Yesterday in my post flight inspection I noticed my alternate air door (vertical sump FAB) departed the aircraft, screws and all! This lead me to pull the plugs for a FOD inspection. What I found does not look exactly like FOD to me but it has me wondering if I am leaning to the point of detonation. The erosion on the piston head has be concerned. I have posted two photos 1 for scale and the other a closeup of the erosion.
Here is the closeup
The engine has around 150hr SMOH w/chrome cylinders and using a quart every 6 hrs. Is this normal erosion?
