2.5 turbo common block
just noticed that above 3k stock oil pressure gauge takes a nose dive and would probably go completely low if i held the throttle down
no visible oil leaks, no oil on the ground, dipstick shows mark almost at 75% to max
no audible clicking or knocking noises
compression test yesterday revealed 130 130 140 140 and spark plugs looked great
tried wiggling oil pressure sensor connector while idling and watching gauge...gauge stayed solid
checked all rod bearings and 1 main bearing a week ago (engine was apart) and they looked okay
piston and rings for cylinder #1 were replaced a week ago
i know for sure that gauge did NOT do this at least a month ago
what could i have forgotten to do? this is the 3rd time ive taken this engine apart so im not DUMB...
