Oil Drain Return Lines

[Releew]

Been noticing some oil drops bleeding from the cowling....  Not much, but was never there in the past.  Just a heads up, be sure to pay attention to the Oil return lines when you are looking over your engine.  On my Cylinder #2 the baffle was chaffing against the tube and was close eroding through.  The other tubes were fine but the rubber tube connectors had been tightened so may times the rubber was bottomed out.  All creating minor leakage.  New tubes, connectors and clamps are on the way.

Overtightening those clamps is a common problem my favorite mechanic warned me about. Seems some people think they need a half turn every time the cowling is off as a preventative measure and that causes the problem you noticed.
