I have a 383 LT1 with a Canton Oil Pan (242T). I have changed the gasket twice and it is till leaking oil. The gasket is a Felpro and I put RTV on the ends where the gasket meets the block, not where the gasket meets the pan. I can't seem to get rid of the leak. Looks like it is coming from between the gasket and pan not the gasket and block ( where it has RTV) but not sure. Should I get a different oil pan? Could it be front or rear crank seal, how can I tell?

Like any fluid, oil will run "downhill". So, it's possible that something else above the oil pan rail is leaking, and finding it's way "down" and showing on the oil pan.

My recommendation would be to give the engine a quik bath with Simple Green and low water pressure to rinse it off. Try not to get the Opti wet, then drive around a litle, and see if the oil path can be seen more clearly.

some have better luck than others on sealing aftermarket pans. Putting RTV all around on both sides of gaskets seems to fix the ones that leak...but removal after that is harder.

confirming source of leak as advised is what you want to do. Oil dye and a blacklight can help that.

A trick I've used in the past on my engines is to slightly loosen all of the pan bolts then let the pan drop very slightly and take silicone and spread it push it between the edges of the pan all the way around then tighten all the bolts. Then use your finger to smooth the silicone all around the pan and let it sit overnight, I've never had one leak after that.

Thanks guys. The oil is definitely leaking from the oil pan. I think I will try RTV on both sides I'd the gasket. Thanks for the replies.
