I recently changed the plugs on my O-540 (PA32-260). After about 50 hours I noticed that a few of the plugs are developing an oxidization on them. Several look fine but two of the plugs show what appears to be a bit of corrosion. The engine is running well and all temps are normal. Does anyone have any insight?
