head gaskets

just wondering about the strength of the moby headgaskets. is it alright to reanneal and normalize them more than once?

Re: head gaskets

I don't know about reannealing them, but I do know that a beer can cut to fit makes an excellent replacement.

You can also use valve grinding compount and lap hone the head and cylinder surfaces together, if the piston dome won't bump the plug without a gasket being there.

Re: head gaskets

I'm not really sure about the beer can. I'm pretty sure that the aluminum alloy in a beer can is much harder than the the aluminum jug and head surfaces. It's doing nothing here but taking up space. A softer aluminum or very malleable brass shim stock would probably be better.

When you remove a head gasket you should be able to see the machining and imperfections of the head imprinted onto the metal - that means it was doing it's job. I doubt you'd see anything like that on a beer can gasket no matter how much you torqued down the head.

Re: head gaskets

i make gaskets out of coke cans and they compress just fine. i see plenty of imperfections.

geb that is why i am wondering about annealing the used ones.

Re: head gaskets

I've annealed them a few times and it worked just fine. Got a great seal. Make sure not to over-torch it though, it will oxidize if you heat it too much, then it gets warped and doesn't fit well anymore

i was thinking of getting some copper and making a more permanent one

Re: head gaskets

I second the beer can gasket. It works. It's cheap and easy.

dont use one.

its not necessary

Re: head gaskets

I didn't know anything about re annealing the gasket, I just put it back on. I'm gonna take it out though and use a beer can gasket, I happen to like canned beer.
