Ok my headgasket seems to be fooked so which headgasket should i go for? I had a group a but thats only lasted a few month.
I've head people saying they use wrc 1's but £375 seems a bit steep or am I just being a tight cunt

 

if you use ANY metal gasket (WRC or Cometic), then you WILL have to have the head and the block face machined so that they are 100% flat.

the fibirous gasket (group a) will help "mask" any imperfections in the head or the block face, but a metal one cannot.

how much boost do you run and are you sure the gasket was fitted correctly the first time, as i ran a standard YBP head gasket for over a year with no problems at all, at 20psi on a T34.

 

Got a WRC one on mine at the minute,they are supposed to be re-useable,would/has anybody re-used them??????

Saw these copper ones on E-Bay,anyone used them:

i'd never reused a gasket.

when its been torqued down it does squash, therefore no matter what gasket it is, it will not be the shape it needs to be.

if you blow a metal gasket, your block or your head has an imperfection on its face.

 

Also depends are you on standard head bolts,if so stick with group a or copper,multi layer more suited to long studs

cheeRS stu

 

Mike I'm peaking 29psi thing is probs hasn't been fitted properly cos the lad who done it turns out to be a fookin cow boy so do you think a group a should do the job?

 

yeah standard headbolts

 

bttt cos i need to order 1 asap

 

ive run 32 psi ona group a with a t34 for nearly a year not advisable but its done it lol

best thing u can do is get it stripped check the block with a proper straight edge and head then use a cometic stu@motorsport developments swears by them

 

buy the way thatts holding 27 psi till the rev limit at 7500

 

I've just realised that I can get a Cometic 1 for £120 so will I need the head checked

 

i got a WRC multi layer on mine and never had any probs.

 

..with all metal gaskets you should use wrc long stud or at the very least a arp stud/nut kit...you require a greater clamp.


My 600bhp lump runs WRC long stud and cometic gasket

My DIY engine runs WRC long stud and WRC gasket (500bhp)

My runaround runs a Grp A and wire rung block (350bhp)


Fuck coopers rings right off

 

yes and a mega clean block checked with a straight edge normally block are very straight but get it checked

 

Well mines only stage 3 don't know what to do now

 

advice given man just check both faces then put a cometic on if its ok

 

cheers jay next question is how will i get it checked a garage is doing it so will they be able to check it or is it a specialist thing

 

they need a total flat edge and feeler gauges will do it corne to corner and straight down the middle but if a garage is doing it they should already no how to lol

 

Cheers Jay

 

Cometic headgakset will be fine. see my sig for my engine spec
