SOURCE: oil pressure gauge stays at top, about 80 psi, is this normal

80 is on the high side for those... possibly a sending unit issue

That eliminates the crankshaft and camshaft position sensors. Have you checked the fuel injector itself for an open winding or stuck valve plunger? There should not be a steady 12 volts to the injector--if good injector, it would be spraying fuel steadily into the throttle body. But at least the engine should try to run if poorly. Take the injector out, dry it off with air, and intermittently apply 12 volts to one terminal while grounding the other. You should hear a click from inside every time you touch 12 volts. If not, replace it. If it does, it may be plugged with debris. Try blowing through it in reverse with compressed air.

SOURCE: 1991 chevy S10 blazer fluctuating oil pressure

I assume from the year it has high mileage. With mileage comes wear in these engine's bearings allowing oil pressure to drop because of the excess clearance between cam and bearings, also the crank and bearings. When the engine is hot and idling the oil is thinner and goes by the bearings quicker. If you have good oil pressure while driving, I'd leave it alone, maybe use a thicker oil or some lucas additive. My 89 does the same thing sometimes in the summer, but don't remember it doing it this summer. I use Mobil-1 and an AC Delco filter.

Is there a oil safety switch on 2002 Chevy s10 zr2


You have a oil pressure switch which is located by the oil filter,it is screwed into block,just removed electrical connector,get wrench and remove.
  • When the oil pressure is either high or low it will either turn the oil light "on" in the dash or move the gauge to the extremes
  • Undetected high or low oil pressure can result in internal engine damage and/or gasket leakage. Here's a picture of what it look's like.
