IAW Champion AV-6R, I cut open and inspected the oil filter, Champion CH48110-1, on the O 360 A1A engine in my RV6. I picked up some metal with a magnet in the plets of the filter element. So, I went on to rinse the element out in solvent and this is what I found. Its about 1/16th of a teaspoon of fine metal granuals and slivers.
Engine has 200 hours SMOH accomplished in July of 1999. First ran in January 2010. Talked to the engine shop that overhuled the engine, consulted Mike Bush's articals, as many AP/IAs as I could find, local experts, and Lycoming SBs.
Responses range from "that's a lot of metal" to "check it again in 10 hours."
Most likely cause "cam or lifters."
I'll update the thread when I recheck the filter.
