Hey gang,
Just uncowled for oil change #3 on my Aerosport O-320 and found several new oil leaks that have appeared between 40 and 65 hours. I'm curious if anyone has had experience with leaks in these spots, and are leaks like these inevitable on threaded fittings somewhere on the engine? All the rental birds I ever flew sure seemed to have em...
#1 seems to be leaking from the threads of a stud where it emerges from a nut. Sad to say I do not know what this thing is for -- forward upper left side of crankcase. Torque seal still intact from aerosport, just now I put a 10" wrench on it and couldn't tighten it further.
On the plus side, I can keep an eye on this one without decowling. Looks like it has leaked about 15 drops of oil. Made a nice mess against the back baffle wall.
#2 is the oil quickdrain, leaking around the threads. Was installed with ez-turn, and cranked it in as hard as I could with a 1-foot wrench. Not enough?
