Remember oil pump is turn by camshaft
Hi Ken
Are you taking into account the camshaft turns at a lower speed than crankshaft, if I remember correctly. Don't have manual handy to confirm the difference.
Now as to oil pressure on 216 after rebuild I'll check my notes but the 40 psi sounds correct for drill prelube. Cranking the engine while using the drill is a good idea to be sure the engine is fully lubricated.
Did you use the heavy assembly lube as you put the engine together? If so that will increase oil pressure until it is washed out by the engine oil.
The splash/spray lubrication is a very high volume pump and the nozzles on the crank sprays will take care of most over pressure situations like a stuck pressure relief valve. My concern would be is the spray branch is blocked. If I remember correctly the spray can be confirmed by removing the fuel pump and looking in while priming with drill.
Please keep us posted on your progress.
Cheers Phil
