I was hoping someone could help point me in the right direction.
During annual I pulled the oil screen and found one 0.315 x 0.157 very thin shard of non magnetic piece of material. it almost looked like a thin sliver of aluminum. Interestingly I cant find anything in the filter although the oil that was left in the oil screen seemed grayish like there is aluminum "dust" mixed in the oil, maybe it is other contaminant (lead deposit?)
Have not send the oil in for analysis yet. The hartzell C/S prop was recently overhauled (5hrs ago) and the engine is running great and is 144hrs old.
Engine is an mattituck M1b IO-360.
Anyone seen this before? what can cause one lone sliver of silver non magnetic material in the oil screen? Can it come from the prop? What is the next best step? teardown?
Thank you so much for your time, any advice is appreciated.
