Bostitch Compressor never gets to cut off pressure?
I just replace the valve head with a newer style head from the CAP60PB-OF (mine is the CAP60P-OF) due to a broken valve flap.
Now it gets to about 128lbs and stops building pressure but keeps running.
The piston ring appeared to not have excessive wear.
Sounds as though you might have a gasket issue, Shawn.
Did you replace the gaskets when you replaced the valve plate?
If not, you likely need to. If so, you may have a crimp or weakened area that lets go when the pressure gets to the 128 PSI, and then the air just cycles back and forth in the head.
