I put a Fel-Pro perma dry one piece oil pan gasket on my engine along with a summit chrome oil pan, and it leaks like a bloody nose. I cleaned the block surface as well as the pan, and installed the gasket dry. It still leaks. This time I got a new GM oil pan from the ZZ383/425 engine and a new GM oil pan gasket.

Should I use any kind of sealants on the gasket?

It seems to be leaking the most where the gasket touches the aluminum rear main seal housing.

Any tips on how to seal it up like factory?

Thanks

trash the chrome oil pan and run a steel piece from the factory. i've never had one leak, with the 2 or 4 piece gaskets. any more one piece gaskets is all i use.

Oops, never mind, see you're havng issues with a stock pan.


Never used a 1-piece gasket, can't help.

chrome can be a punk to seal

i built a 355 for my dad, he got alot of chrome stuff... timing cover, valve covers, oil pan

i made him take it all back and spend another 200 bucks on piecing together some good aluminum stuff all around after complaining alot and having him read up on it a little.

not to say they are always problematic

but alot more so than a stock or aluminum piece

grab a one piece gasket and i bet you'll be fine with the stocker off that crate motor, be sure to tighten each bolt a little at a time so you don't warp it. i always make at least 3 passes before it's all torqued down, it's good for sealing AND piece of mind. lol

This stuff is used in the truck industry. It's used to make pan gaskets on International 444E engines. It's used for front cover gaskets on Cummins 5.9 and 8.3 engines.

The stuff is great. I use it for the front and rear gaskets on my intake manifold. It sticks to dirty metal and once it dries, you'll need to cut it to remove the pan. If this stuff doesn't stop the leaks, you have other problems.

Thanks everybody! I've have been hearing good things about "the right stuff" by permatex. I think I will apply this to the ends of the engine in the problematic areas.
