So my left engine on my Aztec seems to be throwing oil recently, I am on mineral oil as was breaking in some new cylinders, have around 24hrs on the new jugs.

I originally thought the oil was coming from the breather tube (3/4 inch steel tube just inside the inboard cowl flap, however noticed it's actually dripping from the little steel tube (about 1/4 diameter) that protruded from just in front of the cowl flap. I'm wondering if I have a plugged hose or something

I do have the Air/oil separators on the engine,

My right engine doesn't do this

I haven't looked at my manual yet to see where this drain tube leads too

Any ideas?
