912 making oil
I have a 912 in a sling.
I have noticed the oil level rising and after last flight found oil tank overfilled by approx 350ml Sent oil to be analysed and came back saying fuel dilution between 4 and 8 %. No fuel evident on fuel pump drain line. The a/c is a low wing so no ways fuel can be running into carbs ?
Any ideas ? Got me stumped !
