Well guess its my time...
Annual Time
Today we found some metal in the oil filter of the right engine, pulled the screen to investigate and nothing in the screen. Compressions all came out 74/80 or above
it runs well, seems to develop power and no obvious issues Oil temps and pressures are good
Now this engine is 1100hrs smoh, however it has had some new cylinders over its life time, the newest ones were installed 2 years ago and have 98 hours on them. at that time the cam was inspected and was good
cyl 1 - 1100tt
cyl 2 - 98tt
cyl 3 - 221tt
cyl 4 - 1100tt
cyl 5 - 98tt
cyl 6 - 1100tt
at the last annual it was switched from mineral oil to 100w Plus,
This engine also still has 3 chrome lycoming cylinders on it the rest have been replaced with standard lycoming cylinders, cyl 1,4,6 are chrome
Wondering if the metal could still be from break-in ?
thoughts? my shop is an engine shop as well and has recommended following lycoming service bulletin,
change the oil and filter and fly 25hrs then re evaluate...
I trust my shop, just wondering about if its likely it could still be from the new cylinders breaking in....
