Why is my oil pressure so low in my car?
Oil pressure gauge reading too low, generally below 15 to 20 PSI while idling. Cold weather can also make the oil pressure read low until the oil pump has had a chance to deliver the oil to the engine.
What are the problems with an oil pump?
Problems with the Oil Pump: Any sort of air leakage in the supply side of the oil pump will also cause cavitation (back pressure) and loss of oil pressure. The engine builder should check the supply side of the oil pump and make any necessary repairs. The other common issue with the oil pump is excess wear to the gears.
Why does my blood pressure drop when I stop the oil pump?
While the oil pump is not a human heart, its function is quite similar to that. Hence, when it gets damaged, you can expect the pressure within the oil passages of the engine to drop, too. Stop the heart and you also lose blood pressure or you have a drop in blood pressure. There are many causes of oil pump failure.
What are the symptoms of low oil pressure?

What’s the oil pump pressure on a Pontiac?
He continues: “The M-54D oil pump is designed as a replacement for any 265-455ci Pontiac engine and uses the larger ¾-inch-diameter inlet opening. Its pressure bypass is set at 50 psi.
Why does my oil pump have low pressure?
(Engine oil pan removed while turned over.) Step 5 – The oil pump is also designed with an oil pressure relief valve and spring which regulates pressure. If this valve becomes faulty caused by a broken pressure spring the pump will have low oil pressure.
Why does my car have no oil pressure?
When these bearings wear, they can allow more oil to escape causing low oil pressure, this is a sign the engine has worn out and replacement or rebuilding is needed. Step 7 – If the engine has no oil pressure, suspect the oil pump drive, some manufactures use a belt to drive the pump which are prone to failure.
What should the pressure be on a Pontiac V-8?
When dealing with a typical Pontiac V-8 and production-bearing clearances, pressure at the gauge is usually 60 and 80 psi, respectively. Melling’s Select Performance oil pumps were first introduced in the early ’90s and incorporate improvements to the pump design, displacement, tolerances, materials, and coatings.
