Boost leak test

[Kegsandeggs]

So I made a boost leak tester out of an extra intake coupler I had. Problem I'm having is how to plug the pcv/bpv holes in the v band so I can pressurize the system. Any ideas would be greatly appreciated!

Little, tapered rubber plugs might do the trick.

I just don't want to drop anything into the turbo

From what I am gathering, you plan on putting the coupler onto the turbo inlet. Is this correct?

My boost test will be only post turbo. I was going to have a plug that was the same size as the turbo outlet, and a plug that was the same size as the throttle body.

I was then going to put a schrader valve in either one. Then I was going to test for leakdown by using my tire inflator that has a gauge built into the unit. See image below.
