Doctor,
The breather blows pretty good when the car is hot. I checked it when i did the valves and it is clear. The hose is clear too so that ain't it. I wish it was that easy... Was it you that had the leaking wastegate also?
I'm betting that this is a fairly common failure that never gets diagnosed and folks just live with the leak thinking it is a turbo seal or seomthng big that has failed.

It was your post that got me really going on this. I find it hard to believe though that ther could be that much suction with a new air filter and the tube off the connector to the front duct.
I searched my parts file and see a listing for both the check valve (617 018 00 29) and a part called a "clamping sleeve" (007346 020001). Both combined appear to only be about 16.00 from the dealer but I have no clue what the clamping sleeve is. It is displayed along with the check valve though so maybe it is what holds the valve into place.
What has me going is the fact that the MityVac tests my valve as good but yet under certain conditions it obviously is not. Theoretically a valve like this would only open one way so the weight of the oil on top of it would open it but why mine would test good yet allow oil to climb that tube is a true mystery to me. Especially when there is no oil being introduced via the tube.
If can think of any other tests to perform, I am on a mission and am willing to try just about anything to figure this out as long as I can do it.
I love driving this car but I cannot leave a puddle on every driveway that I visit. If I don't figure this one out I'll probably sell it but I hate passing problems on to another owner (like all the POs have done to me)...
If you do yours please share the experience. If I had any indication how to deal with it I would probably go for it this weekend just to see. $16.00 I can afford to throw into this, a new turbo (which is what I thought I needed) I cannot.
