Title: Drain Bolt Gasket
Post by: camshaftit on June 26, 2008, 05:49:27 PM
What is the original material for the oil drain bolt gasket?

Are the engine and trans drain bolt gaskets the same material?

Why use copper versus nylon?

Manual transmissions only had a fill plug (no drain plug), and it was an NPT pipe plug; automatics had no drain plug either.

My original M22 has a drain plug (NPT pipe).

Nylon will conform to irregularities in the pan & bolt head with much less torque than that of copper. It's much softer.
I use the nylon washer/gasket as supplied in the felpro gasket kits, and they work just fine. No leaks!

Correct - original M22's had a drain plug, and all Muncies from 1970-up had one too; many pre-1970 Muncies had drain plugs added during rebuild as a convenience.

Would someone please confirm this?   I've seen a number of TH350's with drain plugs...  don't look like replacement pans.

powerglide transmissions have a drain plug as well don't they?
