Averkam, as the former owner of two Alfa Romeo Alfetta sedans I have seen oil in the coolant a few times, it is quite common with Alfa engines. Let me point you to a local north Georgia, Southern Jeeps, who's members are always converting something. I know a few of these guys have converted 2WD Cherokees to 4WD and one of them did the conversion to a Comanche.

Too many 4x4's, not enough time or money
