Mercedes Sprinter Oil Filter Housing Gasket – Elring | NCV3 & VS30 3.0L OM642 | #6421840080 (2007–2022)

Replacing the oil filter housing on a Sprinter OM642 without renewing this gasket is one of the most reliable ways to immediately create an oil leak at the housing-to-block interface — and on an engine where the oil filter housing is also integrated with the oil cooler circuit, a failed seal here means an oil leak that can migrate onto the exhaust and hot engine components below. This is the Elring oil filter housing gasket for NCV3 and VS30 Sprinters equipped with the 3.0L OM642 V6 diesel engine, a direct replacement that restores a proper sealed interface between the oil filter housing and the engine block.

What This Part Does

The oil filter housing gasket seals the flanged mating surface between the oil filter housing assembly and the engine block. The OM642's oil filter housing is a complex component that integrates the oil filter mount, oil cooler passages, and oil pressure regulation circuitry — all of which share a common sealed interface at the block. The gasket maintains the pressure boundary at this junction, preventing engine oil from escaping at the housing perimeter and preventing oil from migrating into the coolant passages within the housing assembly. The gasket is exposed to sustained oil pressure and repeated thermal cycling from cold starts to operating temperature, causing the sealing material to compress and eventually lose its ability to maintain the required contact pressure. A hardened or compressed gasket that is reused after housing removal will not seal reliably, regardless of torque specification.

Common Symptoms of a Failing Oil Filter Housing Gasket

• Oil seeping or dripping from the base of the oil filter housing or its perimeter seam
• Oil residue or accumulation on the engine block below the filter housing
• Burning oil smell from oil dripping onto the exhaust manifold or downpipe
• Gradual oil level drop without obvious external leak elsewhere on the engine
• Oil-coolant contamination if the internal seals within the housing have also failed

When to Replace

Replace any time the oil filter housing is removed — for oil cooler service, housing cleaning, or any other repair that requires breaking the housing-to-block seal. Never reinstall the housing on a used gasket. Also replace when oil seepage is confirmed at the housing perimeter during inspection.

NCV3 & VS30 OM642 Specific — VIN Verification Required
