15 hours into an 0360 overhaul,
Appears front main seal leaking and getting worse.
Replaced front seal. Did a compression check, all cyls at or above 70 (cold)
Flew a half hr and seal is leaking again.
I’m running a raven inverted oil system.
It possible two bad seals , but wondering if I’m building crankcase pressure?
How to check?
Thanks,
Doug
