Normally the Cessna doesn't leak oil. I have flown it quite a bit lately, and I noticed a teensy bit of oil coming out of the cowling. I don't know if it is my slovenly habits when checking the oil level or maybe there is a leak as a result of the annual. I looked around inside and didn't see anything obvious. There was a bit of oil on the underside of the magneto flange, so I tightened the magneto a bit and we will see what happens.
Looks like a little oil around where the filler neck is pressed into the gearbox casting. You'll want to spray it all down with some isopropyl, let it dry and run it for a while to see what else might be leaking.
