So glad to see some engine work being done and finding your knowledge a breath of fresh air, got well into the bucket machining and the old "Pat your head and rub your stomach" work lol, now looking forward to some Cossie rebuilding work
I was going for a flight in a helicopter in the States. I asked the owners wife if she flew a helicopter. She said son, I can't walk down the street and chew gum at the same time!
Cosworth Lee with the magic touch on the valves 😎 Silicone sealant doesn't like oil, a long soak wth Screwfix silicone remover and industrial wipes are good for cleaning off with.
Doing the shim+bucket conversation to old VW 1.8 gti engines i aimed for about 5thou in and 12thou exhaust . Got the most out of the camshaft and lasted around 35k miles before needing reshimming.
"Mullered"? I get the meaning, but where ever did that come from. We dont have that here (USA) and it sounds quite useful. (I've already adopted "knackered".)
It’s derived from Romani Gypsy, “murdered”. East London used to be home to many a Romani Gypsy, quite a few interesting words. I like knackered as well, derived from “knacker” a person who used to slaughter horses. “Mullered” beats “Knackered”for severity, although they do mean different things really.
@@HuntsChrisvalid explanation definately- but recall from my linguistic anthropology days the words were also argued to originate slightly differently. ‘Mullered’ was thought to hail from the East Counties of England - primarily flour producing regions. To ‘mull’ something was to pulverise by grinding ie the flour mill stone. ‘Mullered’ being the complete destruction of something. ‘Knackered’ is by way of agreement, related to the equine industry. But some believe the regional origin of it to come from the Northern Counties of England. A knacker was traditionally employed to remove the danglies from unruly or aggressive Stallions. Hence some people referring to testicles as ‘knackers’ - again a more commonly used term in the North of England than South. But both are valid origins of the words - not disagreeing with you just a different viewpoint lol.
I rebuild the Ford Ecoboost 3 cylinder engine. Silicon is used to seal the front cover and sump. You leave the silicon 24hrs before filling with oil. You will end up with silicon in contact with oil. However I have never seen loose silicon in the sump or oil pump pick up.
I use Dirko HT silicone made by Elring on engines, gearboxes and transmissions that i repair and re build, it never comes off inside an engine unlike bathroom silicone which i have seen used by clowns in engine rebuilds.
Hi Lee. Looking at the escort head the buckets look a bit scored on top. At what point would you consider renewing or perhaps surface grinding the face of the bucket.
Could you check all the clearances first before grinding to check none were to loose? With potential to swap valves around for a tight one? Just in case one has to big a clearance and can't add material 🤔
H i Lee You have probably already answered question before but do you dabble in motorcycle engines. I have a couple engines I am lookig to refresh just to make sure they are ok. Many thanks Guy
Are those lower left buckets okay, their cam faces look distinctly "mullered" (Cosworth-speak?) to me and not smooth . Swapping some valves around might reduce the material needing ground off. Does grinding valve stems back not damage the surface characteristics of the steel and foreshorten their lifespan? If you are getting a lot of work on Cosworths surely the extra expense on new buckets of right clearances is worth the added expense and would generate a lot of serviceable used and varied clearance stock that could also be used.
Can not help but think when i see that Cosworth engine with the silicone and lose bolt on the oil pump etc that anyone buying a rebuilt engine or a car with a rebuilt engine that either they ask for a receipt and check it has been built by professionals like your selves or just buy it and assume it needs rebuilt again. No mater how good a rebuilt engine sounds etc is immaterial unless built correct as it could be actual worse than an old worn engine?
Well I have just learned something.I didnt realise there was such a make up as 5 valves per cylinder.So out of touch.The camshafts must be very complex.
The camshafts are no different from a 2 valve per cylinder cam shaft except they have extra cam lobes, a 20 valve four cylinder with rocker arm set up is a bit more complex looking but its still simple except it is crammed into a smaller space
Yamaha launched a bike with 5 valves per cylinder in about 1984. Aprilia launched an engine with a radial 5 valve head in the early 1990s - 4 valves opened directly with skew ground cams a one by a rocker.
My dead dad is turning in his grave that you don't shut the door and the traffic noise is driving his ears nuts and he's dead. Can't turn it off. Tinnitus is a real thing. but shouldn't be on bloody you tube
500hp with a crack like that through a stud hole? Good luck !!
When you were checking those valve clearances, I was thinking about The Beautiful South song, She's a perfect ten, but she wears a 12 😊
Hi Lee, the sealer you use is called anaerobic sealer. Some Vauxhall and VW engines use this type of sealer

Love the education on the heads,carnt wait for cossie stuff👍
I use locktite 577 all the time, an anaerobic sealer brilliant stuff. Love the cozie video mate
i like your point with the gasket sealer its a bit like to much garlic when cooking it spoils the rest of the work
(Smidgen) technical terminology

I'm glad to see you do valve buckets the same as I do on my race endings.
Top work like always!
Thanks Ian. Great edit. My kind of learning.😊

@@HuntsChris thank you very much for the reply and the information. I appreciate your time and effort.
@@HuntsChris knackered means ready for the knackerman, basically worn out, broken.

This is got to be my favourite ever episode, great work
As instrucional videos go this was damn good, take a bow ✅
Some awesome Cosworth work coming in Lee!! Great video as always!
Tip, Lee put go / no go feeler gauge in opposite ends of the holder I find that much easier
Really enjoyed this vid, I have no clue what your doing but you made it interesting. Well done.
Cheers Lee, every day’s a School day.
Done it yet!! Nice, didn’t know that was how you did the clearances 👌🏻👌🏻

There are different types of silicone. Maybe this one they used the wrong type?
You may not have but its not to say it isn't happening.
I use Dirko HT silicone made by Elring on engines, gearboxes and transmissions that i repair and re build, it never comes off inside an engine unlike bathroom silicone which i have seen used by clowns in engine rebuilds.
Great education 👍👍

Good shout that is, but I think he gave the head a lick, so they should all need something off
H i Lee
You have probably already answered question before but do you dabble in motorcycle engines.

Many thanks

Lee has featured Triumph Twins before. The man is an ex-Superbike racing mechanic.
What is the brand name of the green anaerobic sealant you are using, please?
Hylomar is good for fitting things like that sump. Developed by Rolls Royce.

Please can we have something on the E type engine. Getting bored with Cosworth’s
Have to agree John
Seems to be a good 50% of their work! Good reputation for doing cosworth!
Whats the name of the sealant you use please ?
What ever happened with those two American V8s?
Emulsified - what you meant to say at 9.55
You need to get yourself one of little cameras like the go pro with a head strap, lots of creators do it now
Great vlog cheers

Using rego number for tech data assumes original engine in car, which doesn't work for my car.

Why is the Land Rover engine still sitting there?
It's a recall from bearing supplier. Probably waiting for replacements.
👍
Hand held cams sucks

I couldn't hear it.
Get sound synched with your video.....
SUCH BAD ENGINEERING
