4AD exhaust flange gssket

Post by Grantbradley »

Trying to find an exhaust flange gasket for my 4adt.
Anyone have a spare?
I am reluctant to make one as the reviews on sheet gasket material are not great. Thank you

I have found that an exhaust sealant will make up for any deficiencies in a home made gasket so if all else fails you could try that.

I fabricated a gasket from high temp gasket material purchased from NAPA, then added a thin layer of high temp silicone based sealant to both sides. Still leak free 8 years later.

I should add not many miles in that time, but hey...

I also used a .4" thick stainless exhaust flange I had made, which helps some.
