Lynn,
? Built a separator, 5 vane 6" tall and? insulated it.Last 2 hrs have collected
1"of moisture in the catch bottle but no oil.Now I can keep tabs on oil consumption.Finished
a 4 vane 4" tall separator that I will install this weekend.They
look weird but it's effective.I'll just keep making it smaller until it can't
trap the oil.Here's a picture.

It may be the difference between your Kolb pusher, and my enclosed-engine tractor
Kitfox, but your plumbing sounds really convoluted! This oil collection business
doesn't seem to me to have to be all that complicated, but of course in
an engine-exposed environment things will be different.?
Keep us posted will you, Gary??
