Anyone have any experience or recommendations on make your own exhaust gasket material.

Trying to resolve a leak on a JK with a 3.6 and the paper thin OE stainless gaskets are not working.

The Pentastar 3.6 does not have a traditional exhaust manifold - the exhaust pipe bolts directly to the motor with 4 bolts.

The gasket is ~ 5" X 4".

Looking to find something with some thickness to make my own.

Thanks!

dead soft copper

Is that a brand or material?

It is a material, dead soft refers to the hardness which in this case means that it is annealed to make it very soft and conformable for high temp gaskets. Or in a different application, crush washers for banjo bolts.

Either the head or flanges are not flat. Fix those first then the stock gaskets will seal. If they are warped others gaskets will eventually fail also.

Thanks!

I did a quick search and can't find any dead soft copper blanks/sheets.

Any ideas ?

Check to see if the flange is flat first.

Thanks for the link.

Trying to get my hands on a small piece ~ 6" x 6" to make a gasket out of.

You can always make your own from regular copper sheeting, take a sooty flame from your O/A torch and cover the surface with soot, then reset the flame to neutral and heat up the sheet till the soot cooks off. It should be pretty soft at that point.
