Frequently Asked Questions
- ❓ What does "valve cover gasket" exactly cover?
- This term generally refers to the gasket located between the valve cover and the cylinder head body. It acts as a barrier against the leakage of engine oil, vapor, and dirty air.
- ❓ Is the part code ELRING 820.093 reliable?
- Yes — ELRING is an OEM-level part manufacturer. However, it may not always be clear in catalogs that this code is valid for all versions of the W124 model. Therefore, please check compatibility with your vehicle's chassis number, engine code, and original part number.
- ❓ When should this gasket be replaced?
- Replacement is typically considered when signs such as oil leakage around the oil chambers, vapor around the valve cover, or contamination in the upper part of the engine are observed. Additionally, if the cylinder head has been removed, it should be installed with a new gasket.
- ❓ Are there any considerations to keep in mind during installation?
- Yes — the cylinder head surface must be flat and clean, old gasket remnants must be completely removed, and the cover bolts should be tightened according to the manufacturer's torque specifications. Otherwise, sealing cannot be achieved.
Installation Notes
- The engine should be cold before installation, and the environment should be kept clean.
- Old gasket remnants should be carefully cleaned, and if there are scratches or deformations on the surface, it should be leveled.
- When placing the new gasket, alignment should be done according to the instructions, and the cover should be sealed tightly.
- After installation, the engine should be started to check oil level, sealing, and vapor emission.
Note
Although these types of sealing elements may seem small, they are critical for the health of your engine. An improper or damaged valve cover gasket can lead to performance loss due to oil and vapor leaks, engine contamination, and serious damage in the long run. Therefore, it is important to choose a quality and compatible part like Mercedes W124 M104 Valve Cover Gasket | ELRING 820.093.
