Scored a low mileage 4.0, 1996.
Runs GREAT. It has been sitting for 2 years before I got it. Today, I went to check the motor out real good, and I let it run for half an hour.
Temperature shot up to 230, it boiled over, so I shut it down.
THE ANTIFREEZE WAS BLACK!!!!!!!!!.....Not black like oil and water mixed like a blown head gasket would be. (The oil is still crystal honey clear) but black like.......exhaust smoke, maybe? It is definitely antifreeze, (checked to -10 degrees) but the color has me worried.
I did a compression check (plugs were fairly clean) and the compression was between 130 and 145 for each cylinder
Could the head gasket be blown between the cylinder and the water jacket? Or maybe just crap floating around in the coolant systemn from sitting?
