Looking for advice... My O-320 started leaking oil which I discovered after finding a larger than usual puddle on the ground and burnt oil on one exhaust. I tracked it down to the Vernatherm and discovered that there is a Service Bulletin on it. I got a new one and installed it. It came with a new crush washer. I noticed that the old crush washer had a defect on one surface.The leak is almost gone but I am still getting a few drops after a 20 minute run up. So I am sure I am on the right track. Should I try to fix this or stop obsessing and go fly? I got some advice to reinstall with Red RTV smeared on the crush washer but reticent to do that. All advice appreciated!
