The last 15 hours or so my C-90 spit oil on the lower cowling. Cleaned the engine with some decreaser and blew it dry. After flying around I found three locations with leaks: Right side of crankcase cover, one flange where the pushrod tubes are going in and on the oil tank gasket.
I tightend some srews, some were quite lose! It is much better now however the leak on the crankcase cover (it is close to the pressure relief valve) is still there. I can live with it for the time being, repair is not urgent. Is there a trick to address a leak like this or do I finally need to change the crankcase cover gasket. If so what else need do be done to change it? Engine is a C-90-14F
