Oily fluid in pressure sensor line?
I switched my boost controller & gauge from being hooked to my FPR, to my pressure sensor line. When I took the pressure sensor line off I noticed that there was some oily fluid inside the line and into the pressure sensor itself. I blew it all out and put it back, but I want to know why/how that crap got there. It is under vacuum and I tested to see by unplugging the pressure sensor while idling and felt suction at the hose. Any ideas?
I also noticed there is no pill in the pressure sensor line, what are the problems; if any, with this?

The only thing I could guess is gunk from the PCV system is making its way into the line. Where's the boost sensor getting its vac signal from? The stock location?
The pill for the boost sensor smooths out the pressure signal to the ECU. It helps avoid stumbles and it'll make the boost graphs in your Rtek logs cleaner.

Yeah it is hooked up to the stock location. I just don't see how it stayed in there. I had driven the car about 1 hour before I started working on it.
