Low Oil Pressure.

[Suffolk GameServer LAN]

I read all the past post(s).
I'm gonna go out on a limb and say if he checks the relief "valve" by the
filter:

"I've tried inspecting / swapping oil pressure relief springs and pistons
and
also replaced the senders in the block, but the oil pressure still remains
low.  Since everthing is new on the engine, I'm suspecting something isn't
allowing for pressure to build up."

Could it just be the thin like (5 -30W) oil and a cheap - sounds like "Cram"
filter?

When I test ran one on my 10V the 5bar was more like 3 bar at highway
speeds,
so I swapped out for a Mann and got 5 bar that samwe day.
