Default fuel injectors ticking...

is this just meaning the injectors need to be replaced? or is there more to the story? or what more can it mean if the injectors are ticking? the ticking is at its loudest at 3000rpm when driving. as the car heats up the ticking dies down a bit... ive tightened the rockers and everything else it seems to try to figure out whats ticking. all thats left is the injectors

How exactly have you traced this down to the injectors? Fuel injectors don't make much noise at all, although if you get really close, you can hear them pulsing.

You've checked the pushrods as well? I'm just having doubts that injectors could be making that kinda racket, especially that you could hear at 3000 RPMs.

well when i pulled the valve covers off and adjusted the rockers i checked the pushrods and they are all good. i narrowed it down to the injectors when i could still hear the noise after i did the valvetrain adjustment, and when i touch the injector connectors (mostly on injector#2) i can feel the ticking going along with the sound.

i even checked for an exhaust leak and nothing, the ticking is coming from the top of the engine.

Do LT1s use the same style of injectors as an LS1? I only ask because I have my old stockers from my 2002 LS1 just laying around collecting dust.
