Leak from the bottom of the sump on a 61 is land immediately, ditto on a 225, 139 etc is 30 mins.
HC
Pls can you clarify? Are you saying the 225 is the same as the 61; leak at the bottom then land immediately? Or are you saying that the published RFM on the 225 and 139 say "land within 30mins" if there is no oil?
Did we get an answer on how the 139 achieves the 30mins dry running? Any special cooling system or something?
