The oil was free of any visible FOD, (sample sent for oil analysis), but when I washed the 3 filters I did find a number (maybe 15 particles per filter) of very small (barely visible) metal pieces. They were clearly ferrous (they stuck to my magnet). Should I be worried? The airplane sat for a lot of years before this run. The temps and pressures are all good, and the EGT is good. The spooldown takes a while (indicated not damaged bearings), but there is a noise on spooldown (almost like a clicking) below ~200 rpm, audible from near the inlets. I am concerned about potential corrosion/damage to the bearings from sitting, any thoughts? My current plan is to do another engine run, another flight (less than 30 minutes), come back, and drain the oil again to see if more metal has accumulated. Is this reasonable? Thanks!
