Okay, a few days driving around with the completed intake. I now get intermittent moments of boost, although it seems to depend a lot on how warm things are.
I have to put the car up to change the oil shortly and will be taking off the belly pan so I can inspect the turbo more closely. The last air leak I can hear is coming from inboard on the turbo, near the wastegate. I'm starting to think that something is cracked.
Any ideas on what to look for besides an obvious hole?
