OIL PRESS GOOD BUT NO OIL TO ROCKERS !! I just finished engine rebuild on 06 trailblazer SS 6.0, I have 45 + psi oil pressure at idle at dash gauge, and by testing pressure manually at sender location on block with my snap on tester/gauge but no oil visible at push rods/rockers!?. I realized this, due to test firing before completing installation, in fear of damaging engine i've only run for several short periods of time (seconds) after reviewing oil gallery schematics can't figure how this could be !? I've rebuilt many many engines in my 40+years, mostly euro/asain but a few domestics as well along the way!, hoping one of my GM wizards out there can set my dumb *** straight !? PLEASE HELP !!
