Rear main seal....
Look above the pan, it may be drooling down from above like at valve cover gaskets or oil filter....

Testimonial: "Is it expensive to fix ?"

  • mark thompson Dec 16, 2014

    Could be cost prohibitive depending on how much the purchase price is. If the purchase price is inexpensive enough, may be worth it. Factor in mileage and be sure to have the frame inspected on this vehicle BEFORE you negotiate price; they are KNOWN for frame problems just behind the doors and at the leaf spring hangers.

SOURCE: 2002 Jeep Wrangler appears the

It is the oil pan gasket all you have to do is drop the oil pan clean the bottom of the engine block and the surface of the oil pan and install the oil pan again. a very simple process. Make sure that it is not the rear main crank seal that is leaking. If it is the rear main then you will have to remove the tranny to replace the rear main seal.

SOURCE: Jeep Wrangler leaking coolant

IT IS THE WATER-PUMP. PLEASE DON'T WAIT FOR IT TO OVER-HEAT BECAUSE THEN IT WILL BE TOO LATE, AND VERY COSTLY. PRICE A HEAD-GASKET JOB AND COMPARE IT TO THE COST OF A WATER PUMP. HOPE THIS HELPS YOU MAKE THE RIGHT CHOICE. BEST OF LUCK.

SOURCE: Oil pan removal on a 97 jeep wrangler

Instructions can be found in any basic manual but the simple version is to remove anything obvious that will be in your way (starter, trans lines etc). Disconnect both engine mounts and raise engine to get better clearance (watch stuff on top so you don't break anything) I usually stuff a couple of 2x4 wood blocks between engine & mounts to support it. Remove all pan bolts and take it down (remember pump pickup will interfere) Do what you need to do, then reverse process.

SOURCE: oil leak at the bottom of the oil pan.

Dear Sir,
Here is the oil leaking Problem Identifying Technique

Engine oil leaks from the valve cover gasket are common.

  • The intake manifold plenum gasket may leak and cause increased oil consumption/burning and a spark knock during acceleration; the gasket should be replaced.
  • External oil leaks from valve cover gaskets, intake gaskets (front or rear), and the rear crankshaft (rear main) seal area are common. The rear main seal is an unlikely source. Normally, the bearing cap mating surfaces (as well as the sealing surface between the oil pan and bearing cap) are the source for the leaks.
  • Engine oil leaks at the distributor can be misdiagnosed as leaks from the intake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.
  • If the oil filter casing shows signs of distortion from excessive oil pressure, the oil pump should be replaced.
  • Often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.
  • Carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.

    the oil seal shield is fitted to the yoke on the tail shaft. I had a similar noise it was a cord caught around the tail shaft an hitting on the body.

    Transmission and oil leaking in to oil pan under a 1999 jeep no seeable leak points but its a class 2 leak ( drips forming but no puddle under the vehicle)

    There are three places above that pan that the leaks could be coming from. 1- Tail shaft of the transmission.Would be a red color. 2-3- Input and Output shafts on the transfer case. More the color of motor oil. There may be more oil in that skid pan just not at the correct angel to let it run off.

    I recently bought my 17 yr old daughter a 1997 Wrangler sport. After a few days I noticed a small oil leak under the vehicle. I brought it to my mechanic who had to replace the rear oil seal. A few days...

    Mate.If its a six cyl, motor the rear seal wasn't done right.Its a 2 part seal and you have to remove the sump to do it. The mechanic doesn't want to admit a stuffup.The most common cause is not the correct sealer when the new seal is installed.It has to be slid around and in with the bearing cap removed.This is on a 6 cyl.Hope this helps

    1998 Jeep Wrangler Sport tail lights don't work. Stop lamps, turn signals, reverse lamps all work. Everything seems to work except the tail lights.

    if the bulbs are good, the only thing left is the headlight switch, or wires. black/yellow wires from the switch all the way back to bulbs. ck power to the bulbs first. if no power, then ck power at switch.

    1995 jeep yj 5 speed AX-5

    Where are you seeing the oil leaking from? Remember that gravity will cause the oil to drop down. The wind will also cause the oil to blow back while you drive. Look for the forward most and top most areas that are covered with oil. Common leak areas are the front oil seal (oil will look like it's coming from the bell-housing. Another common leak is the shifter plate gasket, just below the shift lever. Oil will be found draining from this area. I have also seen shoddy mechanics use the wrong bolts to hold the rear housing onto the main housing of the transmission. If the bolts used are to short, oil will leak between the main housing and the tail-shaft housing. Charlie

    Will a 1998 jeep 4L 2.5 motor work in a 1991 jeep wrangler?

    Most likely yes. One thing about the older Jeeps is that they did not change the models much from year to year. If the two jeeps had the same engine, they are probably nearly 100% interchangeable.

    My heater fan will not work in any speed on my 98 cddy deville

    your blower motor is under the hood. If you can't buy one try drilling a hole in the back of motor where the bearing is use a real small drill bit. Then you can oil the back bearing .You have to take the blower out to oil the front.The only way to do it is squirt it on the shaft and just let it run down.
