Had some down time this weekend due to the rainy (unusual for SoCal) weather, so I decided to pull off the cowl and do some minor maintenance on the engine. Engine is an IO-320 E2D solid crankshaft with 18 hours since full overhaul. I'm assuming the oil ring at the front of the cowl is due to a bad or leaky crankshaft seal, but figured I'd post this to get the advice of the VAF collective. I changed the oil at 10 hours and put 6 quarts in and the oil level really hasn't changed at all, so what you see on the cowling is very little oil, but enough to make a bit of a mess. I've consistently had a bit of a oily streak in the same location during the previous flight hours, but haven't had the cowl off since the oil change at 10 hour, so this is 8 hours of leakiness and in the previous flights I had the cowl on and off more often.
Is this seal messed up and should I replace it now, or can it wait?
Bottom cowl.
Top cowl.
The flywheel and starter ring gear don't seem to be oily, but it just may be all flung off as it leaks.
