How test and repair VW / Audi 2.0T 1.8T PCV valve with an RKX upgraded PCV valve

You can find our upgraded PCV valve here: www.rkxtech.com/collections/p...
Testing for a ruptured PCV valve is simple! If you feel vacuum coming out of the top vent hole on the PCV valve cap your PCV valve has an issue. This vent hole is simply a breather to let the PCV valve move up and down freely. You will never feel / hear vacuum from it when it is working properly.

Excellent demo! I’ve watched a dozen videos on this topic, and you’re the only one… to show how to perform the finger vacuum test. Cheers!

Removing this cap is the biggest pain in my ass rn

Will a PCV diaphragm from a MKVI GTI work? They look the same. I ask because I have a spare laying around from when I used to own a GTI

[@UncleSamGR]

I have some oil leak around this diaphragm round cap you pop off. Should i check it or its not a problem?

[@spelunkerd]

How much vacuum is normally present in the crankcase at idle in these turbo engines? Is it enough to cause the engine to misfire and nearly quit when the oil cap is removed? When the diaphragm tears, does the vacuum pump normally apply full vacuum to the crankcase, unregulated by the PCV diaphragm?

[@RKXTECHcom]

There is a good amount of vacuum inside the crankcase when this is working normally. These engines are sealed tight so removing your oil cap with the engine on will cause a missive vacuum leak essentially. When the PCV valve ruptures even more vacuum is applied to the crankcase and its typically really really difficult to remove the oil cap with the engine running because there is so much vacuum.

[@gardenstateflatlandb]

HOW DO YOU MAKE IT LOOK SO EASY WTF I'M BREAKING MY OEM CAP TO TRY TO REMOVE AND ITS IMPOSSIBLE

[@KeanuRiefs]

Exactly lol he made it look so easy while im struggling to pop it off. Any tips?

[@onurgns]

How the heck that hole opening there . Bc pressure ?

[@mrw1160]

Yes

[@mrw1160]

The pressure from blow by through the small gap in the piston rings will cause this to perk up when pressure exceeds a certain level

[@onurgns]

@@mrw1160 turbo engines requires that 6 k miles oil change . I do 6 k high quality oil. And also best to replace oil seperator at 80k miles

[@larsk7708]

I have p0171 code system to lean

[@FayazShaikh]

air blowing out of the breather hole is normal?

[@PerrosDeBox]

I have the same. Blowing instead vacuum

[@Mike-we3rb]

I got 2.0t and mine doesn’t have clips or the hole opening. It’s all just one sealed piece
