copper spray gaskets [Merged 6-9]

If you spray too much I agree, but I've never had that happen

Some of you are a little to dependent on copper spray. Only time i use it is for a MLS headgasket.

Personally, I do not think you need it, unless you have a bad scratch or gouge in on of the sealing surfaces.

If all the surfce prep is fine, clean and dry, just install the gaskets dry and go on with the build

^^ I agree. Not even the 4g63 rebuild manual tells you to use copper spray. Its a preference thing but people are starting to think its necessary for some reason. I did a rebuild using copper spray only on my MLS headgasket and have no leaks anywhere.

 

[ed1380]

I've done MLS installs dry with no leaks

I really only use it (and lightly) on things like the front cover gasket, water pump gasket and things like that.. also use it on exhaust stuff but gold or silver spray paints have something in them that work much better which was something past on to me by an old timer at a garage i worked at years ago

I definitely use it for all paper gaskets. I don't believe I've ever used it on a metal gasket. Yes, you'd want to spray both sides.

I use the Mopar Pink gasket spray. Seems a bit better than copper spray. I only use it on headgaskets, never really tried it on anything else. If the surfaces are clean and free of anything...I dont see the need to use it. Unless you feel the need to have that extra security...do it

I personally use it for any paper gasket, and exhaust gaskets. Light coat both sides.

I use high tack sealer for head gaskets.

Thanks for everything guys. I don't think my surfaces are that bad but I will add the copper spray for the added security.


It can't hurt can it If I put on light coats on each side?

Never used in on an MLS gasket and never had a leak. Used in on exhaust manifold gaskets in the past, but i think it's necessary unless you have a damaged surface or warped surface.

Same here, i've never used any sealant on a head gasket. If the surface is right and the gasket is good than it should seal just fine.

Also, should I use loctite or anti seize on all of the bolts (manifolds to head, turbo, TB etc)?

 

[TexasTurbo]

I'll give you 3 guesses as to who didn't use any copper spray from the factory when installing head gaskets..... and the first 2 don't count.

The guys over at MAperformance told me to apply a light layer of automotive primer to my MLS head gasket when installing it. They say it help seal better.
