QuestionI own a 2000 Grand Cherokee laredo with the 4.7L V8. My oil pan is rusting through and starting to drip. The seal is good, and its not leaking from the drain plug. I would like to replace this myself and would like to know if I need to remove the y-pipe or anything else to easily remove the pan? Can I use RTF to seal the new pan in place? Any tips?
