I agree Bob, and I didn't worry about it either, until the performance started to feel a bit poor and our engineer found that one or two of the valves were not opening correctly and found a (very) few bits of metal in the filter. Ended up replacing almost everything inside except the case and the mags!! (IO360) The trouble is it's insidious as you can't see it. The camshaft was not pretty when it came out! Now have an engine dehumidifier fitted via the breather when it's in the hangar - hope that makes a difference.
