Coming back from Montgomery Our motor home spun a main bearing.
Jim brown had a rebuilt engine in his collection of parts. I test ran the engine on a motor stand, everything was ok except the new fan clutch didn't engage and the temperature got too hot so I shut it off after 5 minutes of run time. I wasn't sure about my temp gauge as it didn't read the same as an IR probe that I had. Ran again and shut down after another seven minutes due to overheating. Next morning I started it up again with a vacuum gauge and set the timing, it was a bit too advanced and I was able to run for 15 minutes before overheating.
With the run time that I had I found a couple of oil leaks, one on the back China Wall and another on the back side of the oil pan.
Removed intake and found that it had a turkey tray and no block offs. Ordered the Mondello block off plates and gasket. Removed oil pan and two push nuts were in the bottom of the pan. Fits a 5/16" shaft and .540 O/D.

Where did they come from? I won't think an engine builder would use such a cheap fastener. Did they originate out of the inside of the motor. The motor does have roller lifters and double timing chain sprocket.
Sorry unable to take any pictures ans our camera broke on our trip to Montgomery.
