Banshee leaking oil

[adamson350r]

I have a 92 banshee that I am in the process of powder coating and getting new plastic when I noticed oil leaking from the back engine breather, a little blastic eldbow. I this normal, or has something gone haywire internally? The nose of the bike is slightly elevated.

I've ran through same problem. Head more n likely warp causeing blow by which in relates to a blown crank seal causing pressure to build up in trans case . Do a leak down test should show what's bad.
