total engine rebuild. New camshaft with new bearings correctly installed. .010"/.010" grind on crank with .0025"/.0025" clearances respectively. Melling high volume/high pressure oil pump with new pickup tube/screen. Block cleaned and magnafluxed. Oil pressure for cold engine: 55-60psi at 1300rpm and 40-45psi at idle of 950rpm. Oil pressure at operating temperature (190 deg F.) drops to 35-40psi at 2000rpm and 8-10psi at idle of 950rpm. No lifter noises at all. New mechanical liquid-filled oil pressure gauge installed at the filter area with an additional mechanical oil pressure gauge for inside the car. Both gauges read the same. When engine rpm goes up the oil pressure goes up quickly when cold and when at operating temperature. The oil pump and pickup tube/screen have since then been replaced with no improvements or changes in oil pressure. The liquid-filled gauge has been added since that repair with no differences between the gauges. The engine runs very strong and has no abnormal noises. No oil leaks at all. No oil in coolant or vise versa. Oil level is full and is 20-50wt. Valvoline oil. So is the Motorcraft FL1-A possibly defective by bypassing pressure or could there be an internal leak in the engine from one of the oil gallery plugs causing this loss in pressure ?
Thanks!
