Oil return line
in 912 / 914 Technical Questions
3 years ago
I have been chasing oil leaks and blown main seals on a freshly overhauled and modified 912. newly installed in a different aircraft. Whiling working on the return line we noticed it is only about 7/16 ID and my kit fox is 1/2 inch. Fox runs great no leaks in 12 years it is factory built and I have found they really do their homework. The fittings are also smaller.
could this cause a higher crank pressure especially on this high HP engine?
why does one 912 have a 1/2 hose and fittings then another have 7/16? What is he correct size?
