Hi guys, as the title suggests, I want to fit the fresh head this weekend but am unsure if the gasket needs hylomar or similar to be sprayed on the gasket face before installation or does this only apply to copper gaskets?? I've been told by a few people that I don't need hylomar as long as the block and head's surfaces are perfectly flat, which mine are now. I don't intend on using it unless it is actually compulsory(never used it in the past and no problems so far) although this time it's an RB30E+T, not RB30E.

Can't hurt, but may or may not have any gain.

I spray all head gaskets with hylomar with the exception of cometic 3 layer metal gaskets. Only a very light even spray, to heavy and it will do the opposite and be prone to leak.

what kind of gasket is it like said it cant really hurt but if its composite fibre it wont matter

Genuine Nissan OEM Head Gasket

Still haven't put the head on yet...lazy I know but I got some Hylomar today for piece of mind. It's going to be a fun few days of installing all the new parts I bought but looking forward to it I have been advised by more than a few that Hylomar is considered necessary on OEM Nissan Head gaskets especially when they are high comp. + turbo Some original photos have not been recovered yet.

Just buy one of these & be done with it. http://www.aclperformance.com.au/prod_g_proseal.htm
