Metal Head Gasket Installation

[James_03]

Hi guys,

Did a quick search but didn't really find what I was after.

Basically I just want to know peoples opinion on metal head gasket installation, specifically tomei. I am helping a mate out with a 25 build, is it best practice to use hylomar on installation or not?

I was under the impression they have a viton/butal coating which eliminates the need for this, I just make sure both surfaces are clean and good RA, then install. What does everyone else generally do here?

Cheers.

Eitherway will work. But for added safety, you can coat it no worries.

Hylomar or copper sprays are not to be used with multi layer gaskets

No need for anything on the tomeis just check block and head surface if within factory specs slap it on with correct torqing and youll have no problems. Tomei are a great gasket been using them myself.

OK cool cheers guys, I have always installed MLS without coating, just the guy I am helping out seems to think hylomar is required.

Thanks again.

It isnt required but can be used without any ill effects. Done this many times myself with no worries on both new and used tomei, acl, cometic gaskets.
