What should the pressure be on the oil pump?
What should the pressure be on the oil pump?
A relief valve close to the oil pump opens when the pressure reaches a predetermined value, usually between 45 and 75 psi, allowing extra oil to drain back into the oil pan. However, when the lubrication system can’t maintain proper oil flow, or pressure drops when it should not, engine components are going to be starved of much-needed oil.
What happens when oil pressure is too high?
The faster the engine moves, the higher the rate of oil flow and the higher the pressure. Too much pressure can be damaging to engine components, though. A relief valve close to the oil pump opens when the pressure reaches a predetermined value, usually between 45 and 75 psi, allowing extra oil to drain back into the oil pan.
What to do if oil pressure drops after changing oil sending unit?

What to do if your oil pressure is too low?
Some vehicle models come equipped with a low-oil-pressure safety circuit. The circuit connects to the car computer, and the computer disables the ignition system when too much oil pressure is lost. This is to prevent the engine from serious mechanical damage.
Why does the oil needle bounce on a dumptruck?
The actual pressure wouldn’t be wildly fluctuating like that. Click to expand… Those were my exact words about a 1997 Ford 460 in a dumptruck. Then the engine had to be replaced. Learned my lesson! Get a mechanical oil pressure gauge on there immediately.
Why does the oil gauge needle bounce so fast?
The needle actually bounces like I’m hitting bumps, super fast, kinda like a really fast vibration. I’ll take a video with my phone. There’s no way oil pressure could vary that fast, it’s too thick to react like that, but taking no chances. AllOffTopic.com FTW! The one in that Ford went its complete range so fast sometimes that it was a blur.

Why does the oil needle bounce in a GMC Truck?
The one in that Ford went its complete range so fast sometimes that it was a blur. Its movement made a buzzing noise rather than individual ticks as it reached its extremities. I was sure oil could not work that way. I think what happened was the oil was foamed up or full of bubbles or something.
