werid noise

[ChevyDieselLLY]

alright when my truck in idleing there is this werid noise like something is loose and it about to fall off. but as soon as i give it a lil fuel it stops. Dustin (othrgrl) thought it might be injectors. i did just put on a 2nd fueler could this be the problem?

hopefully this just means i need to build the motor that much sooner seeing houw the water pump is going as well.

thanks for the input.

dude noises are so hard to diagnose over the web , i would have to suspect the dual cp3's just because the noise started after the went on , maybe a bad reg on one of them ? have you checked balance rates ? what about loging desired rail pressure VS actual rail @ idle ? just some idea's

alright thanks for the ideas i will check those things out.

I would say its probably fuel pressure related too. I wish i wouldve got a video of when i first started mine but forgot to plug in the FPRV. It sounded like top fuel dragster.
