Boost Leak Testing
I'm trying to do a pressure test since I've already found a loose coupling.
I've disconnected the line from the intake to PVC, and plugged it . As far as I know that's the only thing to do before testing.
But when I apply the pressure, I hear bubbling in the engine like the air is coming through the oil.
Is there something else i need to clamp off..or is there something wrong with my engine?

Go from intake boot to post turbo... There is always a valve in the head slightly open...

Still...how would there be a channel to something under the oil?
Do you hear bubbling when you test yours? and what do you mean "intake boot to post turbo?
Also I noticed on the write, were you blocking off the piping right before the intake (throttlebody)?
