News - good or bad - This Afternoon, he pulled pan on block and oil pump pickup was rubbing on bottom of pan. Pan had a slight bent in depression. Measuring from block pan bolt on surface to bottom of pan and from the same surface to bottom of oil pump resulted in the same measurement. So pickup was flush with pan, not even a quarter inch off. This may be problem but there may be others as noted by suggestions.
Jerry, boat is mounted forward and is a standard rotation. I will ask about pan angles to see if he was also loosing the ability to be in the pool of oil. I will also ask oil viscity and running temp. Lakes he was in likely had a surface water temp of low to mid 70s. Prime lake is at 4,300 ft.
36 Sedan, when the engine sat it was with basically no oil. Only water could be from condensation. He disassembled engine and looked at all bearings and cleaned all parts. The only thing he did not do was to probe the oil galley lines.
Denny, the engine is likely from mid 70s. It has a 2 piece rear main seal and 2 bolt mains.
