First, put a mechanical gauge on it and check the actual oil pressure.Should be no less than 15psi at idle, warmed up. (That is abslolute minimum, I like to see anything over 20) Unless the pickup screen is packed with debris, doing anything to the oil pump is a waste of time (pump gets oil before anything else in the engine and except for very rare times, is the last thing to fail in the system) Low pressure can be traced to worn bearings, 99% of the time! If this is the case, scrap the engine! If in fact little or no oil is getting to the heads, I'd flush engine and add a mild solvent/lubricant such as Marvel oil, then change the filter in approx 1000 miles, as it is possible that there is a sludge formation in a passage, but if completely blocked it would have destroyed the top end already! Hope this helps!!

Oil Gauge Dropping to 5 psi


Hi again Kelea, I'm glad to help!

Kelea, if you do not hear a lot of engine rattling noises then I would say your "Oil Pump" is OK and you need to replace the "OIL SENDING UNIT" which you can buy at Autozone. CAUTION: If you do hear a lot of rattling noises coming from your engine then I'd suggest having someone check the oil pressure. If the oil pressure is low then it could be all kinds of things that can cause low pressures. From engine bearings, to restrictions, to the oil pump itself. I would start with the oil sending unit first and see what your oil pressure looks like. If your oil pressure is good after replacing the sending unit then I'd consider never taking my vehicle back to the shop that told you it was the pump. Hope this helps and have awesome day.

Chrysler new yorker only low oil pressure


if you are full of oil, this could be as easy as an oil pressure sending unit, which you may see near the oil filter.

It could be an oil pump going bad, and you will be looking at a mechanic shop at that point.

I would check the connection of the oil pressure sending unit to make sure it's plugged in properly.

People have told me the pressure quit working after an oil change, and I found that in most cases, whoever changed the oil damaged that sensor.

The Oil light came on on my 1996 Mercury Sable I changed the Sending unit but that didn't help so I was told that it may be the oil pump I pulled the oil pan off, and removed the oil pump. I tore


Have you checked if the fault is your oil filter,probably the filter pressure valve inside doesn't keep any pressure? or the other thing is a possibility of the pressure pipes are clogged or semi clogged.

fuel pick-up in tank is blocked it has a sock over the end as a gross filter to keep out any big junk from getting sucked into the pump and causing damage to it. the sock can get so plugged up that no fuel will flow, causing the pump to run for a short time then with no fuel flow to cool it it trips the safety and shuts off

I have a 86 ford f-250 w/ a carbed 460.no fuel to carb. was told i had very low oil pressure.would changing oilpump and assending unit fix my propblem? do i have to pull motor to change oilpump? what...


If you're not getting fuel to the carburetor, check/change your fuel filter, check the fuel pump. And for the oil pressure you can change the oil pressure sending unit to see if thats the problem, for the oil pump the oil pan has to come off, it can be changed without pulling the engine, however you still have to lift the engine up.

Changed intake manifold gaskets, and while doing so, spilled a bit of coolant that was left in the intake in with the oil. Changed the oil before I even started my truck, and since then, I will have oil...


It sounds like oil pressure switch is bad. You said you changed? To clarify, your oil pressure switch is also a safety item that shuts down ignition when oil pressure drops. Try an oil pressure gauge (hand held) to relieve your nerves about engine seizure. Make sure you're not getting to much fuel in engine also, that will dilute oil to a thin viscosity and show low oil press.

The oil sending unit is located on the engine block behind the drivers cylinder head area.You have to climb up on the motor to see it cause it is hard to see behind the wiring harness.You may also want to purchase a new sending unit because it is very long and you might need to buy the sending unit socket to replace it.Hope this helps.Good luck.

I have a 2005 dodge magnum, an the iol light started comin on wen i am parked, wats causing that, i already had oil changed.


try replacing the oil sending unit first,
it tells the gauge on your dash how much pressure you have,if your light comes on it means you don't have oil pressure,so change the sending unit to see if this takes care of it,

93 chevy corsica. problem is after startup gas just pours out of the throttle body intake as the car stalls - probably half o cup of gas pours out. Is an injector stuck open? any advice?


Yes, most likely cause is an injector is stuck. The real problem is that you are removing the oil from the upper engine and it's protection with this issue.
Fix it forthwith, and when done, change the oil...it has been diluted by fuel...

2003 GMC Sierra Knock sensor and oil pressure??


the knock sensors are located below the intake plenum,or,upper intake manifold as some call it, they screw into the lower intake, the front one is sensor 1, the rear is sensor 2. it is wise to change both if you have some miles.since you are going to be buying a gasket set to do this job.the sensors are cheaper than the gaskets.
