In a previous post I think I referred to "leaking cam seals"....not true.....my leak (I think) is a crank seal. Mechanic I consulted estimated 4-5 hours labor, and mentioned the possibility of a leaking oil pump once he is able to get into the area where the leak has been detected. Does this sound reasonable? Anybody have similar experience(s) with this problem? TIA, Mark mtrank@acva 87 5KCSTQ 142k+ miles
