I am in the middle of replacing some PCV parts on my wifes 02 Passat AWM. I was cleaning the various hoses behind the intake manifold along with my suction jet pump. It looks to be in good shape. Air only goes through one way (see first picture) like it is supposed to, but I'm not sure what is supposed to be happening with the smaller line coming out of the bottom (first picture again). When vacuum is applied to the pump, and the air flows through the pump, following the direction of the arrows, is air supposed to go in or out of the bottom line? Mine does neither. I'm assuming it is supposed to be sucking in as the line that connects there comes from the breather valve.
The red arrows indicate the direction of airflow. Can anyone tell me which way air is supposed to go from the bottome line? (The green or blue arrow)
Here is a cutaway view of the pump. The area circled in yellow seems to be clogged up on mine. Either way, no air moves through here. Again, the red arrows indicate the direction of airflow
Does anyone have one of these pumps handy that they would be willing to suck on to see that happens? I'm sure everyone on here would appreciate it.
