CaseyB42 Posted April 25, 2016 Share Posted April 25, 2016 I am evaluating a B-42 with an EN402. It sat for about 15 years before I started it in Fall. Today I started it again and ran it for an extended period. The oil pressure was reading 20 psi at cold idle, and never climbed beyond that. However, after some time the oil pressure began to drop and a knock became more pronounced. I would appreciate any input on: 1) whether it is worth trying to flush out the motor with diesel or another oil treatment 2) whether this motor is junk and I should look for a new one, or 3) if bearings are available and the job is reasonable Quote Link to comment Share on other sites More sharing options...
