More clues.

I pulled a little more of the engine apart yesterday and here's what I found:

All rod bearings and journals are destroyed, all main journals look pretty darn good.

This is confusing to me. I assume that the oil has to go through the mains to reach the oil holes in the rod journals. Why didn't the mains go?

I won't put money and time in this engine unless I can find the cause first.

Thanks for any comments you may offer,
Larry
