My Suburban is sucking oil into the airbreather (K&N) and I mean alot of oil, the breather had about 1/4 of a quart of oil in it. This is a TBI so the breather is similar to a carb breather. It is pulling oil through the pcv valve and the tube that goes to the breather from the other valve cover.

I took the hose off on the one side and have it hanging loose and it is putting out a small amount of oil from that tube but not much.

Any body have a clue on this one? Has anybody seen anything like that before?

I have about 5000 miles on the engine.
