Metal on oil screen

[Ted Waltman]

Is anyone on the list using an oil screen with their radial? I have a
set up made by Aviation Development Corporation, link below, which is
great in so far as one can change the screen without having to change
the oil.

I posted two images of the oil screen at 111 - S/M Engines.

I have 110+ hours since new on my M-14P engine. I've cleaned the screen
every 5 to 10 hours or so, each time noticing bits of very tiny (mainly)
aluminum (since a magnet doesn't pick up much). For sure, if one had a
standard oil filter that they cut open, one wouldn't see such fine bits
as one can clearly see with the screen (so this is a major plus to
having the screen).

The other day I took off the screen and saw quite a bit--40% ?--coverage
of the screen by small (tiny) bits of aluminum. One experienced A&P I
showed the screen to was very concerned; another said to just watch it
over time without any concern.

Regarding radials, and the M-14P in particular:

- Do radials throw more metal than in-line engines?

- Are there any published guidelines anyone has seen regarding
monitoring M-14 wear, especially re metal wear?

- If anyone else is using an ADC oil screen I'd like to compare notes.

- Anyone have input after reviewing pictures I posted?

Thank you folks!
