knocking after cam install.. camshaft-238/242 .581 .581 113lsa comp cam
livernois 7.400 pushrods
livernois valve seals
patriot gold dual valve springs/retainers
i just installed the camshaft today everything went smooth camshaft is dead on i marked the chain in 2 spots, i have done over 100 hemi swaps so i was sure to get the timing dead on..
either way its a loud knock and i can hear it on what i think both sides like a lifter..
5 monthes ago i was driving the car and it just started doing this same sound out of the blue.. then it went away after about 5 minutes of driving..
also when i pull the fuse for the fuel pump and crank it over with no fuel and just the starter it makes no noise..
any ideas?
i have a vid coming

I see the problem in your sig, you have a flowmaster.... jk could be a rocker arm not torqued all the way or could be a bad lifter i guess. Did you replace them?

thanks for the tips guys.. i never unplugged the injectors..
i did install brand new seals from livernois they were just a press on type seal went on pretty hard..
also im thinking now that maybe the pushrods are to long..
cam is ground on the xer lobes..
yes stock rocker arms also..

I know this doesnt help you. But your not alone!
Just put a TS cam and dual springs in my camaro.
I had a BAD noise 30 seconds after I started it. Like a squeeky knock. I took the valve covers off. Found nothing wrong. No issue turning over by hand. Put it back together, started it. Noise came right back.
While I was listening to the engine it seemed to come from center of the block (Lifter?) well after about 30 sec it went away?
let it idle to full hot twice and its just as quiet as can be...
