Bad lost motion assemblies?
I have a freshly built a6 block/z6 head. It runs great but it has a pretty good tick coming from the head. The valves have been adjusted so I know it's not that. The tick happens at idle and under load, but when slowing down in gear there is no sound. I have great oil pressure so I'm not considering that it's rod knock, it's also too high pitched to be rod knock. I have spun plenty of bearings.

if its a wrist pin, im jumping off a bridge. that though was in the back of my mind, but i am really hoping it isnt.
i changed the LMA's for another set of used ones i had and the problem went away till it warmed up. before it would do it cold or hot.
i am assuming if the problem goes away with a plug wire pulled that means wrist pin huh?
the valve springs are good. i looked the whole valve train over pretty damn good

if its a wrist pin, couldnt i use a dial indicator and along rod on top of the piston through the plug hole to see if i can move the crank and the piston sit still for a few degrees?

i took a short video of it running and then realized i cant find a cord to connect the camera. im sure i have like 15 of these things and i cant find a single one.
it looks like i am going to pull the damn thing apart. this is what i get for getting used parts
