Put a manual oil pressue gauge on the truck and make sure your not losing oil pressure, it would not be wise to assume the gauge is bad and turns out your wrong and need a new motor ;(. could be the sending unit but best to check for pressure before throwing any parts at it please rate -jeff

1995 dodge V10 185000 miles. When you start it you don't have oil pressure and at an idle it won't go up. rev the engine 15 to 20 sec. oil pressure go up to 40 lbs. and stays there even at idle.


I would install a test mechanical gage on the engine (remove sender and install there) and see if the oil pressure really is low when it is started.

Dodge v10 loss oil pressure ownly win idleing


Old engine tend to wear piston ring in time,if you use wrong viscosity grade oil ,during idling the oil could not reach all moving parts because there is no enough oil pressure in the system,try 30/ 40 oil grade .

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.

I have a 2000 Mercury Cougar and the gauge inside tells me that the engine is over heating, no heat is coming from the heater when I turn it on, the fan for the engine is running at full blast, the engine...


Hi,

The overheating and lack of cabin heat both point to a failed engine thermostat which would be stuck closed. At the warm up stage, the coolant stays in the engine block to bring the engine to efficient operating temperature, then it opens and circulates the coolant through the radiator and heat core. If the thermostat is stuck closed, the engine will overheat, and coolant will never reach the heater core, and you will not get cabin heat.

Blinking oil light at idle which goes away during driving could be a low oil level, but may also be a drop in oil pressue. You could have a clogged oil fliter (at best) pickup tube, or a failing oil pump.

Oil pressure gage drops to 40 at idle


40 pounds of pressure at idle is fine, no worries with that.

Oil pressure reading in 2003 gmc envoy


No problem with the oil pressure, the norm is between 40 to 60. Anything lower then 40 you have low oil pressure and anything above 60 then you have high oil pressure which is caused by a blockage in the system.
What is common is the oil pressure gage fluctuating for the first 200 miles if the oil pressure sending unit is getting worn. Good maintenance will keep the engine clean and running good but the oil pressure sending unit is inexpensive and easy to replace. Next time you do an oil change you can have them change the sending unit.
Good luck and hope this helps. You can pick up the sending unit at Auto Zone and most auto parts store and will have the step by step to replacing it. If you do attempt to replace it. make sure you DO NOT USE any Teflon tape or silicon on the threads, they are tapered and need a good ground to the engine for proper readings.

Low oil pressure


the first i would do is to see if the oil sending unit is ok and if you gage is working right and if they are then checkout the oil pump.

Engine running hot


Check the condition of the coolant.
If you have any indication of oil, the headgasket could be bad.
