'Anyone added an air/oil seperator to their Ranger powered F24? I am
getting oil on the belly nearly every flight and want to eliminate
this. I'm sure someone has added the sperator and wondered which one
provided the best results. I'd also like to see a copy of the 337 for
the installation. Thanks for your feedback.

Steve'

'Steve,
You may want to start by putting question 3869 in the message search
box and follow the thread on a previous discussion in 2005. Some
owners do a separator, some don't. I have an air-oil separator for
the vacuum pump system, but not the crankcase vent system. That's
the way my Ranger came to me. I was able, however, to cut down on
belly oil by doing a number of things. I changed the routing of the
crankcase vent tubing (re-bent it actually) so there was a definite
up hill slope starting at the breather outlet. Even while the plane
sits in the three point position it has a slight upward slope. That
helped. Next I cut some of the tubing off where it protruded down in
the air stream at the bottom. It also use to have a 45 degree cut
at the end that faced rearward. I cut it off straight with the air
stream Also about 12 inches up from the end I put a small vent hole.
I think they use to be called ice holes. Anyway the whole idea was
to eliminate as much draw as possible. I still get a little oil, not
much, but to me that's the nature of??.. the beast.

'Thanks Tom. I will use your tips and review my installations to see
if that can help reduce the loss. I'll also review question 3869 to
see what it says. Thanks again for you input.
