Where is oil leaking from just above oil pan and around timing belt cover?

I'm sorry, but I can't provide visual images or diagrams. However, I can describe the general order of gaskets in a 1999 Dodge Durango engine from the top going down:

1. Valve Cover Gaskets: These gaskets are located on top of the cylinder heads and seal the valve covers. They help prevent oil leaks from the top of the engine.
2. Intake Manifold Gasket: The intake manifold gasket seals the connection between the intake manifold and the cylinder heads. It helps maintain proper air-fuel mixture and prevents vacuum leaks.
3. Throttle Body Gasket: If equipped, the throttle body gasket seals the connection between the throttle body and the intake manifold. It ensures proper airflow into the engine.
4. Exhaust Manifold Gaskets: These gaskets are located between the exhaust manifold and the cylinder heads. They seal the exhaust gases and prevent leaks.
5. Head Gaskets: The head gaskets are situated between the cylinder heads and the engine block. They seal the combustion chambers and coolant passages.
6. Oil Pan Gasket: The oil pan gasket is located at the bottom of the engine and seals the oil pan to the engine block. It prevents oil leaks from the oil pan.
7. Front and Rear Main Seals: These seals are located at the front and rear of the engine crankshaft. They prevent oil leaks where the crankshaft exits the engine block.
8. Timing Cover Gasket: If equipped, the timing cover gasket seals the timing chain or belt cover to the engine block. It helps protect the timing components and prevents oil leaks.

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 theintake 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, theoil 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.

I think it helps to analyse u r Problem

1. timing cover is leaking oil betwwen cover and block
   
2. Disconnect the negative battery cable.
   
3. Remove the drive belt(s), fan and fan shroud. If equipped, remove the accessory drive belt pulley.
   
4. Remove the vibration damper retaining bolt and washer. Remove the vibration damper using a suitable puller.
   
5. Remove the accessory drive brackets attached to the timing cover.
   
6. Remove the A/C compressor, if equipped, and alternator bracket from the cylinder head and move to one side.
   
7. Remove the oil pan-to-timing case cover bolts and the cover-to-cylinder block bolts.
   
8. Remove the timing case cover front seal and gasket from the engine.
   
9. Cut off the oil pan side gasket end tabs and oil pan front seal tabs flush with the front face of the cylinder block. Remove the gasket tabs.
   
10. Clean the timing case cover, oil pan and cylinder block gasket surfaces.
    
11. Remove the crankshaft seal oil seal from the cover by prying it out with a suitable tool.
    

To install:

1. Install a new seal in the timing cover using a suitable seal installation tool.
   
2. Apply sealer to both sides of the replacement cover gasket and position the gasket on the cylinder block. Cut the end tabs off the replacement oil pan gasket corresponding to those cut off the original gasket. Attach the end tabs to the oil pan with sealer.
   
3. Coat the front cover seal end tab recesses generously with sealer and position the seal on the timing cover.
   
4. Apply engine oil to the seal-oil pan contact surface, then position the cover on the cylinder block.
   
5. Insert timing case cover alignment tool J22248 or equivalent, in the crankshaft opening. Install the cover-to-cylinder block bolts and tighten them to 62 inch lbs. (7 Nm). Install and tighten the oil pan-to-cover bolts to 11 ft. lbs. (13 Nm).
   
6. Remove the cover alignment tool and position a replacement oil seal on the tool with the seal lip facing outward. Apply a light coat of sealer to the seal and a light coat of oil to the crankshaft. Install the seal on the timing cover.
   
7. Apply a light film of oil to the vibration damper hub seal contact surface. Install the vibration damper using a suitable installation tool.
   

Do not hammer the damper into place as damage may result to the damper or engine.

1. Install and tighten the crankshaft vibration damper bolt to 80 ft. lbs. (108 Nm).
   
2. If equipped, install the crankshaft pulley and tighten the bolts to 20 ft. lbs. (27 Nm).
   
3. Install the accessory brackets.
   
4. Install the fan and fan shroud.
   
5. Install the drive belt(s) and adjust to the proper tension.
   
6. Connect the negative battery cable.
   
7. Start the engine and check for leaks

yes, I just changed one of these recently. Had to take both front and bottom off engine. Very difficult repair, as there are no good jack points for the engine when you have all the motor mounts off.
Here is procedure I would recommend.
Remove starter and engine to transmission brackets front and back.
Remove transmission starter gear cover.
drain oil and remove oil pan.
put a block under the crankshaft and jack to release weight on motor mount.
remove front motor mount (by serpentine belt)
remove belt.
remove compressor and bracket.
remove crank pulley and vib damper.
remove timing cover. mark timing belt with direction of travel
loosen tensioner gear.
remove timing belt.
remove crankshaft timing gear and key.
remove seal and oil pump housing.
clean gasket surfaces.
replace seal and reverse procedure.

If you have questions, let me know.

OIL LEAKS UNDER CAR COULD BE COMING FROM LEAKING OIL FILTER OR OIL PAN GASKET.CHECK FOR OIL LEAKS AROUND REAR MAIN OIL SEAL AND FRONT TIMING COVER CRANKSHAFT SEAL LEAKING OR LIP SEAL AT THE LOWER TIMING COVER TO OIL PAN.

check front crank seal ive replaced lots of those and you may have to sleeve the crank pully

there are seals behind the timing cover.when they leak oil drips down and out.my 93 base model leaks oil and coolant from this same place.

On a 22RE the oil pump is on the timing cover behind the crank pulley/harmonic balancer,it has the crank timing pointer built onto it,generally they don't leak around the pump seal but as Monster80 pointed out they leak from the front main seal wich is installed on the front of the oil pump,pretty common for the 22R/RE to leak around the timing cover gaskets or out the bolt holes on the timing cover also,usually due to uneven tourqe on the bolts,to check the front main seal you need to look at the the crank from the underside right after you've shut the motor down,if the seals bad you'll see oil starting to form a drop on the backside of the pulley or the front of the oil pump housing.

Could be a rear main seal.
