Oil from oil cap

I have a 2012 Golf R 6 speed, 92.3k miles on it. It has the APR Boost tap connected to a gauge (from previous owner). Anyhow, I helped jumpstart a friendís car a few days ago and noticed the line going from the tap to the gauge was a bit in the way of the plastic battery cover so I had to move it. Didnít think much of it, thought I returned it to the right place. A couple of days later, I notice I got a bit of oil spray from my oil cap. I know thatís commonly an indicator of a bad PCV valve. Itís happened on two drives in a row so I thought it must be completely locked up. I get home and try the test of removing the oil cap while idling and the car cannot idle when cap is removed, there is a noticeable vacuum. My understanding was that if the PCV is bad, then it would idle as normal without the oil cap. I have an APR Catch Can on the way to eliminate this issue for good but my car is my daily so I wanted to post in here to see if anyone had any advice or insight as to whatís going on or if Iím on the right track. Maybe if youíre in the Austin/San Antonio area and have a spare working PCV valve to hand off any help is appreciated

I did this post a couple days ago, it maybe of help you, to check the PCV diaphragm. You may find one at your local Autoparts Store.

Good luck!

EDIT: They all seem to use the same part but I could be wrong, as I never seen a Golf R up close.
