MSD dizzy vac mod failures

Anyone having problems with MSD dizzys vacuum modules? Over the past 10 years or so I must have lost 6 or 7 of them. I cut a couple apart and even sent them back to MSD but they didn't have a clue. They did send me a replacement.
The diaphram is pulling loose from the crimp around the edges. No other engine problems, doesn't use oil, not finding anything in the module.
Only getting about 15" of vacuum at idle in neutral. Others must be having this problem.

????????? I'm pretty sure they are made in China
