Boost Pressure Tester Build Instructions
#21
Person could use this to check for leaking valve seats and cylinders. Course you have to remove all the rockers, but it will save a buck or two!

I have been doing this for years. A rubber or plastic cap over the turbo inlet Clamp it down tight then remove any pipe plug in the intake and run regulated shop air at 5-10 psi.Sometimes you have to roll engine over with a bar to keep some of the air from going out the exhaust. Soap bottle works great for finding boost leaks just watch the inlet cap sometimes she blows off with a bang.

This is the only thing I could make work for my 06. Everything was too friggin odd sized.
If you want to build one:
1x 3" 90* elbow
1x 3" 90* street L
1x 3" cap
1' of 3" PVC pipe
What you think will work for an air supply
BTW, all the fittings/pipe has to be heavy walled. Otherwise, nothing fits right.

Even for the one I made the normal pipe wasn't big enough, you had to use a fitting end to fit in the rubber hose.

i built mine just like this but what i found was that my bd boost elbow would leek off all the compressed air through a small machined hole in the side of it!! even with the set screw in which would "plug the wastegate" it still bleeds off air. is it spose to do this cus this might be my boost leak i have been lookin for
#29
yes the adjustible elbow is to slow the opening of the wastegate but not disable it all together. If you want to disable it take the elbow off and put a 1/4" pipe plug in its place just watch the boost and keep under 45 or so with a stock HG.
