Mercedes Sprinter Cylinder Head Gasket Set – Elring | NCV3 3.0L OM642 | #6420165120SET (2007–2022)

Replacing only one head gasket on the OM642 V6 while leaving the other bank's gasket in place is a reliable way to create a second head gasket failure within a short interval — on a V6 engine where both heads are accessed simultaneously for major service, replacing both gaskets at the same time with a complete set is the correct approach. This is the Elring cylinder head gasket set for NCV3 and VS30 Sprinters equipped with the 3.0L OM642 V6 diesel engine, a complete set covering both the left and right cylinder head gaskets plus associated sealing components for a single, complete top-end service.

What This Part Does

The cylinder head gasket set includes all gasket and sealing components needed for a complete OM642 top-end rebuild or dual-head service — the left bank head gasket (6420165120), the right bank head gasket (6420165220), and the associated valve cover gaskets, camshaft seals, and other top-end sealing elements included in the Elring full set. Each head gasket is a multi-layer steel construction that simultaneously seals combustion chambers, oil galleries, and coolant passages at each cylinder bank. Providing a complete set format ensures all sealing elements are renewed together, eliminating the situation where a partially serviced engine develops a new leak at an unserviced seal immediately after head gasket service is complete.

Common Reasons to Use the Full Set

• Complete engine overhaul requiring both heads to be removed
• Both head gaskets failing simultaneously from an overheating event
• Head gasket service where both heads are removed for valve work, timing access, or block inspection
• Preventive renewal of all top-end seals during a high-mileage engine rebuild

When to Use

Use whenever both cylinder heads are removed simultaneously. The set eliminates the need to source individual gaskets for each bank and ensures all sealing components are from the same Elring OE manufacturing specification.
