LS3 Oil Pan Gasket - Lateral-g Forums

1965_SS · #1 12-16-2015, 04:35 PM

I've got a new GM crate LS3. I need to change the stock oil pan over to a Holley for my car. Is it ok to reuse the pan gasket or do I need to buy a new one?
Thanks.

Reuse the one that came on the crate motor. You'll need to drill out the 2 rivets.

Exactly what he said. Drill the rivets out and when reinstalling i actually used a thin coat of silicone.

Only put sealant on the 4 corners where the front and rear covers meet the block

Wow, thanks for the replies! I would have never known to do that. Once I get the pan off I'm sure I will see the rivets you guys are talking about (still sitting on crate).
Any good LS books out there to get my knowledge up on these engines?

You drill the holes before you take the pan off. Undo all the bolts. Tap the pan with a mallet, and lift. You will see where the rivets are holding it on. Make sure you have a razor blade also as you might need it
