oil pressure drops at high speed
i have a tahoe its a 2001 5.3l i can drive it around town all day no issues...
now when i get on the highway going 70 or even like a state route going 55 it
takes it a little bit like 25 to 30 mins of driving at that speed oil pressure drops
down to 20 i hear ticking like a lifter i pull over shut the car off then wait 2 to 3
mins ticking gone oil pressure is back up and 25 mins later it does it again i
replaced the oil sending unit and it still does it im stumped on this
