Looking to buy a 95 E320 wagon. The owner tells me "It runs well but is leaking oil from the head gasket. Not a lot but it leaks onto the fan belt." and sent the following photo:
Car has 249K and the current owner put 1/2 of those on in the odometer during the 7 years he has owned it. Based on google searches this appears to be a common problem with the M104 engine. I'm 263 miles away from the car and trying to understand what I'm getting into before its too late.
PS: Replacement of the wiring harness hasn't been done during this ownership and he has no records from before. So I'll assume the worst and if purchased plan on doing it as part of the head gasket replacement.
