Oil leak on 1991 Dodge d150

Between oil pan and Transfer case (?). I only claim to be some what car savy. I have a 1991 Dodge D150 that is leaking oil between oil pan and transmission case. Initial thought was transmission leak, however, that is not issue. Degreased oil pan, no leak there or at drain plug either. Drained oil, still dripping oil. Again clean oil pan, clean transmission, leak is between the two at the botom of the truck. Also cleared valve gaskets, which may have been leaking some, but have been replaced. Please help.

You could possibly have a bad rear main crank seal.

have you smashed the sump ??never seen one leak yet?? sure its not the front or rear end oil seals ??..sounds like you have the sub frame in the way ,evan if you remove this bolt you will not be able to drop the sump without removing or lowering the sub frame assembly as the oil pick up pipe stops you from removing the sump in situe.Its not difficult to drop sub frame just time consuming

Sounds like the valve cover gasket, clean off all the oil on the engine with a pressure washer or a steam cleaner and then drive it and recheck for the leak, that way you can pin it down for sure.

SOURCE: Rear engine oil leak....

Oil leak can be attributed to several factors.
1. Gasket failure.
2. Uncontrolled Crank case pressure Failure.

RECOMENDATION:
Tighten both the valve cover and oil pan bolts.
Replace the Positive Crankcase Ventilation Valve and vacuum line.,

INFO: PCV
This is a valve causes a negative vacuum on the engine while its running, As to say if it had a leak in a valve cover it should not be leaking while its running, only when the engine it turned off.

Hope this tip guides you in the correct direction to solve this problem.

There is supposed to be a washer on the drain plug. It's either plastic or copper. It's either missing or more likely embedded with dirt or grit and won't seal properly. Simply pick up a new one when you do your next oil change and replace it then. Always wipe the oilpan off around the drain and clean the drain plug and washer before you re-install them. Hope this helps.

I have a 1991 d150 p/u and it has blue smoke from exhaust when started


If it smokes more when you first start it than other times, the common cause is leaking valve guides in the cyl heads.
The guides leak oil into the cylinders when the engine is not running.
Most other causes would make the engine smoke when running or under load too.

What kind of oil to use for a 1987 Dodge D150 Slant 6


You can use any oil you want. Just make sure that if you don't know what oil is in it currently that you drain the oil out and change the oil filter. Personally, I like the Chevron RPM oils and have two vehicles with over 200,000 miles that says they are good.

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.

How to put on a Oil Pump on a 89 dodge d150


if its a v8 its similar to the chevys. need to drop and steering linkage that is in the way of removing the oil pan. drain oil and drop pan. you will see a screen which is attached to the oil pump. the easiest way to remove this is a good flat head screwdriver and a rubber mallet or dead blow hammer. there is a lip on the screen that you can set the screw driver on. be very careful not to damage the screen unless you plan on replacing it. take note on where the screen is angled. this is important. you can measure with a steel rule or tape measure and measure from the screen to block or crank. remember measurement. its a tight fit so it may take some persuasion to get it out. once out remove th bolts holding the pump on. take your new pump and remove the cover plate that will expose the gears. hand pack the gears with a good assembly grease. then just reverse the steps. do not forget to angle the screen to the measurement you had.

My oil indicator light is on and i dont know what the probelm is?


It's usually an indication of low oil pressure. You can try changing the oil and adding a stability agent. The main bearings create and maintain the oil pressure so it's a good indication that they are getting worn.

1989 dodge d150 318


Did you have a hard start or no start problem recently ? If you did you were dumping fuel into engine with no spark, which ends up sitting on top of the piston & eventually running down into the oil pan. If not, my guess is you have an injector(s) leaking down while sitting. Check your PCV is clean & working as well.
