I just recently purchased a 1997 Intrepid w/ 3.5L which only had 71400 miles on it but, after getting it home from the dealership, noticed it leaking oil. Looks like the rear main seal is bad. I'm fortunate that it had a 30 day 1000 mile warantee. So far they have replaced the valve cover gaskets, intake manifold (to fix rough idle and engine misfire), fuel injector. They are going to replace the rear main seal. Do the have to pull the engine or the transmission to get to this seal? Oh ya, I'm feeling very fortunate! This car is great shape but I really missed it on the oil leak (kinda hard to look under a car when there's snow and ice on the ground).
