I replaced my
oil pan gasket a few months ago due to leaks and it is now leak free. I used a Felpro rubber/cork gasket and Dow Corning 732 sealant. Here is what I did:
1. Removed the
oil pan and cleaned the surfaces with a razor blade and then laquer thinner.
2. Smeared sealant on the block side of the gasket. The smear was thicker than paint but not so thick that sealant would ooze out.
3. Stuck the gasket to the block and installed the
oil pan, bolting it up a little past hand tight. The purpose of this was to stick the gasket to the block.
4. After sitting overnight, I dropped the pan. With an xacto knife, I carefully trimmed the gasket flush where it was hanging over the ream main drainback and bolt recesses. I didn’t want oil sitting on top of the gasket.
5. I smeared sealant on the top surface of the oil pan and reinstalled the pan, tightening the bolts. I let is sit overnight again to let the sealant cure.
6. After the first and second drives, I snugged the bolts again. I have an aluminum block.
It has not leaked since (knock on wood). Good luck!
