Well, I read all the posts on the oil diverter plug for changing the engine to full flow filter oiling. It seems that there were a bunch of opinions as to whether or not the plug should be flush with the block or driven in approximately 1/2 inch to divert the oil from the pump, out the normally plugged NPT hole, to the filter and then back in the aft NPT hole where the pressure gauge sometimes sits. My 261 was never set up for the filter and the plug is flush with the block. Is the consensus now that the plug needs to be driven back for full oil flow? Thanks!
