Genuine Mercedes 000000-003495 Crankcase Breather Oil Drip Pan Bolt

The Genuine Mercedes-Benz 000000-003495 is the OEM retaining bolt for the crankcase breather oil drip pan found on a range of Mercedes-Benz engines. This factory-original fastener secures the oil drip pan to the camshaft housing as part of the crankcase ventilation system.

The crankcase ventilation system plays a critical role in engine health. Crankcase gases — a byproduct of normal engine combustion — are routed through an oil separator, which allows liquid oil to drain back into the oil pan while only gases continue into the intake system. The oil drip pan and its retaining bolt are key components in keeping this system sealed and functioning correctly. A failed or missing bolt can result in oil leaks, rough idle, hard starting, or check engine lights related to fuel trim and air measurement faults.

Important Installation Note: This bolt features a reverse (left-hand) thread. To remove, turn clockwise; to install, turn counterclockwise. Failure to account for this can result in stripped threads.

Key Features:

• Genuine OEM Mercedes-Benz factory part — exact fit and finish
• Reverse (left-hand) thread design — turn clockwise to remove
• Retains the crankcase breather oil drip pan to the camshaft housing
• Manufactured to original Mercedes-Benz specifications
• Direct OEM replacement — no modifications required

When servicing the crankcase ventilation system, it is recommended to inspect and replace this bolt along with the oil drip pan, seals, and O-rings as a complete repair to ensure a proper seal and prevent oil intrusion into the intake system.
