Ive got this clicking noise coming from my new engine. Its high pitched, and kinda sounds like the button on the bottom of those snapple caps. Anyway, I tried pulling spark plug wires to eliminate the bad cylinder, but the sound neither increase or decreased in intensity. I removed the oil pan, and checked the rods, there was no abnormal play, they felt like they did freshly built. And if I put a scredriver to my ear, the sound seems to be coming from the head and not the block, Its best heard by the timing belt.
I think it might be LMAs since im runing b16a1 LMAs with crower stage 2 cams. Can someone tell me what bad LMAS sound like? Like a snapple cap? Or is this a spun bearing? I guess I should have taken the rod caps off, but it seems impossibler from the bottom of the car, what tool could i use?

 

oh, and this noise is louder at idle. and then becomes inaudible as the RPM's go up.
