it has a gas engine head gasket for a real old 1.6 or 1.7 carb gasser LOL. plus the headbolts were reused. (can see them stretched) it was the head gasket, never saw one this bad.... real bad, feeding oil from the high pressure feed into cyl 3 and 4.
i am upset that the owner was not at all honest. He new there was a problem and played stupid.
