Well I checked it out with the list, got back 4 replies so
far which is pretty good for a nice weekend. They went like
1) 1900 hours in 22 years on an O-360, 100 short of TBO but
good for the number of years.
2) When I had my O 360A1D overhauled it had about 2150 TT. It
was still running strong but was starting to use oil.
3) The previous owner took my engine to 2535hrs before having
it overhauled. Apparently it was running great when he
had a minor prop strike and the insurance co. o/hed it.
4) My TSIO-360-GB4 is currently at 1980 TT, 180 hours past
TBO. It had a top OH at 1260. Compressions are still good
and it uses a quart every 10 hours.
I think they are pretty good results from an admittedly very
small sample. In the five years Ive been on the list I
dont think Ive ever heard of an engine which fell seriously
short of TBO.
