IPP copper headgasket

[evildky]

so I just got a copper headgasket form IPP and it's solid!? currently running a multilayer Nismo and got this one for another build and it's solid!? also comes with a tag that says to apply a thin layer of pipe dope around water and coolant passages, should I just coat the whole thing with copper spray? or try some sort of sealant around the passages? not sure what to think of the solid headgasket, anyone else running a solid headgasket?

Copper gaskets are solid. Why did you switch from the steel to the copper? I ran a copper head gasket for a few years and the thing used water from the get go. The first ten minutes of running, I had water pouring out between the head and block (used copper coat gasket spray). I went to the local machine shop and they recommended Hylomar spray. This worked better, but still ended up using some water. The head gasket later blew, so I switched to steel.

my current engine has the multilayer nismo gasket which I recall as being copper? I really don't remember just that it was multilayered with crush rings around all the passages, which might have some sort of a leak now as I've been informed that when racing when I let off the gas I emit lots of white smoke

 

the new gasket is for a different engine in a differnt car, also an L28ET and I'm hoping to build a fresh 3.0 bottom end this winter

Copper gaskets are generally used in conjuction with O rings and will always leak a little water.I had one years ago on a turbo L series 4 cyl and it worked OK with copper tack on it with O ringed cylinders , but it still leaked a bit of coolant.I ran some Bars all stop leak , the kind that looks like coffee grounds and that helped a bunch.You might try some of this
