Have a leak where the oil temp line meets the accessory case. Have replaced the crush washer twice in the last few weeks and it doesn't seem to make a difference. Always get a small bead of oil at the base of the crush washer after running the engine for a few minutes. After flying, an accumulation of oil is sprayed along the belly of the cowling/fuselage, which makes me think the leak is significant, despite the fact that at idle/low RPM it appears minor. Any suggestions on what's happening and more importantly how I can remedy the problem? Much appreciated!!!!
