Got my new build running today.
Priming the pump with a drill gave me 70psi, and on initial start up, oil pressure was around 75psi.
I was breaking the cam in, running it at 2600rpm, and after around 15 minutes, oil pressure had dropped off to around 15psi. I shut it down to hopefully avoid damage.
All clearances were .0015-.002 on the rods & mains, and new cam bearings properly installed by me. It has a new TA cover, Melling SD pump with the 60psi spring in it.
I restarted it and idled it for a couple seconds to check oil flow to the turbo ,and there was some valvetrain noise, and the oil pressure gauge read zero.
I haven't dropped the oil or filter yet to check for debris. (I had to walk away from it for a while)
When building the front cover, the bypass valve was sticky in its bore. I cleaned it up, and had it moving freely, but if it stuck again, could it cause the low pressure?
I was running 10w40 with a bottle of ZDDP, and ZPaste on the cam.
