I have colant leaking from between the timing chain cover and the engin ca i get a digram to show how to replace the gasket?

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.

Oil leakage in the timing compartment of an engine can be caused by a variety of factors. Some common causes include:

1. Worn or damaged valve cover gasket: The valve cover gasket is responsible for preventing oil from leaking out of the timing compartment. If this gasket becomes worn or damaged, oil can leak out of the compartment.
2. Worn or damaged timing chain cover gasket: The timing chain cover gasket is responsible for preventing oil from leaking out of the timing compartment. If this gasket becomes worn or damaged, oil can leak out of the compartment.
3. Worn or damaged oil pan gasket: The oil pan gasket is responsible for preventing oil from leaking out of the timing compartment. If this gasket becomes worn or damaged, oil can leak out of the compartment.
4. Worn or damaged crankshaft seal: The crankshaft seal is responsible for preventing oil from leaking out of the timing compartment. If this seal becomes worn or damaged, oil can leak out of the compartment.
5. Worn or damaged camshaft seal: The camshaft seal is responsible for preventing oil from leaking out of the timing compartment. If this seal becomes worn or damaged, oil can leak out of the compartment.
6. Worn or damaged Timing chain tensioner: Timing chain tensioner is responsible for maintaining proper tension on the timing chain. If this tensioner becomes worn or damaged, oil can leak out of the compartment.
7. Worn or damaged Timing Chain: Timing chain is responsible for maintaining proper timing of the engine. If the timing chain becomes worn or damaged, it can cause oil leakage in the timing compartment.
8. Low oil level: If the oil level in the engine is low, it can cause oil to leak out of the timing compartment.

It's important to address oil leaks as soon as possible, as they can lead to serious engine damage if left unchecked. To determine the exact cause of oil leakage, it's best to consult with a mechanic or take the car to the service center.

Is this for a gasket or for the timing chain replacement ?
It's pretty complicated engine but that seems high for just a gasket.
It may be that you were quoted for a timing chain replacement along with the gasket repair.
Ask for clarification and get a second estimate.
If it's not leaking that much and little oil spots/droplets aren't showing up on the rear of the vehicle and you check the oil all the time, $3900 will buy a lot of oil.

Yes the timing cover gasket can leak coolant. The coolant passes the waterpump and is pump into the engine block thru the timing cover. to see the actual leak jack up passenger side of car support with jack stand take off wheel and the splash guard now you can see the crank shaft pulley look up at waterpump on both side it goes back to engine block with a mirror you can see it leak.

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

Common problem. You are in for a rough ride my friend. The only way to fix that is to remove the rest of the bolts, the front crankshaft dampener pulley and take the timing chain cover off. Usually the bolt is seized into the timing cover itself and the timing cover ends up getting destroyed in the process. Once the cover is out of the way, the bolt will most likely come out fairly easilly with a pair of Vise-Grips.

Fortunately, a replacement timing chain cover is not real expensive. The trick is to get the [BLANKETY] thing off without causing any damage to the engine block. If you are going that far, I recommend putting a new timing chain set on it while you are in there.

Recommended parts: Timing cover gasket and front seal set, timing chain and gear set, and possibly a new timing cover unless you can get it off without ANY damage.

Keep in mind that if you have to pry it off and the pry tool leaves indentations in the gasket surface, or if you "warp" the cover, the timing cover MUST be replaced unless you want to do the job over to fix oil and engine coolant leaks. (It doesn't take much to make the thing leak)

CHECK FOR LEAKING WATER PUMP WEEP HOLE OR GASKET.ALSO CHECK WATER PUMP HOSE FOR LEAKS.IF ALL LOOKS GOOD.YOU COULD HAVE PINHOLE LEAKS IN RADIATOR CORE LEAKING ON FRONT OF ENGINE OR INTAKE MANIFOLD GASKET LEAKING COOLANT.

check the timing chain tensioner gasket assembly and replace those gaskets and the rocker cover gasket you took off to do the chain work

sounds like the engin took a real wack????
i hope you eat that deer!! its cost you dear to fix it?
you could do the gasket in place but its a right old job,,,when mine started leaking i just tiped in a big bottle of rad weld or block weld (stop leak) what ever you call it,,, it stoped the leak dead in its tracks for years (3 or 4 years) till i sold the truck??
as for bad running yes it could be the crank sensor or that water leak getting every thing wet??

It's a lot of work. I've rebuilt my engine.
It's just way too much info to put on the computer.
The best and easiest way for a Do-It-Yourselfer is to get a Chilton Manual for the autoparts store. It's cost about $20. It's will show you everything on how to do it step by step.

Here's what your look at to get the job done:
Removing the radiator, belts, pulleys, AC pump bracket (if it has AC), valve cover, distributor, and timing chain cover.

You'll have to replace:
Timing chain ( of course ), valve cover gaskets, timing chain cover gaskets, coolant, engine oil, and O-ring for the distributor.
It would be a good idea to replace the oil pump as long as you have everything part.
