HELP - Looking at a 337
GMAS and others, I'm looking at a '73 337G which has had a recurring oil leak on front engine cyl 6 where pushrod tube goes into case. At last repair, the mechanic (who's a good one and 337 savvy) noticed that the case hole was bigger than it should be, with the tube going into the case with little friction; which explains why every 2 years or so it leaks again. So he not only replaced the seal but added a sealant. Engine is 1200 hrs SMOH.
Questions. Is that likely to fix the problem. If the leak fails in flight, what's the worst-case leak rate (1 qt per hr? 5 qts per hr?). Would appreciate earliest possible answer.
