Mercedes Sprinter Timing Cover Cap with Seal – Genuine OEM | All Generations | #0000151200 (T1N / NCV3 / VS30)

A missing or degraded timing cover cap on a Mercedes Sprinter creates an unsealed opening in the timing cover — allowing oil to seep out and dirt, moisture, and debris to enter a cavity that houses timing components that cannot tolerate contamination. This is the Genuine Mercedes-Benz OEM timing cover cap with integrated seal, a direct replacement that restores the proper sealed closure for the timing cover access port across all Sprinter generations.

What This Part Does

The timing cover cap is a precision-fitted plug that closes an access or inspection opening in the engine's timing cover. The integrated rubber seal compresses against the timing cover bore when the cap is installed, creating a positive seal that prevents oil from weeping out and blocks external contamination from entering the timing cover cavity. On Mercedes diesel engines, these ports are used during engine assembly and service access — and the sealing integrity of each cap is important for maintaining the timing cover as a sealed, pressurized zone. When the cap's rubber seal hardens, cracks, or the cap itself is lost or damaged during a timing chain service or engine repair, the resulting gap is a reliable source of oil seepage that is often misdiagnosed as a gasket or seal failure elsewhere.

Common Symptoms of a Failed Timing Cover Cap

• Oil seeping or weeping from the timing cover area with no other identified seal failure
• Visible oil residue at the timing cover cap location after recent top-end engine work
• Cap found cracked, missing, or damaged during timing chain or valve cover service
• Intermittent oil smell from the engine bay traced to the front of the engine

When to Replace

Replace any time the timing cover cap is found cracked, brittle, or missing — particularly after timing chain service, valve cover work, or any repair that involves disturbing the front of the engine. This is an inexpensive part that is easy to overlook during reassembly and expensive to address after the fact if a seepage develops.
