Does anyone no if this is a one way valve as i can't get my car to run right still!! I've done a boost leak test no leaks changed plugs coil packs DV etc it just ticks over a little lumpy and the turbo is on and off when I'm booting it?  When I put my foot Down the turbo boosts then it fades then it come back? The valve about is completely clear and I was told it shouldn't be like that plz need help ASAP so I can sort it cheers guys   Its a crank case vent valve ivebeen told if it f..ked then I will loose boost and have bad running if some one could remove and tell me if there's is one way if you blow into it?

I may be wrong but it's the check valve on the PCV that is one way, the hockey puck on TIP regulates the pressure and closes if needed.

I could blow through and air pass through that was with a brand new hockey puck from VW
