Mercedes Sprinter Rear Crankshaft Seal Cover – Elring | VS30 2.0L OM654 Diesel | #2540100301 (2023+)

A leaking rear crankshaft seal cover on a VS30 Sprinter will deposit oil on the bellhousing, transmission, and surrounding components — making a mess that's easy to ignore until the oil loss becomes significant enough to cause engine damage. This is the Elring rear crankshaft seal cover for VS30 Sprinters equipped with the 2.0L OM654 diesel engine, a direct replacement that restores the sealed rear crank exit point and stops oil from migrating into the drivetrain.

What This Part Does

The rear crankshaft seal cover mounts to the rear face of the engine block and houses the rear main radial shaft seal — the critical sealing element that prevents engine oil from escaping along the crankshaft as it exits the block toward the flywheel and transmission. The cover provides the precise bore and mounting surface the seal requires to maintain contact with the rotating crankshaft snout under all operating temperatures and pressures. On the OM654, the rear seal cover is replaced as a complete assembly rather than the seal alone, ensuring the sealing bore geometry is correct and eliminating the risk of seal damage during installation. When the cover warps, cracks, or its integrated seal degrades, oil seeps along the crankshaft and accumulates at the rear of the engine — often pooling at the transmission bell housing where it is mistaken for a transmission leak.

Common Symptoms of a Failing Rear Crankshaft Seal Cover

• Oil accumulation at the rear of the engine block or on the transmission bell housing
• Oil drips or puddles beneath the van concentrated toward the center or rear of the engine
• Oil smell from under the vehicle during or after driving
• Oil residue on the flywheel or clutch components found during transmission removal
• Gradually dropping oil level with no visible leak at the top or front of the engine

When to Replace

Replace when rear main seal leakage is confirmed and traced to the rear crankshaft seal cover. Also replace whenever the transmission or flywheel is removed — the rear seal cover is fully accessible at that point and replacing it eliminates the risk of a repeat leak that would require another transmission-out job to address.

VS30 OM654 Specific — VIN Verification Required
