Low oil pressure engine noise

SOURCE: ticking noise and low oil pressure

DOES IT HAVE A LOT OF MILES ON IT OR MAY BE THE OIL PUMP IS IS GOING OUT? THERE IS A SPRING IN THE PUMP THAT IS A BYPASS FOR HOW HIGH PSI IT MAY HAVE BROKE THAT WILL GIVE YOU LOW PSI.

SOURCE: low oil pressure at idle

how low does the oil pressure drop?? is it below 40?

SOURCE: like 3 days after i got my oil changed in my 2006

This is an idication of a severe oil leak. Check the oil level in your engine to see if there is any in it. Add to the full mark and return to the oil change shop and ask them to see where the leak is. Do not operate without oil. Severe engine damage will occur. Hope this helps Moe

SOURCE: Engine has knocking noise. Oil is good. Started

Engine knock Huh? In order to qualify the term "Knock", Let me get you to perform some simple task/observation. Typically, if you hear a noise on top of your motor that can be described as a light knock, usually going tap, tap, tap, tapping along at double the tempo, of your motor spinning, Your oil pump may be having trouble getting oil to the top where the valve's and rocker arms are. If you hear a "Knock" by bending over or kneeling beside one of your "front wheel well's"and stick your head up to the well, providing a vantage point to "hear" whats going on at the lower part of the engine. A knock from here will/can indicate a potentially overheated, under lubricated, rod or crank bearing that could seize the motor. This (theretical) crank bearing would be sounding off at half the tempo of the rocker arms above., with a deep, dark klunk that would defintly present itself as the sort of noise that damages metal parts. Now, that being said.....common sense goes a long way, people....1.) Most people are aware of the maintenance that has been performed on a particular engine, the quality and quantity of that maint. and when the last time it was ran out of oil or water. For those who fall into the " lack of maintenence" catagory, you probably already know why your engine or driveline sound as it does. If you happen to take particulary good care of your car, there is a good chance that whatever noise or "happening" might be going on, it'll be much easier to remedy. There are always exceptions to every rule. Remember, its not what will happen, it's what can happen. Take care of your car, and it will take care of you. Theroad

If the check engine light is on, take the vehicle to an autoparts store and have them use a scan tool to retrieve any fault code(s) stored in the computer. Most parts stores offer this service at no charge. The fault code(s) will help narrow down the problem/potential problem. Sure hope this helps and best wishes.
