Jerry:
I would concur with the observations of Tom regarding lifters and cam.
Just want to relate another data point with my experience...
1. My plane had O360A1A that was new in 1969 with around 900TT when I
purchesed it
2. Plane had been out of annual for around 12 years, but was serviced
twice a year with oil and engine run.
3. Completed oil pump AD, so accessory case gasket was replaced. Also
replaced crank seal
4. Put around 400 hours on it and started seeing higher oil
consumption (no chips)
5. Had issue due to cracked plastic pushrod tube
6. Put another 200 hours on it (no chips) and decided to pull a jug
during annual to assess internals due to compression anomolies
7. Several mechanics looked and there were mixed feelings and
predictions (50-200 hours left) about condition of cam
8. Decided to overhaul (first time since new) at 1500TT (still no chips)
I attribute the low time before overhaul to the lack of use over the
years.
However, there were no major leaks noted that could be attributed to
gasket failure except the crank gasket noted above.
FWIW

Folks in the know...
Please weigh in on this. If one were to push the longevity of
a 2000 SMOH
O-360 by doing a top overhaul, what would be a reasonable
expectation of time
remaining?

Please also remember that most of the dollars in an overhaul are in the top
end.- Might check and see what more you would spend to go through the bo

. If one were to push the longevity of a 2000 SMOH O-360 by doing a top ove
rhaul, what would be a reasonable expectation of time remaining? Given exce
llent care, would another 500-1000 hrs be unreasonable? I've seen various a
necdotes of 3000+ hrs, and I realize there would be a ton of variables...
