SOURCE: 1999 bravada oil

check for coolant in the oil. remove the oil fill cap and look for a white milky substance. most likely engine damage has already occured because to have that low if oil pressure there is too much "clearance" between the bearings and the components they work with-(crankshaft,camshaft,connectiong rods). that vehicle came with dexacool coolant and it would shorten the life of the intake gaskets. they then would leak into the engine ruining the bearings over time. the skip can happen from lifters hydrolocked with the oil/coolant solution. take it to a reputable mechanic for an analysis......Good luck.......Scott

CHECK THE OIL PUMP SUMP TUBE O-RING. THEY COLLAPSE CAUSING THE OIL PUMP TO PULL AIR INSTEAD OF OIL. TO VERIFY OVER FILL ENGINE OIL AND CHECK ENGINE OIL PRESSURE. THIS IS A COMMON PROBLEM ON ALL NEWER GM V-8 ENGINES : 4.8 5.3 5.7 6.0

Need to know where the fuse is for oil sending unit on a 1998 Buick Park Avenue with a 3800 v6


There is no fuse for the oil sending unit ! Oil lite on , gauge not working ? Do you know what PCM five volt reference voltage is ? The PCM - engine computer supply's a stable 5 volt voltage to engine sensors . The oil pressure sensor is one of these sensors .
Engine Oil Pressure Sensor
The engine oil pressure sensor is a solid state transducer. The engine oil pressure sensor sends oil pressure information to the PCM. The PCM then transmits the oil pressure information to the IPC via serial data.
Engine oil pressure is displayed on the scan tool in volts. A low voltage reading indicates low oil pressure. As the oil pressure increases, the voltage level also increases. The normal range of the engine oil level sensor signal voltage is 0.5 volts at 0 kPa (0 psi) to 4.5 volts at 883 kPa (128 psi).

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.

What should the cold start oil psi and the 190 degree warm up oil psi be on a 2000 to 2002 gmc Yukon with a 5.3 eng


Different engines can show different values. Sometimes it is the sensor itself that causes the variation. The pressures that you are witnessing are well within operation norms and are nothing to be worried about. As long as you don't experience severe drops in oil pressure during acceleration and deceleration, then the oil pressure system is working well.

1999 suburban gage oil pressure is 0 when it warms up. rpm drop to 3-4 rpm when oil pressure goes to 0. Sounds good, runs excellent -no noise. Actually it sound better then most new cars. It is so...


I looked at info for 1500--5.7L engine.
6 psi @ 1000 rpms
18 psi@2000 rpms
24 psi @ 4000 rpms

Sometimes, you can use analog gage in place of oil pressure sending unit and double check oil pressure that way. If oil pressure is actually low, if high mileage engine, I doubt replacing oil pump will help. I just wanted to add, check oil pressure engine warmed up.

Oil pressure gauge reads 80 psi but computer reads 130 psi?


to be accurate on the reading i would use a oil psi guage and see the reading, and see what it says so you can compare the results.

2001 camaro 3800 eng. when eng is cold oil pressure is high after warms up oil pressure drop very low at idle. why??


When the engine and oil are cold it will show a high pressure because of the viscosity of the oil. When it warms up the oil is thinner. If it doesn't drop below 20-25 psi at warm idle I wouldn't worry about it as that is normal.

Oil pressure at 130 psi on display low down to 129 , where is the sending unit on 2002 buick lesabre?


should be on the housing near the oil filer on a v-6, behind passenger wheel at bottom of engine compartment. if not your local auto parts store should be able to look that up for you. if not any oil change shop can point it out to you.
