Hello all I have a new to me RV7 with an O-360 the engine last had an overhaul in 2001 and currently has about 900 hours on it. During the last two oil changes i have performed i noted small particles on bronze and copper colored metal in the filter paper. Both times i did an oil analysis and it showed no abnormal wear metals in the oil. The oil suction screen is also completely clean. The material im seeing is not magnetic. Im guessing if i collected the material it would not be more then a 1/4 teaspoon based off what im seeing, and no pieces bigger then a broken pencil lead.
I have sent the pics both time to my mechanic and he has said no issues and this can be normal, but it still bothers me. I drained he oil today im seeing what looks like glitter same colored particles, my mechanic also said this is normal for high time engines.
Is this normal? and if not where can i begin investigating to find a cuase? what produces "copper" color particles in he engine?
