4 inch boost leak tester.

Well the PVC rubber coupler just isn't cutting it. They either blow off the cap or blow a hole in What have others used for a 4" boost leak tester? I'd hate to spend 60 bucks on a 4" t-bolt clamp and silicon coupler.

Do you suspect a leak at your turbo? Otherwise, just put a smaller one on the IC pipe.

Wow, coulda had a v8, didn't even think about that, durrr. The compressor cover is leaking from the back side so the turbo has to come out anyway to re-seal it. Thanks alot for smack in the head .
