3.8 lifter problem

I have a 2003 chevy monte carlo SS 3.8 .I just finished installing a atk motor from advanced auto parts.the problem is the lifters are noisey and sound like they are not pumping up.

I primed the engine before starting.engine has normal oil pressure but on initial start up the rockers and lifters are noisey.Maybe when this motor was built they forgot to install a oil gally plug?I let this engine run for about 10 minutes and noise is still there.LOW OIL PRESSURE LIGHT CAME ON AND OIL PRESSURE DROPPED TO 0!!! I shut engine off and started it back up and oil pressure returned to normal???? WEIRD!!fI had a simuliar problem with a ford small block and it was a oil galley plug.Anyone on here had a problem like this with their 3800? i paid $1900 for this motor and i am a bit upset about this problem!! I am thinking about sending this motor back..

Any input would be greatly appreciated
 


Was this engine a short block, or a long block?
I would hook up a mechanical oil pressure gauge to get accurate numbers. Pull the valve covers off and look for oil flow.
 
Well engine has oil getting to the top of the motor.Motor is still clicking.I could not get my old knock sensors out of the old engine.Maybe its pinging because i dont have any knock sensors?
