Just wanted to confirm if I do it right and if what I witness is ok...

The setup:
- PRV (hockey puck) valve (engine side tip) jammed;
- MAF disconnected and intake tip plugged;
- Oil cap removed to release crank pressure;

I've used EVAP connection to the tip to pump into intake.
Used a bicycle pump with external pressure gauge to pressurize the intake. It's the pump, that you hold standing with both feet on.

And... I can't pump fast enough to pressurize it, all I hear bubbles gurgling in the pan. Max I get is 5psi, which drops down to 0 in 2 seconds. I assume air gets past turbo seal into oil feed return into oil pan... Is that normal? I don't remember I had this in the past... And no obvious leaks can be seen.

Do I really need powerful compressor to test for leaks?

Thanks in advance!

Hi, If you haven't got a compressor use a spare wheel/tyre at 15/20 psi max.
Hoggy. :D

Thanks Hoggy, I assume pump isn't enough then :)

I think last time I was testing post turbo-throttle, that's why there was no gurgling...
