A lesson from IMA Racing on using this metal gasket or the WRC version.

LONG STUD THE BLOCK.

A metal gasket requires more clamping than the std bolts can do..thus premature blowing or coolant leak.

Remember also if you run a 2wd head the head bolts have small washers and at the very least you have to machine the head to take the later head bolts with the bigger washer creating better clamping....BUT long studding is IMO essential for longevity of these gasket.

Please feel free to disagree even though your wrong

 

..... but why do the top recognised engine builders avoid this gasket like a good dose of galloping knob rot??

 

Cos they know nothing lol

Just listen to what Phil says

Neil.

 

tanks but no thanks

 

All top tuners HAVE to use the proper parts and not copies...obviously.

 

cant wait for stu to hear that one

 

Why Matt

If i was a pro tuner at the top of there game you wouldnt want to use copies cause you have to put a warranty on it!

Obviously WRC is better than the Cometic..BUT dont mean the Cometicwont do its job if installed on the correct spec.

 

Funny that cause turners is using a cometic one with normal bolts

Karl is using a WRC one with normal bolts......done 15k plus now, so u must be correct, after all you got the 700+ bhp engine aint ya

 

what you mean you're not?

 

Dingy....Karl aint got 700plus BHP and he obviously uses the large washers from the 4x4 as said can be used but not as good.

 

Karl aint got 700bhp LOL how do u know :'(

U read on other peoples claims of power on here LOL

540 @ wheels @ 7k mate u work it out, and BHP dont stop climbing till 9k

 

Dingy if he goes above 7k the head gasket will blow IMO

 

It must do mate.

Stick with selling stuff and not trying to be a tuner, next you will be changing your name to Ahmed

 

Dingy i aint trying to be a tuner..i am giving advice from actual building.

Someone who reads alot of books is not as qualified as an actual person who trys it wether successful or not

 

Yeah thats true, but it helps if ya got the fundamental's right to start with

 

Well i beleive my fundamentals are

Where is Karl BTW he would like this thread

 

Oh Phil

Why oh WHY do you do it all the time

 

I think he has

 

But your engine never did anything did it?

Honest question by the way!

 

Well i got cometic Gasket standard head bolts and 480 bhp
engines done 10k miles and i have never had a problem
and far as i know you torque head bolts to the same whether there long studs or not

 

Porkie it soon will be!

Cosworth4388 longs studs are tighter on the middle 6 than the outer 4....if you do them up the same the head will crack!

 

i have a cometic and 35psi peak with std comp on std head bolts and it hasent failed!!!!!!!!!!!!!!!!!!!!!!! around 400bhp

 

Sorry Phil i was out mapping with Karl and his engine revs way past 7k and thats not missing a gear

 

Ok..

it's only 3dr and very early 2wd heads that have small washers, most 2wd heads use the later larger washers.









but I know Ford made yours specially with the small washers to be different...

 

whatever he's got its fookin quick

 

Not sure if you mean me there and if so, what you mean?

 

Oh Phil, BTW, Rich is right

 

Stu..i knowwhat i meant and was in no way a diss to anyone Take it as you saw it cause its not a trick statement!


I have no clue how Matthew Bell took that statement BUT then he is from Derbyshire

 

warriers the lot of you pmsl

 

I'm just having my Cossie engine built with a Cometic, 2wd head and standard bolts, and will be around 24psi stage 3 spec

FFS someone re-assure me its gonna be ok.

 

It will be fine lee

 

Tiff might be able to convince you

 

stu, back in yer pram i aint dissing pal yeah i meant you, i was meaning that you use these mountune copy gaskets and as you are regarded as one of the top cossie tuners i was wondering what phil meant by that as i saw it as a dig at you

 

Mountune Copy?
I believe the Cometic is older actually

As many folk on here know, ive got Cometics running in many engines with no problems whatsoever and ive sold literally HUNDREDS and heard so far of none blowing that ive sold. 2 that ive fitted have failed so far.

1) Yes i prefer the WRC but at its price, many folks cant afford the luxury..

2) Yes some have blown recently and if it looks like they have an age limitation on them it will be noted and the info passed to future customers at decision time.

3) Yes i will use them again.

4) Yes my own car has one fitted and has done 18 not very gentle K...

When alls said and done, we are dealing with a headgasket on a 200bhp per litre engine. Many many years ago F1 engineers developed the Monoblock because they couldnt devise the perfect headgasket either so i dont feel too bad..lol

Maybe all we are dealing with here is a simple headgasket failure, maybe they have an age limitation on the materials.. as yet, no-one knows the real answer but the fact remains that far more engines with them on are fine than have failed.

Time will tell as with everything else and im sure that being PF members, you will read all about the scandal first hand.. roflol

 

Just to add...Cometic have actually made a modification to there new gaskets btw!!!!!

Did you know that Stu?

 

So its a good Gasket... but you are pony at fitting em huh?

You coming up on saturday night mate? Sierra is RUNNING

 

what about this one from mountune any good?
Head gasket - 3 layer Supersteel Ref: C841
This 3 layer gasket was developed as a cheap alternative to the four layer WRC gasket. It features "fire ring technology" which results in increased sealing properties around the cylinder bore. Which allows higher boost levels to be achieved

 

Sure looks that way mate


sat night?
Whats happening? And dont worry about the Sierra halucinations.. they will pass

 

there is nothing wrong with a cometic if fitted correctly as said mine hasent failed yet and i dont expect it to for a few years the main problem is when people fit them dry

 

thats what i meant, im one of the many folk on here you see
