Hi, friend at work has this car with 62k miles and was told by 2 oil changing shops he had a MOL. So, being a Chrysler retiree I wanted to put this to rest and looked under the car. The K-member/sway bar and engine/tranny parting line look damp. This was after shop cleaned off the previous mess. It looks to be a rear seal but I was thinking the new hardware was leak proof at least that's my experience. I Googled this topic but didn't see a lot. Do the 3.6L have some problems with crank seals?
