    Internal DV problems on Z20LET

    Hi guys I think my internal DV is ruptured again, this is the second time I will be replacing it - I'm not surprised though as I did replace the diaphragm with a none ruptured one that came off a busted turbo unit from a z20let before - that was a stroke of luck - but now i have to go another route and I'm looking for something that's gonna last this time at least without breaking the bank -

    What do you guys recommend? Thanks in advance.

    The easiest way to test if your OE DV is working is by taking off the pipe running form the OE DV leading to the rear BCS and sucking on it, if there is some sort of suction like for instance if the pipe gets stuck to your lip it means the DV is still working right? But if there ain't any suction at all it would mean the DV if very likely busted? Correct?
