Anyone made use of a Copper gasket of 2mm plus to help compression ratio on a over skimmed gx head? Im wondering do they work better, how to seal them properly without o-rings ect.

Thanks

I have a copper head gasket on my motor, its only about 1mm thick though.
It seems to be sealed with some kind of white looking sealant. The motor has been thrashed long and hard, no problems.

good to know, wonder if it was just normal silicone?

Yes it seems to be some kind of silicone.

levey so you didnt put it on i gather, but you say it works fine, and you dont use o-rings?


Thanks for the pic

I have used copper head gaskets in my older cars and have used copper spray.
This stuff is hard to get and the last head gasket replacement I used Hylomar
Spray (I hope spelled that correctly) Its a blue tacky spray and has done the
job well.

Clive as a matter of safty you can use any good metal to metal sealant, coper tack, yamaha bond, hylomar and so on. But there is nothing wrong with a coper gasket.

Why do you want to use a copper one?
My mechanic friend told me you can order a custom thickness one from Payen. He once installed one on a over skimmed BMW engine of 3mm thick. No problems yet.

No Clive I didn't fit it so I know nothing, Sidedraught might know cause the motor originally came from him.

Thanx guys, i know a guy who makes gaskets from either copper or ali. Need a 2mm. Defnately going 2 give it a try.
