Vice LPR Creep
Hey guys, I have a Bob Long Vice with one problem. The LPR Pressure creeps. I have the tester and I've set the LPR to 65 PSI and it stay there. Once I start to shoot fast in semi, the LPR gauge slowly rises to about 80 to 85 PSI. I have taken apart the LPR, replaced and lubed (DOW 55) the three orings on the outside of the Housing and the LPR Piston oring. The LPR Pressure gets from maybe 65 and it rises to 75 slowly. I've also already put Loctite on the adjustment screw so it can't slowly unscrew. I was wondering what else I could do to fix this. Thanks.
Edit: I've also cleaned my HPR.

will it creep when you're not shooting?
Does it go back to the original setting, or stay high?

Yes, it creeps when at a stand still.
When I shoot it, it goes back to 65 and slowly creeps up to 75 or so.

I Dont Know If This May Help But Can You Also Check Your High Pressure Setting And Also See If Your Hp Reg. Creeps Too.

Ok. I checked it too and it works fine.
I've already talked to BLAST so I'm just going to send it in to replace the Schrader Valve.

This is exactly your problem. I had the same exact thing happen to me a couple of weeks ago. Just call Blast and they will tell you what to do.
EDIT: Haha i just read your last reply. Once you get it back from Blast it will shoot like brand new

its sounds like you have the same problem. i would first check and see if rebuilding your hpr helps but i think its the lpr's schrader valve thats bad
