I have a 98 Chrysler Intrepid (I'm Canadian) with 65,000 km on it. I went in for an oil change today and a certified DC mechanic told me I have a Differential Leak. He said that the early models had a bad design on them (something to do with the vent) and that there is a TSB (Technician Service Bulletin) for an add on replacement part. If enough TSB's are reported, it turns into a recall. He said the differential leak is not too expensive to fix, but since there is a TSB it might be free. I'm just wondering if anyone else has had this brought up to them. Also, the mechanic said I MAY have a "Rear Main Seal Leak" or a crack in my oil pan. He said nothings for sure but that if that repairs would be costly if there indeed is a problem. He said that he has seen a couple of Trep's with cracked pans. Has anyone had any of these problems? How much should I worry? Any info on how/why I may have these problems. All my kilometers are city driving... Any help/ideas are appreciated..
