I have a 1998 S-70, Non-T, automatic, Good shape cosmetically, 235K miles, Engine seems sound but has an oil leak at the split between engine and trans. Rear main? PCV system? Not sure. I am at a cross road as to rehab it, or sell. If rehab maybe some mods to make it a little more interesting, performance or cosmetic mods. I am completely unaware of what is possible with this car as a platform for a project. Any guidance out there?
