360 running on 4 cylinders
My son and I tore the engine down today. #6 was the culprit for sure. It had a puddle of oil on top of the piston and it looked like this when we pulled the piston out. You can clearly see a diagonal ridge on the side of the cylinder and some nasty scaling? Not sure what went wrong, but that was the problem.
PO told us this engine was rebuilt, but I seriously doubt it. The crank bearings are totally worn out and the smell when we pulled the crank told me there was some nasty 46 year-old oil hiding in there somewhere. I still can't get the stink off my hands.
Sending the block off for inspection to determine next steps.
