>>8597315Alright I'm 99% sure you're having the same issue I did at one point.
See part #4 here? That's what cause my problem and made my o ring look like it was failing, there was build up in this part and no amount of flushing, etc cleans it because of the shape and size of the hole on the pointy end.
Take off that bolt part again (part #3) then remove part #4. Grab a cleaning needle like the brass colored thing in here:
