It is now finally time to pull off the cylinder head. I wanted to buy a new CH but nissan SA seems to think there parts are made out of gold so not going that route. I tried every scrapyard in my area and they only have very dodgy CHs so Im gaving that a miss.

Phoned up a couple of places to get some on copper gaskets and they seem to charge just a tad too much for my wallet. So I figured 2 gaskets will have to do.

Phoned up the boys from master parts and asked for 2 gaskets and the bloke on the other side repleyed by asking if I wanted to lower my compression....he recommends that I use a shim with a gasket between the CH and the shim.

The one thing that I'm a bit conserned about is, the area between the block and the shim, isn't it better to put another gasket between the block and the shim or will it seal good well enough on its own or should I just add some sealent(gasket maker) between the block and shim?

TIA

you get special glue and glue the shim to the block... Hylomar I think its called

thanks Tyrie

Got something similar to it, they didn't have the same brand though, I just hope its just as good.

I doubt simply gluing the shim to the block will work. I vote for two gaskets, but only if the resulting CR is calculated first and deemed acceptable.

I did some reading on that copper spray. It looks like its mostly used by people that use only a copper gaskets with no normal gaskets inbetween but that doesn't really help my situation.

Worse case scenario, I'll have to do it twice which somehow doesn't really bother me...more time alone with my datto

I have glued my head saver shim to the block using VHT copper head gasket cement. No problems thus far. However, it is advised that after the engine has been up to temperature and allowed to cool, (Preferabley overnight) the head will need to be retorqued.
