I have personally changed my oil pan gasket about two weeks ago.
It is a pain in the butt but i figured where it was leaking oil. It was from the oil filter flange gasket which is on the driver side. I took me about 3 days because i had school and also because it was such a tidious work. The engine has to be lifted thats for sure and you might want to take out your rack and pinon out to have some space under there..In the end i think i had done wise decision because the rubber on the gasket was real stiff and was about to go out the door already. Tell me what you need to know ill guide you.
