Oil Pan Gaskets

[skeazle]

Anyone know which is the best oil pan gasket material to use, cork or paper? I haven't dropped my pan yet and I am not one hundred percent sure I need new gaskets but I have a lot of oil leaking between the oil return pipe and the top of the oil pan. I think it's coming from either the oil pipe or the oil pan but either way I want to replace all the gaskets involved. Jim
