most of the time it is the push rod tubes we have found. also front engine seal can be hard to find for sure.

I am afraid that is what I am going to be faced with as well. My C-90 is leaking more everytime I fly and seems to be coming from several sources.

Fixing it was a slow process that took time. 1. Replaced two pushrod tubes with the Real Gaskets conversion. 2. Replaced the tach seal. 3. Replaced the oil cap gasket with Real Gaskets silicon and bent the oil cap tabs to get tighter seal. 4. Installed a bracket to hold the fuel pump pin, which was creeping out of place and leaking. 5. Overhauled the engine, including resealing the crankcase and installing the last two pushrod tube conversions. My plane is not perfect now, but oil leaks are truly insignificant.

LOL. The plane gets wiped down after every flight. Even at each fuel stop on a cross country. My A/P is one that believes a Continental that doesn't leak is out of oil... :) Actually we have given up looking for leaks (unless it gets suddenly worse). He found that someone in the distant past has prosealled the entire seam of the crankcase. Oil is seeping thru the proseal. We will make the leaks go away at overhaul time. In the mean time, I am reading everything that is written on this subject. So far, everything that has been mentioned has been done to Honey. Bob D.
