This is a video of a pressure test with the PCV valve removed (tis fooked!), the pipework is blanked at the turbo outlet, the pressure gauge connected to the charge pipe and the supply fed from where the PCV valve connects under the manifold.
Both breather connections have been removed as well as the oil cap.
The gauge range is from 0 to 1 Bar, there is a small amount of leakage coming from the removed breather hoses indicating that the air is passing through th block and out through the breather hoses, when this test is carried out with the PCV valve in, it loses pressure much quicker.
New one ordered!
Does this all sound about right? or could I be missing something?
Just to add, the video starts with the system at about 5 psi, I then open the valve until about 10.5 psi, then I close the valve, the rate at which the gauge drops is the rate of leak I have, but I dont know if it is a good one or a bad one?

I would say that has been leaking.

Turbo gaskets, look ok.
