Hey guys

My oil pan is leaking, I ordered a replacement Delco filter which came with a cork gasket.
It looks cheap, and Ive heard cork tends to leak...Should I buy rubber gasket?

If you use the cork gasket with Permatex #2 Form-A-Gasket sealant you will be just fine.

People that use cork gaskets that leak is usually due to over torque bolts or warped pan. With a properly prep surface and a flat pan you will be good rubber or cork for the trans pan. Use a little Vaseline on the gasket to hold it in place as you mount it, and don't over torque.

But with the cork you will need to go back and re torque the bolts.

While you have the pan off check for flatness around the bolt holes. If someone over tightened and it's not flat new gasket will leak no matter the type.
Personally I would use a rubber gasket.
