LSvtec w/ endyn rollerwaves and eagles. The block was milled 25 thousands and the pistons stick out of the deck 4-5 thousandths. I'm using a thick headgasket.

Not when i start the car, or let it warm up. but after its all warm i start to hear one click coming from the head. If you get down and put your ear next to it its either coming from above the #1 cylinder or down by the pullies. Its pretty loud and very consistent. Once i start to accelerate, i can no longer hear the noise.

I have checked my valve clearances 3times, and every time they are perfect.

 

is it a loud clicking or a faint clicking? what size injectors do you have? A friend of mine had the same problem but it turned out to be his injectors where clicking really loud

 

Yea if you have dsm injectors they are loud as ****. They click like no other.

 

its really ******* loud. i'll go move the injectors around and see if that changes anything. (where the sound is coming from )

stock injectors. still waiting on the boost

 

moving them around wont do much.... but if you take a long screw driver and place the metal end on the injector and put your ear on the plastic handle you will be able to tell if its the injectors
