Help Me Diagnose Video Below
Built LS1 (low mile build)
48psi oil pressure idle
Right bank has developed a tick recently
Reset lifter preload with no difference. None of the lifters felt collapsed.
Should I pull the head off or am I paranoid?

Give it more time. Being a fresh build, a piece of grit or foreign material might have gotten in a lifter and could flush back out. Or an air bubble went thru the system and found a lifter. Could be any odd thing that could happen during break in.

Sorry - should have been clear. This is not a fresh build. Low miles, but driven hard.
It’s a royal pain to properly set up that system. Non adjustable valvetrain is setup with pushrod length. Those adjustable height rockers make this a tough setup. I’d play with the rocker bolt adjustments. Sounds like one on bank 2 is just lashed out instead of preloaded.

I didn't take a good look at the rockers and pushrods on the passenger side so I think I will pull those again and inspect/readjust. Going to change the oil as well. Will report back.
