Sometimes
the large pieces don't show up using Spectrometric oil analysis. If the engine
has not been operated for some time the larger objects settle out of the oil and
often don't end up in the sample jar that you send to the lab.
I'm always looking for interesting pictures from
Lycoming or Continental engines that illustrate a failure or
maintenance issue for publication on this web site. Email me
