Does a ve pump make alot of noise when they get near the end of there life? I've got some kinda noise that I can hear inside the cab when I'm cruisein an it sounds like slack in the valve train but I checked the lash an everything is alright plus the noise goes away when it's idling an when there's a load on the motor. I recently bought a set of injectors an there set at 250 bar so I was thinking maybe that little bit of extra strain is gettin to the pump or could it be a timing issue an my pistons are slapin down against my rods.

Give me some ideals guys an thanks in advance
