I have a 2000 yukon denali with the 5.7. Oil pressure it at around 40 at start up once it gets up to operating temp the gauge drops to zero when at a stop. Goes back to 40 while driving. I have had the oil pump change the screen changed and the oil pressure switch changed and it continues to do it. Truck has 105000 miles on it. Also does not make any knocking sounds from engine slight lifter tick is all.
