Low oil pressure - oil pump

1985 Ford Thunderbird 5.0(L)/302 - base model (not Elan or Fila). Can I replace the oil pump with the engine in vehicle? NOTE: Oil pan has front and rear sump. I have all tools needed to do repair. Also - what is the accepted oil pressure of this engine?

Thank you for your help.

    Thank you ccn7 - really appreciate the info - I thought I would have to
    pull the engine because of the dual sump. It's been a long time since I've had to do major engine work. Once again - thank you.

Well its been a while sense i have done one of thies, but i believe you have to unbolt both motor mounts and jack engine up as far as you can to get the pan off. if you can't get the pan off after you got engine jacked up as far as you can, you will have to unbolt front pump and take them both out at one time. and samething when you put it back together.if anything the picup tube is what will give you trouble, thats why you have to unbolt the pump.

    also i forgot to mention as long as you got the pan off it might be a good idea to pull 1 or 2 rod caps and main caps and take a look at them, they have ben known to wear down to the copper color if oil pump went out or very low oil pressure for awhile. also like i said its been a while sense i did one. if you run into a problem, give me a holler and i'll get back to you as quick as i can.

Need to know where the location of fuel pump is on 85 t -bird

If fuel injected- Central Fuel Injection, as I think it was, the electric pump should be in the gas tank. If still carbureted, it will have a mechanical fuel pump on the engine.

How to replace oil pump on 1985 ford 3/4 ton truck with small v8 motor

your can either pull the engine to do it, or if you can get or have enough clearnce to drain the oil and remove the oil pan you can do it with the engine still in ,i have done it both way's , eaither way the pan has to come down or off to get to the oil pump. if you don't have enough room when leaving the engine in you can take the motor mount bolts out and use a block of wood and gently jack the engine up to get the room you need to pull the pan down and to get in there and do the work.

How to put new oil pump in 4.6 thunderbird

You will need a service manual (Chilton's Haynes) for all of the correct torque specs and the correct disassembly/assembly sequences. That being said, the oil pump is a big job to change. You will need to disconnect the motor mounts and transmission mounts and raise the engine up so that the oil pan will clear the crossmember. If you can't get clearance doing that, the engine will need to come out. I would check the oil pressure with a mechanical guage to ensure that it indeed as low as it appears to be before beginning the endeavor.

1986 ford thunderbird oil gauge on and beeping

I would check that the engine oil level is high, then I would check that the pressure is high enough by plugging a gauge into the oil pressure switch socket after removing the oil pressure switch.

There is a possibility that the oil pressure switch is bad, or the oil pump has failed, unfortunately.

Low oil pressure where is oil pump

The oil pump is located inside the oil pan and is mounted to the engine block.
The removal of the oil pan is the only way to gain access to the oil pump.

The pump is driven by the end of the distibutor shaft which in turn is driven by the rotation of the cam shaft. There's a pickup tube that connects to the oil pump that goes to the lowest point of the oil pan, where the oil is drawn into the pump to lubircate the engine.
All of these are internal engine functions.

Hope this helps you with your question.

Location of oil pump on a 3.8 liter ford

It should be inside the oil pan. You will need to somehow get the oil
pan offf, in order to remove the oil pump. Make sure you check the
oil pressure to make sure that is the problem, before you go through
all that trouble getting to it?Good luck.

What does a low oil pressure alarm mean

It means the sensor that detects your oil pressure has seen a situation where the oil pressure is too low and engine damage will result. Could be just a bad sensor, but better have it checked with a mechanical gauge to see exactly what the pressure is.

Loosing oil pressure after car is warm, thicker oil is not helping

Your problem unfortunately is bearing related. When any oil is cold (regardless of rating) it is heavier than hot. Therefore, cold, with marginal engine crankshaft bearings, you have less bleed off around the bearing faces. Once warmed up, the oil is thinner and prone to more bleed off, lowering pressure. Once pressure is low enough you will begin to hear lifter noise, later, bearing knock. If in the early stages of failure, replacing engine bearings is an option provided that only rod bearings are worn (can be generally done in car. If mains are involved, engine needs to be removed. Oil pump should be replaced during this repair...changing oil pump without repairing the bearings will not fix the problem.

Low oil pressure

Probably 302 (5.0L) if not 3.8L v-6.
Anyway, fresh oil & new filter is a good place to start, then a little running down the highway may help loosen things up a bit. You can try adding a bottle of lucas, or similar, but personally I don't use that stuff. After sitting that long, oil will be pretty contaminated, so do that first, then I'd do it again after putting some miles on it.
