SOURCE: Oil pressure for 2001 isuzu trooper

I'd check to see what is in the crankcase currently; with modern multirange oils, that sounds high.
The typical operating range is from 30-60#; 10 seems low for an idle pressure but then idiot lights are supposed to trigger at ~ 4# pressure.
If it was mine, I would change oil and put a multirange type suitable for your area in it to see what influence it has. If you are in a temperate climate as I am, it might be time to change from summer to a winter range; 10W30 is good for us and 10W40 in summer (WV).

Drop the small tin sump down and look at the longer of the pick up pipes for a bad O seal or cracking .
This lets the pump pull in air so you dont get pressure - some times they even fall right off .

SOURCE: low oil pressure

You didn't mention the actual pressure but an engine requires as low as 6 psi when the engine is idling and 15 to 20 psi while driving at higway speeds. Your Yukon requires a 5w-30 weight oil. If the oil used is correct, you will want to have the pressure sending unit and gauge checked.
A mechanic will install a "mechanical" oil pressure gauge tester on the engine to find out what the actual oil pressure is. If the mechanical tester says the oil pressure is good, he will then begin to diagnose the electrical pressure gauge system.
If on the other hand, the mechanical gauge verifies the pressure is still low, he must diagnose the engine mechanical problem that is causing the low pressure issue.
Good luck.

SOURCE: low oil pressure 93 GMC P/U w/350 motor w/205,000 miles gauge

While engine is running, open the cover where you add oil to engine and see if you see a good flow of oil, if good flow, could be as easy as replacing oil sending sensor. got to realize that if poor maintenance history your engine may not be building enough pressure at iddle to move your hydraulic operated valves, only when you rev it up it will pump enough to run smooth. if running engine too long, you may cause more damage to other engine components such as crankshaft and cam shaft bearings. if you can spare a few bucks, have a good mechanic check your oil pressure with a mechanical gauge. another cheap option is to replace oil pump. last resort if you love your truck as much as we do,replace engine or rebuild it. At 205,000 this is a normal symptom, other than timing chain problems, most engines don't make it that far. hope this helps!

Oil pressure problem


if you have a 4jx1 3.0 engine then the engine wont run properly because engine oil pressure is what drives the direct injection system.
Check for blocked oil filters 2 pieces if not remove the oil pan and check the oil pickup tube for oil sludge blockage

Oil pressure problem


in a shop we ignore the dash gauges and use REAL gauges.
we attach a real gauge to the sender port. on engine block.
and read the true pressure.
the lamp on most cars go on at 3 to 5psi.
this is catastrophic failure. that low.

my guess, is you let oil drop and you wrecked bearings.
but let the real gauge prove that , dont guess.

Whats oil pressure on 3.1 isuzu


4psi idle (bad) and revving to 3k does what, you didnt say.
what was idle RPM 800 or 400>?
the answer is different by hot and cold oil
and oil type, no type stated (do not say brands) 10w30?
running 0w are you>?
and is as low as 8psi hot. at idle ,that is if idle speed is at spec.
is it?
and 3000 rpm would be like 25psi hot, and more cold.
the max pressure will be the pump regulator value.

here is the sensor spec.

The sensor closes when the oil pressure drops to between 4-7 psi (28-48 kPa).

the oil type and bearings clearances (in total) dictate pressure.

3,1 CPC engine spec is.

OIL CONSUMPTION 2002 4X4 TROOPER.


have an accredited service shop to a wet and dry compression test on the engine
That determines engine condition
have the oil pressure checked using a mechanical gauge and if the pressure is below specs that indicates worn bearings overloading the oil control rings
leaks can be rear main seal or crank shaft seal at the front where the oil is blown away in the slip stream

Why does my oil pressure gauge on dash show low oil pressure when slowing . or during long drives when using low revs


The reason would be physics based. Low pressure can go down to under 10 psi. and be okay. What you do is hook up an external gauge and measure your pressure, both cold and warmed up. Your pressure may be okay.

ISUZU TROOPER 3L injectors, what oil pressure do they require to make them work


at cranking the oil pressure has to be approx 5 mPa before they start to work electrically also, oil pressure at rail varies from 4 to 28 mPa. on Tech2 scanner in data list rail oil pressure should be close to desired and when engine not running sensor should read 0 - 0.2 mPa if higher or a negative value when engine not running this indicates problem with rail oil pressure sensor which is a common problem.

Drop the tin sump and check the pick up pipe as the pipe can crack and the seal goes hard so lets some air air in for a bit .

2001 Trooper turbodiesel oil pressure gauge


check oil pressure with test gauge from near large engine oil filter and cooler assembly, to rule out sender unit issue, if same readings check oil pick up sucking air O ring leaking?
releif valves in oil filter cooler assembly, stuck/jamming open?
if vehicle has been sitting for a couple of days and this happens light should only stay on 1-2 seconds go out and then gauge starts reading
have seen this on older higher km vehicles bad ones have balance shaft centre journal in sump worn out (new sump)
