack from the water jacket to the chamber on No.1, and those heads crack through the cam bearings under the cam, worth a good look!
Was just thinking what someone said further down about maybe would been best to keep the mates arrangement between you guys …. In case others decide it’s a precedent and try to squeeze out their own sweet deals out of you.
It’s a fair point actually and goes to show how perilous being in business actually is nowadays - it’s really really difficult finding anyone anywhere that wants to be 100% honest about errors with their work or even the suggestion of it, and a sad thing that when you do the danger is the honesty is taken advantage of and people then try to screw someone over. Personally I’m not nor ever could be like that and if a person has the decency to admit fault, it makes me have all the more confidence in their abilities going forward. But that just me and it’s a shame it’s not the outlook of more people instead of viewing it as weakness and opportunity to do someone over.
What your doing for your friend and by supporting his lad is full bore old school decency. Good on you both for the clear mutual understanding - superb!
Thanks for another great post
Good video mate Tommy G is a good guy and his boy is a talent, good luck though he does know how to wreck a machine, back in the day when he was racing bikes I did some spannering for him, he kept me busy
I would not want to go without oil cooling jets.
It has been said that the Nissan 300ZX was able to tolerate people cranking up boost because it had oil cooling jets.
I have heard that JE warns everyone that this can happen with their "FSR" pistons. The FSR design lowers weight and friction, but it isn't without problems.
think the same too oil jets very important. h beams leave very little space for jets to work with. small end travel can cause it to on geardown. design flaw 100%
I understand you helping out a mate, however, be careful that you don’t open the floodgates for other people trying to get warranty on a race engine!
Nice one Lee hope you guys sort it another good video cheers
All good for the beemer technical 'except'--I would not be mentioning that you are covering the work. That is more of a personal/commercial undertaking and is not relevent to the engine as found. Now you have said this, lots of other spivs (and you know UK is full of them because you have dealt with some already) are going to try and get cheap work done with their sob story because this indicates you are amenable to doing it now. Keep the personal financial arrangements out of these videos to protect yourself.
Many thanks!
01:45 - Boots!
I am partial to some Dunlop CR65's Birmingham myself, 5.00 x 10 inches, but that is me. Zoom! (with a bit of left foot braking) 😎
Ha, bugger, hadn't realised it was Tommy G's M3. Fair play for supporting Johnny though. He didn't just win the talent cup though, he absolutely dominated it. I'm hoping he get the chances his obvious talent warrants.
Lack of oil cooling in the cylinder with that broken oil sprayer are probably related to the wonky piston.
High lee I really look forward to each one of your videos always entertaining also I have seen damage like that on pistons where the sharp edges on top of get so hot that they glow red hot and this causes detonation worth looking into .
Aluminum alloys do not glow red hot ! pre ignition and detonation, usually center around combustion pressures and cylinder heats, running too high a static pressure ratio leads to the tuner retarding the ignition timing and this causes delayed cyl burn and high exhaust valve temps, and it is all down hill from there
Need to pull my finger out and get on track with you guys too
nice gesture
The BMW head has been cooked before and is probably soft . How was it's hardness reading ?
Good Show
What do you think about roller rocker kits in cross flow 1600 ford similar spec to the motor you are talking about in this video
You such a good sport
Well done.
Criky guys, you are talking track days. Friday morning was -35°C. We still get snow into April and get snow on our May long weekend, about the 21st.
Gidday Lee,so ya moving in to GP bike racing.{should have kept the CBR]Today support for a mates son who, tomorrow is in Moto GP?.Good on ya.With the BM,the oil jet must make a difference, BM put them there and you do the same.Why the rod clearance has touched or is that a oil stain on 3&4 only you could tell.Maybe oil pressure has spun them as the rod has pretty flat surface's and as you said located very close.So there could be a reaction from a spinning rod with high oil pressure and the angle of the dangle. You know what its like, strange things happen.Its why R&D exists.
Well spotted No. 4 rocker clearance way out of wack ,eagle eye.😵💫
That's why BMW designer's put a certain type piston in
well done Lee top man!
I really don’t think the oil jets or engine build had anything to do with the problem, I would say it was not properly turned,example air/fuel and timing at different rpm and loads, should have a good tuner setup on a dyno.
Thinking and by the way the channels heading, I may have an idea, how about a technical channel showing all the repairs in this video and keep this for all the round up just like this one,
Urrgggh a mk 2 escort? Nope sorry has to be the mk1 ….well from looks at least. 1st car I drove after passing my test and belonged to a mate who used to lend it me very often as I was cash strapped and couldn’t afford my own motor. Even added me to his insurance. Good memories and type of friend you just don’t seem to see with others now.
Once you alter an engine from the original manufacturers specifications all warranties are null and void. If the oil jets are a factory fit clearly them pistons are not. Ultimately it's your business and your profits , you do what you think is right for you.
Get the hot gun out then, Paul. 02:00 groooovy...
It’s sometimes always better to work with a customer where possible and it could be argued that you are partially culpable for the damage in the oil jets.
I hope he has Barum Engine graphics on his BMW race car
14:00 - just get him to stuff your sticker on his car, free sponsorship.
Yup the preignition could(and likely was) cuased by the jets not being there I would at least eat the labor and likely the parts
The older tread pattern 888s can't be recut as 1 to 2mm deep as it exposes the cords
Pinto is a North American native tribe, but I suppose they could have got to Paraguay, via Germany. Get that BDA, Belt Driven Anglia, of all sorts, the name comes from. I was born in 1962, January... 😎
What does humble pie taste like. ?
There is absolutely nothing wrong with an engine shop helping out a race team essentially in exchange for displaying some stickers instead of exchanging hard currency. 😉
They're the R888R, the original R888 soooo much better in the dry!
I bet the e46 brake booster is leaking and its connected to the intake close to 3&4 cylinders.
Surprised you didn't fit roller rockers .
Stem tips tend to get peened with a high lift cam .
Manipulating a squirter inwards is an artform 😁
That looks like pre ignition damage to the pistons
The top half of the bearing is all shiney in the middle, another bad sign.
Year on races engine and its early detonation piston burnt
Always have to trouble shoot a problem
Did anything become of the American guy that wanted to donate milling machines?
Is the intro engine noise rs1.6 16v
Marginal tune run hard loses a couple of squirters and fails on those cylinders, not all that hard to understand...
10:30 the lifetime warranty the tight old gets love gets into gear
Personally I’d keep this little deal very shhtum or they will all want looking after for nowt after 🤣
tell every one its free beginning middle and end it don't cost any thing and as new viewers let them know also do a title and thumbnail free subscription all this year
CP pistons are the ones i used mate, better webbs in the pistons with room for the oil jets
What are you 'guna' do?
Well, my first advice to you, 'Lee', is to spell a bit better! 😎👍🙃
Bavarian motor works makes a weak engine.
looks like a bad tune , bad fuel , and way too much timing
A belt drive A series engine? Ari Vatanin 1979 in the Works Escort RS1800. I say, suits you sir ooh ooh.
I most certainly will subscribe, but just as soon as when you tell me where your waste is going. Come on boys, I’m on your side.
Well done.
