gasket sealer

[tevan]

I am putting rings in my 80 and was wandering when I put this back together should I put gasket sealer on all the gaskets? O r should I just put my new gaskets on dry? Head gasket too? thanks in advance

Pretty much the rule is install new gaskets dry. Exceptions are noted in the service manual.

That is what I was reading in the book. I just wanted to touch base with some of you guys that have actually done the work.. thanks

I have sprayed head gaskets with a copper spray.

I have sprayed head gaskets with a copper spray.

Me too.

What's the benefit of bothering with copper spray?
Thanks

Aris:

Don't really know other than its an old trick from way back when gaskets didn't seal all that well. I've never had any problem with head gaskets, either Honda or aftermarket. Probably doesn't hurt anything, but not necessary.

Well, we old guys are old fashioned and like to use old tricks....

I would be inclined to agree with Mike.
I never felt the need to have to add anything more to these expensive gaskets. And never had a problem
Now don't we all looooove our aerosol cans and looooove giving them magical 'fix it all' qualities they might not possess in the first place?
