i need a new head gasket for my coz, i was going to just put another grp a one on but ive seen some
cometic reuseable wrc type multilayer foam /steel headgaskets,
now , i can get these in 1.42 mm compressed thickness which apparently will lower my c/r or i can get one in standard thickness, i have a escoz 200 block in my car witha 4wd head and am going greys/t34 etc, is the 1.42mm thick one a good gasket to get and what c/r will it give, i have heard a few have had a prob with cometic but dont know if thats early ones or are they all dodgy?
cheers
carl

 

If i was you i would get a Mountune 4 layer WRC one, but they are pricey at Ł370

 

these are on special, were 300 now 120, so its quite appealing if they are good, you had probs tiff didnt you?

 

Yes i did

Fucked my head and block as the casting on the gasket was fault as Paul from PJ motorsport will agree

 

But lots of people use then and they have been fine.

Your choice

 

what happened with paul etc , you get any compensation?

 

Yer, sorted out some stuff with him and Cometic

 

so, would you recomend pj as that is who have these on offer

 

Strut for the power you have i could make you a one out of a cornflakes box and it would be up to the job..

 

If you are going for a Cometic one, i think sappymike is doing a good deal on them

 

Sorry fen but i couldnt miss a chance like that to take the piss

 

cheers tiff

message for mason

 

anyway, ive got 4bhp more than you

 

Yes but mines just stage 1


your stage 3 is shit "unlucky" and you drive like a girl always wearing a skirt

 

fuckoff, stage one
theres more yellow paint on them greens than on the double yella's outside mine

 

Fen it only made 269 on the rollers if that was on greens like yours i would be well pissed off..

 

i wouldnt use em mate, as you know i used to swear by em but after my last engine build i had one go faulty and take the block and head with it

go WRC or even good old gpA.

Sean.

 

Not saying a word

 

anyone else got any opinions?

 

How do the cometic gaskets damage a head and block??

How do the newer type differ to prevent this??

 

Damo V by installing them incorrectly Its all about lining therings up..ideally they need to be installed with engine out of car!...They later ones are apparently fixed rings???Not sure though as i aint seen one yet..i run the older one obviously installed correctly

Strut brace go for a cometic .57 this should lower the comp by .9

 

ok but what actual damage does it cause...

 

Ask Tiff

No sorry i retract that statement!

 

It put a mark in both my head and my block from where the gasket rings were faulty

Fortunatly Karl managed to strip both down and get it sorted pretty quickly

 

i have fitted a few cometics and had no problems/failiures im also fittibg one to my es cos soon

 

Ah I think I know what you mean "Tiff", the extra ring on the centre layer ay ??cheers mate

 

I have one 'in stock' for when I build my replacement engine, how do I know if I have the faulty design/old one or the newer one.

Phil, surely if you were to use long studs and a cometic it would stay put as you torque the head down? What makes fitting it out of the car so different to when it's in the car.

(I can't believe I'm asking Phil for tuning advice )

 

Ermm, me too - one in stock ready for fitment

 

Yep...now that makes it far easier..i did mine incar cause of Long stud.....i mentioned do it out of car because not everyone agrees with long studding

Now i used std head studs using a coppers ring gasket (seperate fire rings) fitted INCAR twice and both failed!!!!!!..IF i'd gone with DIY it wouldnt of happened as i would have used ARP's BUT i foolishly listed to someone else

 

Anyone ???

But, when you put the head back on, you use two/four locators, isn't that enough for the gasket to stay in place ? How would long studs/arp's make a difference

 

frog if ya talking about switchs one its the newer design as he was gonna buy a wrc one till he got told about the newer version and he bought that instead

 

Frog do many DIYers use the locaters then!!!!...I never did when doin the Grp A's

 

That's the one ginge - I can sleep easy now - thanks.

By locators I mean four old headbolts with the head cut off and a slot at the top.
I've only ever done one h/g on a cossie and used that... Seems to make sense to me as you are about to drop 20kg's worth of head on a cylinder block, usually holding it at arm's length. What chance does the h/g have of staying in place otherwise

 

frog were all friends on here and scot would have told ya if it was the old type

he wont let me have hes rocker cover gasket as hes not sure how well it will be

 

Ginge, I have no doubts he would have, if he had known, or, if we had known to ask him.
I am in no way suggesting he would have waylaid us... and wouldn't hold it against him if it was the old one (as long as he didn't know otherwise)

 

i think mine has the WRC gasket (ask Ryan ) but i dont really wanna see it if u know what i mean

 

ooohh my god..........im caking it now...thats the same head gaskets thats on mine n i got it off paul down pj 2.............scariest thing is my car never ran right since it went on...ran hot all the time.........

tried all sorts 12 sort it but the temp never moved...its on gettin stripped down at the min 2 put a new head gasket on just hope when the head comes off it hasnt done more damged than expected or ill b gettin in touch with paul frm pj as no one told me they were dodgy

 

TBH, he prob didn't know about any possible problems at the time.

Good luck m8, fingers crossed for ya.

 

mines been on for over 2 years , runs high compression, up to 2 bar of boost and als just to heat it up a bit more
