Mercedes-Benz Oil Tank Caps
M&B Parts supplies high quality Mercedes-Benz oil tank caps designed to seal the engine oil system correctly and prevent oil leaks, vapour escape, and contamination. A properly functioning oil cap is essential for maintaining crankcase pressure and keeping the engine bay clean.
We stock oil tank and oil filler caps for a wide range of Mercedes-Benz models, offering correct thread design, sealing materials, and long term durability.
Oil Tank Caps for Mercedes-Benz Engines
The oil tank or oil filler cap seals the engine oil reservoir and prevents oil from escaping during engine operation. It also helps regulate internal pressure within the crankcase.
Using a worn or incorrect oil cap can result in oil leaks, oil smells inside the cabin, and engine management issues caused by vacuum leaks.
What Does a Mercedes Oil Tank Cap Do
The oil tank cap seals the oil filler opening and prevents dirt, moisture, and debris from entering the engine. On many Mercedes-Benz engines, the cap also plays a role in maintaining correct crankcase pressure.
Over time, rubber seals inside the cap can harden, crack, or lose elasticity, reducing sealing effectiveness.
Common Signs of Mercedes Oil Tank Cap Failure
A faulty oil tank cap may present one or more of the following symptoms:
-
Oil residue around the filler neck
-
Burning oil smell from the engine bay
-
Whistling or vacuum noises
-
Check engine light in some cases
-
Oil contamination
Replacing a worn oil cap is a simple and cost effective way to prevent further engine issues.
