I made the ultimate mistake! Went on a road trip in my 1985 CJ-7 Jeep, has a transplanted 400 chevy sb, and I forgot to check the oil. She had no oil, overheated and I pulled over thinking I had seized the motor. I bought some oil, topped it off, and it started with hesitation. She'll run, but it sounds like someone is playing spoons under the driver side valve cover. Is it a valve? lifter? did I bend a rod? What do you think?
