Do not undertighten the vacuum pump piston nut
I rebuilt my leaking vacuum pump but failed to tighten the bolt enough due to stern warning against over tightening. I used blue loctite but the nut didn't hold so the piston bolt went through the aluminum vacuum pump cover.
Have fun! Mick

Sorry too hear about that The first one I did ripped the diaphram in about a month. (too tight) You probaly dont have a torque wrench that goes that low, like me. I cant remember the number, but it is below my torque wrench. I was considering the red thread lock next time.

My solution was to just replace the entire pump from a junked car at the wrecking yard. I had sunk $80 into the rebuild kit when all I really needed were the 3 check valves. I swapped the check valves from my broken pump to my newly acquired wrecking yard pump and bolted everything back up. Worked flawlessly and I didn't have to worry about under or over tightening that nut. The used pump only cost $30 from Pick N' Pull -- should have gone this way to begin with!
