I am looking for any information concerning the oil breather line from the Christen oil separator. From pics it looks like builders have used aluminum tube or aeroquip hose. I assume aluminum tube is lighter.
First question is what size tube?
Second, in Scott Rodriguez gallery, he has photos of a Christen Eagle aluminum blowby exit tube he built for his plane. Seems pretty slick. Scott or anyone, can you tell us how you made it? Here is a link to the photo-

On Yellowbird, there is an opening in front of the tailwheel for the blowby tube to exit. That link is here-

I had thought this might be a good exit for cooling cockpit air to exit the plane as well. For cooling air to come in it seems you would need an exit path other than leaks. I suppose the downside is this is an easy path for bees or other insects to enter your plane. Any opinions?
cheers,
Jim
