A friend of mine told me I should have the exhaust manifold surfaced before
re-assembling. It is not rusted, but not perfectly clean either. What are your
thoughts? how much can the gasket cover up?
Actually, the gasket can cover quite a bit up. While I am not arguing that you
should or should not resurface your manifold, there is a thick spongy graphite
manifold gasket made by Remflext that come in standard 1/8 inch thickness and
are designed to crush 50%, which allows it to fillgaps in teh flange surface of
up to 1/16 of an inch.
I developed exhaust leaks twice after my rebuild, installed one of these, and
am delighted that I can now cruise at 80 mph without having to worry about
blowing it again.
Uhm...I just can't find my receipt to tell you who I bought it from. (...Guess
that means NFI, huh?) Joe Alexander, was it you????
