Ls3 tick
Hey guys brand new crate ls3 holley terminator x. Tuned by Andrew. Everything was great until i started break in procedure according to gm paperwork. Holding at 2000 rpm it developed a ticking noise
It has tsp stage 3 cam with springs and 7.4” pushrods.
Also oil pressure while idling goes from 28-29 psi cold to about 24 psi when at operating temp.
I am using driven BR30 oil for break in
Any input will be greatly appreciated

04-24-2021 #2Do not run it again, any potential metal shavings will destroy it. But first, you confirmed that it’s not an exhaust leak? If it’s not, I would start by checking rocker arms. Find a loose one, then diagnose why. To me, it didn’t sound too deep down, like a rod knock. Also some like to cut open the used oil filter to make sure there are no metal shavings, although I think you may see some normally upon break-in.
