Question about 2002 Isuzu Rodeo

1 Answer

Oil pressure drops to zero after warmed up or below 2700 RPM

My oil pressure is within allowable limits when my 1996 Isuzu Rodeo 3.2 liter is first started. After the vehicle is warmed to standard operating temperature, oil pressure drops to zero when engine RPM’s are below 2700. The oil pressure will go back up to 60 psi when engine RPM is above 2700 RPM. The engine still sounds smooth and strong. This engine does not click, knock, or ping. Engine has always carried sufficient oil and never too much. The vehicle and engine have 130,000 miles. Timing belt was changed at 120,000.

Check the oil pressure with a test guage, if the finding are the same, the look at your oil filter, pump, pickup, or pressure relief valve.....

SOURCE: pinging sound from vehicle

The pinging is commonly caused by fuel problems ... usually a tankful or two of premium will clear it up. If not have it checked.

The front and rear shocks are different. You can even check this by going to www.autozone.com

CAN A OIL PRESSURE GO DOWN TO 25 WHILE IN GEAR AND 40 WHILE HITING THE GAS IT SHOLD STAY AT 40 45 NORMALY NO MATER WHAT RIGHT ITS A 2000 DENALI 4X4 I DO HAVE ISSUES WITH 02 SENSORS IS THAT THE REASON WHY


Oil pressure is not constant, while idiling the pressure is less than when accelerating. Usually when the oil pressure gauge fluctuates it is a sign of low oil level.

Alrighty. I've asked this a few times before, I have more info now. CHEVY 350 K1500. 1993. Replaced intake gaskets, (bad oil leak) dropped a small amount of coolant in with oil while doing so. Changed oil...


how did you clean the gasket off of the head? if you used a sanding disc the grit will eat up the bearings. are you reading pressure with a mechanical gauge? you have replaced all bearings??

6 psi @ 1000 RPM
18 psi @ 2000 RPM
24 psi @ 4000 RPM
this is chevrolet specs on oil pressure in your truck so you are within the range.

describe your idle problem more and i will try and help you with that

Oil gage goes to zero when i stop but goes up when i take off also using lots of oil but no smoke out the exhaust does this mean my oil pump is going bad 1996 isuzu rodeo


May mean yor engine is burning the oil or you have a leak.
Look in coolant recovery tank or radiator when vehicle is cold and is if coolant is milky or there is oil in it.If either of these conditions are there you may have a bad head gasket.
If none of these conditions are there then have the vehicle inspected for oil leaks.
Arears to focus on: Rear main seal,oil pan,valve cover gaskets, cam and crank shaft seals, oil pump seal and gasket.
Good luck

I have an Isuzu Rodeo 3.2 L when the engine is cold, motor sound good oil pressure is between 30 and 55 as it starts to get hotter oil pressure drops and the rocker arms start to rattle. When engine is...


The oil pressure in an engine will naturally drop off as the engine warms up. If the oil pressure is dropping too much it could be cause by several things. I don't know how many miles your engine has on it but the oil pump may be getting weak and may need to be replaced. Worn out cam bearings or crank bearings can also cause low oil pressure. Sounds like your engine may be ready for a rebuild

My oil pressure gauge is fine when the car is started then after running for a while the gauge jumps and gets close and sometimes goes to zero could that be the pressure switch? So far it has not shut off...


sounds like possible oil starvation due to leak in pick up or supply galleries
suggest checking with proper test gauge to see if its the same
if it is the same check pressure relief valve in pump (to see if jamming open)
then check pick up in sump and "O" ring

Oil used in a 1992 Isuzu Rodeo


depends on your temperature, and where you live if it uses a little oil use a little heavier to cut consumption. If it is always cold where you live like below zero, I wouldn't use more than a 20w 30w. in warm climates a 30 weight oil is ok, but if you have low oil pressure you can safely use forty weight.
