Cp3 knock

[DMAX497]

I was messing around with my truck today. Did a 4wd launch and heard a slight faint knock. Truck runs soooo smooth and not missing or anything. When I put my ear close you can hear the dual cp3 pump. And if you put your hand on it you can feel it.

Did I just blow this pump up? Should I park the truck?

Did you ever get an anwer? My CP3 is knocking on my dual pump

Yes, I blew the pump up... Get it of ASAP so you don't take out your injectors.

Thanks for replying, Mine would only knock at startup with stock sticks, now with 100s it knocks constantly! Im going to remove it tonight

It sounds just like a rod knock, or piston slap on an old LT1, coming directly from upper CP3.
