I come across many RV's whose operators forget to check the oil screen on the engine. It should be checked at least once per year during the annual or whenever the internal health of the engine is in question. Here is a picture of one I removed from an RV10 yesterday that should drive the message home. IO-540 with 10:1 pistons and only 600 hours. I don't know when the screen was last checked, but clearly there is lots of blowby. All of the chunks were carbon, the screen was about 50% blocked, with one cylinder at 48/80 and 54/80 and all of the leakage going by the rings.
