5000 hrs on a piston eng hey Wiz?
Actually, it was a little over that. replaced one cylinder, due to a broken ring, and while I had the engine in bits I did the rings in the other cylinders. that was at about 3600Hrs TSO.
was still going strong when I stopped operating it with all the comps in the high 70's, (78 average) about 2 Ltrs of oil in 100Hrs and fuel burn unchanged.
Just have to love the 0320D2J. was thrashed as a mustering machine for nearly all those hours too.
