head gasket sealer - again

Dan W MN · Sep 25, 2010

Hi all

I've been browsing the archives for a while now but havn't found anything addressing this: I have a new head gasket to install, one side is bare metal and says sealant required. The other side has a blue coating that I believe you're not supposed to use a sealer with. Should I just use it on both sides? lemme know what you would do.
Thanks for your advice, Dan

Could depend on what engine you are using it on.So what are you using it on,could help

It is for a 48 M International. I was jsut out looking at it again - I guess the one side is a grey fiber material, this is the side that says sealer required. The other side is the coated steel, sorry about the confusion.

copper-kote is good stuff spay some on let it dry maybe four or five coats. then put the gasket on .

Spray both sides with copper coat spray. Use it as you would paint. One even, but sparse, first coat, then a covering coat, not excess thickness. If it says use sealer it means both sides. Jim

I would use the copper spray. So far, so good on all the older engines I have done, all flatheads in cars driven hard daily.
The old timer that helps me out with stuff said to spray the threads on the head bolts and they won"t leak water around them. He was right, so seepage around the bolts.
