Before you spend money on a new gauge. Get an oil pressure testing gauge for $20 , remove the oil pressure sending unit and test the oil pressure. If oil pressure at idle and 3000 rpm's is a-ok via spec's ( big money repair items) then its either the gauge a clogged or defective sending unit or the circuitry. (little money repair items)
You can also have this done at a repair shop.

I have a nissan diesel 4 cylinder td27 engine , what i the normal oil pressure gauge reading for this engine whilst running


2.9 to 3.9 bar at 3000 rpm is fairly general for the Nissan range including turbo diesel, though the pressure isn't listed for the td27 engine. I doubt it would be more or less than the others.
I notice one Nissan commercial vehicle engine where 3.0 bar at 2000 rpm is specified.

The oil pressure test should be carried out at normal operating temperature.

Have you checked the PCV system?? If its stuck in the closed position then you will lack power and turbo boost. A vehicle needs 3 things to make it run proper; FUEL,FIRE and AIR. Try that and see if it helps.

Oil pressure is normal until it reaches200 degrees then oil presure drops to 10 pounds at an idle but give it gas and it goes up when its first started oil pressure is at 40 pounds until it reaches 200...


Oil pressure drop after reaching operating temp is normally caused by worn main bearings (depending on mileage).Worn bearings will allow pressure drop at idle and increase when accelerated above idle.

The Turbo Charger does not seem to engage .I was led to believe that after around 30 miles per hr. it would be like haveing a passing gear. Oh yes the car is a 1984 Nercedes SD 300 series Desiel.


The turbo charger has more to do with rpms than road speed.The turbo uses exhaust gas leaving the engine to push more fresh air into the engine thus creating higher compression and more horse power.You should feel some boost above 1500 rpms if everything is working properly.If not then you should have the system checked by a dealer or a good diesel shop.Good Luck!

The oil pressure on my 94 Trooper flucuates from around 10 at an idle up to 55-70 when I'm driving down the road. I changed the oil sending unit when I changed my oil thinking they both might help but I...


This seems pretty normal. So long as the pressure does not fall while driving, you're good.
When Idling there is very little stress on the engine, and it requires little oil pressure to maintain.
Additionally, the pressure is directly related to the rpm of the engine as the oil pump is driven by the engine. As the rpm increase, so does the pressure. The pressure should be stable at a given rpm.

The pressure on the high side is good. On the low side is adequate (idle). You did not say how many miles, but the only way to change this is to rebuild the engine with new bearings and seals. I don't think that's somthing you want to do. Sounds fine for now. Leave it alone.
Don't fall for a new oil pump. That is very rarely the issue.

The oil pressure gauge in my 2002 Duramax Diesel engine PU increases during acceleration and returns to normal following acceleration. Why would this happen?


That is normal. As you accelerate and rpm's increase the oil pump rpm increases. I think the oil pump runs 1 to 1 or 2 to 1 with the crankshaft rpm. Check the oil and inspect for any visual leaks if the gauge does not operate like that consistently. If it is intermittent or it just started acting that way, the sender my be bad. Other than that any Chevy Dealer will say that is normal.

Pressure of oil


You probably have a high mileage engine. Change the oil and go to a heavier oil viscosity and use a quality oil filter. This should help a little. If the engine has many miles on it this is about all you can do to boost the oil pressure. I don't know what engine you have. So you have one of two possibles here. A 302, a 351. A high mileage engine in either of these two engine configurations should have at least 20 pounds pressure at an idle and should rise as the engine rpm's increase. Good luck.

2002 duramax will heat up underload but not at idle any ideas why


No diesel I have ever owned will heat up to operating temp while idling. I have had semi's and dump truck and a Dodge with a Cummings turbo diesel. If you don't idle a diesel up to around 1200 rpm while sitting the combustion chamber temperature will drop because the diesel does not ignite fully at low rpm. You may also notice after an extended period of idling 1/2 hour or more that when you pull away the exhaust will be whitish blue because of the unburnt diesel fuel sitting on top of the rings. Also extended low idle will wash down the cylinder walls with unburnt diesel and remove the oil from lubricating the cylinders and rings. Hope this helps you understand why your diesel won't heat up while idling. Mike
