Palio 1.2. Why is there no oil pressure?


Very low or no oil pressure reading does not necessarily mean the oil pump is not working and if you replaced the oil pump because of low oil pressure does not mean the original pump had necessarily failed. It may have but it may not have. Oil pressure is not created by the oil pump but by the resistance to oil flow. If you have very low resistance to flow you will get very low oil pressure no matter how well the oil pump is pumping. If you have a very worn engine, especially the bottom end main bearings and conrod bearings, tolerances increase very significantly, there is little resistance to flow and you will achieve very low oil pressure and metal parts will touch. Oil flow to the upper part of the engine may also suffer. If your engine is gummed up with oil sludge due to too few oil changes some oil passages may be blocked as well.

I have a 1992 dodge D150 with a 5.2L and oil pump is going bad, how do I remove and replace it?? Thks John


5.2L and 5.9L Engines
It is necessary to remove the oil pan, and to remove the oil pump from the rear main bearing cap to service the oil pump.
  1. Drain the engine oil and remove the oil pan.
  2. Remove the oil pump mounting bolts and remove the oil pump from the rear main bearing cap.

To install:
  1. Install the pump and tighten the cover bolts to 95 inch lbs. (11 Nm).
  2. Prime the oil pump before installation by filling the rotor cavity with engine oil. Install the oil pump on the engine and tighten attaching bolts to 30 ft. lbs. (41 Nm).
  3. Install the oil pan.
  4. Fill the engine with the proper grade motor oil. Start the engine and check for leaks.

Can you remove the oil pan to change the oil pump without lifting the engine off the motor mounts? Also, if the pump is not bad, what gear drives the pump in the upper part of the engine and could it be...


No. You have to lift the engine. The distributor has a gear on it. this is what drives the oil pump. Most times 99% the bearings are worn out causing low oil pressure. I have replaced oil pumps, not because they were bad, but because someone wanted a high pressure pump. The first thing I would do if I suspected oil pressure problems is put a mechanical guage on the engine. If the oil pressure is normal then all you need to do is replace the oil sending unit. Of course if you knocking in the lower engine, then it would be bad bearings. Forget the pump. you need to replace the engine

302 ci. 5.0 ltr . oil pump replacement


Why do you want to replace the oil pump? I am asking this question for good reason. Engines that have worn bearings will have low oil pressure, and replacing the pump will not solve this problem. If you are replacing the pump because of low pressure, then you really need to consider correcting the cause of the low pressure. To replace the pump, you need to remove the oil pan from the bottom of the engine, which will likely involve raising the engine. Once the oil pan is off, you can readily remove and replace the oil pump.

How to replace oil pump


REMOVAL & INSTALLATION

Gasoline Engines
See Figures 1 and 2

Fig. Fig. 1: Exploded view of the oil pump used on 2.0L and 2.3L gasoline engines


20995b0.jpg
Fig. Fig. 2: Exploded view of the oil pump used on the 4.0L engine-2.8L and 2.9L engines are similar
  1. Follow the service procedures under Oil Pan Removal and remove the oil pan assembly.
  2. Remove the oil pump retainer bolts and remove the oil pump.

To install:
  1. Prime the oil pump with clean engine oil by filling either the inlet or outlet port with clean engine oil.
  2. Rotate the pump shaft to distribute the oil within the pump body. Install the pump and tighten the mounting bolts to 14-21 ft. lbs. on 2.0L and 2.3L engines; 6-10 ft. lbs. on 2.8L and 2.9L engines or 13-15 ft. lbs. on 4.0L engines.

Do not force the oil pump if it does not seat readily. The oil pump driveshaft may be misaligned with the distributor shaft assembly. To align, rotate the intermediate driveshaft into a new position.
  1. Install the oil pan as previously described. The oil pumps are not serviceable. If defective, they must be replaced.

Remember rated this.

92 voyager oil pump replacement.


Remove the engine front cover then drain the engine oil and take out the oil pan. It is under the engine and looks like the bottom of the motor.
Unscrew the oil pump mounting bolts with a wrench and proceed to remove the oil pump itself by pulling it down and out of the engine. Avoid getting any contaminants into the oil pump assembly while removing.
Add fresh oil to the new pump to prime it. Check the alignment on the new oil pump drive with the crankshaft/intermediate crankshaft timing.
  • Step 2 Install the new pump carefully, rotating it back and forth a little to make sure it has full surface contact between the pump and the engine block.
  • Step 3 Hold the pump in its sealed position and put in the pump mounting bolts, tightening them to 15 ft-lb.
  • Step 4 Put the engine oil pan back in and refill the crankcase. Start the engine and check for leaks on the parts you replaced
