Valve cover 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.

if the spark plugs are in the rocker cover , you will need new seals for them as well

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

You don't say what engine it has. The 4-cyl was a better than the V6 for oil leaks.

The V6 had oil leaks from

-rear bank cam cover gasket

-distributor o-ring seal

-oil filter bracket o-ring seal

-crankshaft nose oil seal (less common)

-rear main bearing oil seal (expensive, just leave it)

The 4 cyl leaked oil from

-distributor o-ring seal

-camshaft cover gasket

-rear main bearing seal (expensive, leave it)

Valve covers leaking oil OUT the tail pipe, no way in hell! Valve covers can leak oil onto the exhaust manifold, but there is no way its going to get into the exhaust from there and out the tail pipe.

Bad valve guides and/or valve guide seals would put oil from the top of the head and into the cylinders. That is a far bigger job than just replacing valve cover gaskets.

Don't let the warranty company give you any more of that kind of BS.

What kind of Mercedes is it ?
What size of the engine ?
On a 6.0L engine V12 , it is possibly crank ventilation valve assembly (oil separator), located on engine block valey.
V6 and V8 engines most likely valve cover gaskets.
Older ones , inline 6 cyl. engines - famos of leaking head gasket on a right rear corner.

Well the head gasket job will cover the valve cover gasket ( you have to do one to get to the other) Bring it to a repair shop its about a $1500 job.

The valve cover is located on the top side of this engine. It encloses the upper Cyl head that has oil spashing aroundin it from the valve train. If you have a coolant leak, it is either from the head gasket or the coolant block off plate in the back of the cyl head just under the Brake Master Cly. I hopes this helps answer your questions.
