I just finished my rebuild last night and got back to it today to pressure test the motor and after about 30 minutes it drops from 15 psi to 9 psi. Do I just need to go ahead pull the motor back apart for a possible pinched seal or is there some things I should check before I do that?

update: one of my housing freeze plugs i just installed was leaking a little bit so hopefully it’s just that

 

Have you tested again after fixing the freeze plug?

 

sorry yeah I had some life stuff come up but yeah with the new freeze plugs it sealed up and didn’t drop pressure for an hour
