brought my jetta in and they told me oil had gotten into the turbo lines. they said i should replace my pcv valve. i called the VW parts store looking for the part and they said there isnt a set PCV valve on the car. he told me i should buy a PCV Breather Hose. does that sound correct? how can i tell if that hose is in fact bad? the car was brought in becuz ive noticed a little loss in power. here is a picture of my engine, can anyone give me more information and point out where some of these parts are?
