Ahhhhh.... what about the engines?

[Eustacio-Chachi]

I agree with Gmas that there has to be many airplanes being flown with probably more than 20 years since OH on the engines.
If TBO is 1400 hours you should fly 117 hours per year to make it 12 years, if I fly mine 52 hours a year, that is one hour a week, it will be 27 years before I reach the 1400 hours.
The question is that if I have high oil preassure and low oil temperature plus oil conpsumtion is low (1 quarts per 8 hours) should I worry about the engines being 16 years since last overhaul?
