so in your pic where do you put the pipe? i made one from a bean can and put it on the turbo inlet pipe pumped it up and heard quite a loud hissing sounded like it was coming from the block itself like a crankcase breather or something so just gave up.

You do need to block off the crankcase breather at the hockey-puck. I also block off the small hoses coming off the throttle body and test them separately
