How to fix an oil pump leak on a 2004 ford mustang?

more info is needed on this, but I'll try to help you I will assume that this may be a 4.6 Romeo/ Windsor motor and if it is the oil pump is behind the timing cover and would not show a visible leak unless there is oil leaking from the cover gasket this would be the problem not the pump/next if you jack up the car put it on jack stands safely and look under it at the bottom of the engine there are a couple of things that could cause the leaking oil (1) oil filter loose/or to tight if there is oil all over it clean it off with a rag and let the motor run with the oil at the proper level if its loose or a broken O ring on the filter you will see the oil coming out if so change the filter and tighten till a good snug fit is achieved (2) the oil sender unit could be leaking oil from it this sender is screwed into the oil filter adapter and has an electrical plug on it the sealer on the threads may be leaking and can be fixed by cleaning and applying new sealer or the sender may be bad and needs to be replaced is the oil light coming on steady or on and off at times (3) if you clean everything off and then take baby powder and throw it all over these areas the leak will show up in the powder if you can't find it , if you see oil and antifreeze the green stuff leaking from the same spot behind the oil filter the adapter gasket is leaking be careful here because your cooling system can be clogged causing this gasket to leak go slowly and post back to me what you have done a step by step procedure will narrow this down to the cause I'm a taxi mechanic in N.Y.C. and 4.6's are what the crown Victoria's and Lincoln town cars have it's the same motor you must tell me if this is your motor if not I will still be able to help you further good luck in your search for the leak and do it safely a good jack and stands no junk stuff you'll be under the car and need assurance that you will be safe LATER MAN!

I have a 1999 Chrysler 300m with 156000 miles on it, i just replaced my oil pump due to the fact i thought it went bad, but little did i know after finishing it, It did not fix my problem. Well that is Car...

Could well be bearings and a lower oil pressure. Are there any codes, or just no power? If No power, then I suggest a rebuild of the engine. If codes, let's figure this out.

My 1995 cadillac northstar engine has locked up can it be fix by replacing the oil pump?

No, you cannot. If it has locked up due to no oil, then you are looking at a rebuild, and maybe even a total engine replacement because of the nature of the catastrophic failure.

No oil means the bearings had no lubrication, which chewed them up, as well as the crankshaft journals - Cam lobes, and maybe the connecting rod came apart and busted a hole in the block?

You could price a low mile motor from the same car at an auto recyclers - would be the best and cheapest way to go as long as you have a good mechanic that will thoroughly inspect the replacement motor before it is purchased and installed.

Good Luck.

Had the oil changed at walmart they put a fram filter on it and the filter caved now the motor appears to be locked up if the oil pump went out would it appear that the motor was locked up my husband...

Yes it is bearings, rings, and part of the cylinder. If the oil pump went out the motor would lock up. The oil pump pumps oil throughout the motor. If the pump quits, it is just like running the engine without any oil at all. Without oil pressure then the motor would lock up because nothing in the engine would get any lubrication. Don't think it has anything to do with the oil and filter. Probably just a faulty oil pump. I have heard of Walmart not putting oil back in cars, and causing them to lock up. But if you had oil in the car, and it has metal shavings, then it is more than likely the oil pump just quit.

Good day.Your problem may cause a second improper use of engine oil viscosity numbers, 2 low pressure in the lubricating system. In poor lubrication is needed to answer the question, a few deleted, and find out why these options: Suction basket is oil in order of entry is not blocked or distorted, and reduced oil flow?It is not clogged or restricted flow oil filter? Measure the device's real pressure oil pump provides oil and whether it is within the tolerances of the manufacturer? Determine whether or not clogged or otherwise restricted lubrication system in distribution channels of the engine? In the case where this all goes well then it will only be a faulty sensor lubricant pressure and still shows the "low pressure" in fact, it is good :-) The picture of oil system in your motor.fac423d.png

It sounds like an air lock or a fuel pump issue. firstly get the filter changed and bled through this might help. if the problem persists check the pump.

Jim, I think your oil pressure sender is going bad, you should replace it and see that your oil pressure is in fact good, you can also check and verify the wires to it at the same time. It is located next to the oil filter. Hope this helps, let me know

Fuel pump

Ok if the pump IS in fact operating it is possible that the pick-up has come off the pump or there is not enough fuel in the tank,
you do know that the fuel filter MUST BE CHANGED EVERY EVERY EVERY 15,000 miles forget changing the engine oil the fuel filtr is so much more important you can go 2-3 years without changing the engine oil just make sure its always full check it everytime you buy gas.
Well you need to do a fuel pressure test to confirm IF the fuel is the problem and you are not just assuming this. Too many times people assume fuel is their problem when in fact its the ignition system. Do a fuel pressure test it must be no less than specs and LISTED SPECS are the BARE MININUM THAT IT TAKES TO MAKE THE CAR RUN!email me with the findings at
