Copper Coat headgaskets?

[welpro222]

Is copper coat recommended for 6.2 Fel-pro headgaskets? I'm going to be using Fel-Pro 6.5 Head Gaskets.

You talking about something like this?
K & W Copper Coat

Yeah thats the stuff, usually found at NAPA or O"reilly's Auto parts stores.

I don't see why. Seems you only need it for the high-speed copper head gaskets. You shouldn't even need sealant for a regular ol' head gasket (like a Fel-Pro)

I've used copper coat on all kinds of gaskets. I don't know if it helped or not but it hasn't hurt. None of the gaskets that I used copper coat on leaked. I have put them on dry before and they leaked.

There isn't much I dont copper coat. I'd copper coat my doors shut everyday if it wouldn't get my clothes dirty. It's like sour cream, or bacon; goesn with everything and improves everything it touches.

When I was a Subaru technician I used copper coat on all gaskets including head gaskets. Never had a problem.

In mechanics course we sometimes used copper spray paint in a pinch. seemed to work just as well

Never used copper coat. Never had issues....
Not even on MC or briggs stuff.

On gaskets that don't see extreme heat like head gasket, manifold gaskets, and such I like to use a product called Indian Head gasket shellac. Do not put Indian Head on gaskets that you plan on removing anytime soon though. That stuff will glue the gasket to the mating surfaces like you wouldn't believe.

My old man always used 3M Super Weather Strip adhesive to glue head gaskets to the block. Might have been a holdover from the old days but I've never had a head gasket leak when I've done it. This for for non-coated gaskets obviously.

I've been using copper coat for 30 years or so. I've never had a gasket leak with it, and it always was easier to remove than with it than without it. It's something my dad as a diesel mechanic swore by, which was not the normal swearing he did. He was the one who told me it wasn't that you had to, but that it was better with it. But some of the other posts are 100% correct, it gets EVERYWHERE.... one other nice thing it does it to hold the gasket in place while installing. on a chevy 350 oil pan in the middle of no where with just yourself to work on it, priceless.

My deuce has a fresh rebuild engine that I have experienced head gasket failure with . Upon tear down and inspection the head gaskets were coated with copper coat . Head and block surface you could still verify that they were decked , inspected for square no problems !!! I have many years repairing large natural gas engines 1800 HP + !!! Never coat newer composition head gaskets with anything they are designed to be installed DRY !!!! Copper or steel shim gaskets need to be coated .

I also copper coat alot of gaskets on engines but I wouldnt do head gaskets. Fel-pro makes pretty good gaskets so i would go dry!!!!

The PDF file that I posted came directly from Fel-Pro. You'll do some digging to find it as their site sucks.

Unless the gasket manufacturer specifically calls for a sealant/chemical to be used, I'd install dry.

With the vast number of vehicles now using aluminum cylinder heads, applying copper sealants with aluminum and steel can set yourself up for a galvanic corrosion issue.

That's all I'm going to say on that.
