Lycoming general Quality issue
I have now had three sets of O-235 cylinders only make 600 hours before piston pin plug problems, one cylinder set only made 290 hours !
The engine that made 290 hours from OH then has a shock load inspection at 400 hours and the camshaft and followers required replacement.
Another of my engines has now had to be overhauled due to cylinder and cam issues having only run 1300 hours.
So at the moment Lycoming seem to be producing O-235 Cylinders that are good for 600 hours and cams that are good for 1300 hours.
Thirty or so years back when I started in this business you could expect an O235 to run to 2400 hours with one cylinder change at mid life, my only conclusion is that Lycoming have let their quality control slip.
I am now adjusting my having to adjust my prices to reflect the fact that a Lycoming engine is likely to only make half the TBO that they recomend.
