[@BoostLeakTesters]

excellent and thorough video!

[@Motorcarnut]

Very much appreciated!

[@mcfischer214]

Is there a difference for this test between the pneumatic wastegate and the electronic wastegate

[@Motorcarnut]

No, wastegate has nothing to do with the test.

[@edwardcamis9795]

Thank you for the excellent video. Is it normal for air to come out of the valve cover opening during the pressurization where you removed the vent hose?

[@Motorcarnut]

The vent hose is blocked when pressurized. Yes it’s normal for a little air to be coming out of the valve cover oil fill.

[@gottgaame]

@@MotorcarnutI see quite a bit of oil in those suction turbo side is that normal?

[@Motorcarnut]

@@gottgaame No it’s not. Vacuum pump is failing

[@gottgaame]

@@Motorcarnut ok thank you

[@user-ut6zh6tt2i]

Hi, in your video, the leak in my n20 is coming from the engine port from the small hose 1 and 3/4 inch in diameter that was taken out. I followed the same procedure as in your video. What would be the cause of the leak. Thank s for advise . Hector of Canada

[@Motorcarnut]

What hose you talking about? Where does it connect to so I can understand which one you are talking about?

[@user-ut6zh6tt2i]

It is the vent hose taken out, the port of it is the first leak that is very strong. Thanks

[@user-ut6zh6tt2i]

and I can smell gas from that vent port

[@Motorcarnut]

@user-ut6zh6tt2i can you send a photo or post one on your channel so I can see?

[@user-ut6zh6tt2i]

Hi i sent a picture in ur instagram. The port with green O ring is the one leaking heavily
