Rebuild needed?

Posted by Clipper55super On 2018/1/20 20:53:36

Quick question for everyone. I have a 55 Clipper Super and it developed a knock the last time I drove it. I pulled the engine and noticed 2 push rods that were chewed up, assuming this is the issue. When I pulled the heads, 6 bolts had grey sludge in the bolt holes looking like oil and coolant mixed. The engine has sat for a few months and the sludge did not drain out of th bolt holes. Is this a sign of a cracked block? I don't believe so, but looking for opinions. My believe is the head gaskets we're bad. The cylinder walls look fresh and when the oil pan was pulled, I noticed on crankshaft bolt wasn't even threaded in.

Thanks in advance for your input.
