recently rebuilt the cylinder head. Removed the entire engine -- inspected the bearing and cylinders. Had no history on the condition of the engine. Found bottom to be fresh. Valve train worn. rocker busings, shaft, rocker arms all replaced.
After reassembled -- oil pressure is lower than I remember. 50 psi cold 20 psi hot -- little change from idle to 3500 rpm when hot -- Flow to top end is low
Ideas as to the best place to look for the problem?
Removed oil pan to inspect --
Oil pump is good, main bearing clean, no debris found in the oil pan.
