Cover and Diaphragm Selection

Diameter: 57mm. Mercedes 1.5 DCI cover reference: 6070100300. Mercedes 1.6 OM626 cover references: 6260101300 and 6260104300. Additional exact forms: A6070100300, A6260101300 and A6260104300.

When to Inspect the Cover and Ventilation

• Oil leakage or seepage around the valve cover.
• Burning oil smell after the engine warms up.
• Air leaks through the cover or crankcase ventilation system.
• Unstable idle.
• Increased oil consumption.
• Whistling, excessive vacuum or mixture faults associated with leakage.

Diagnose the cover and crankcase ventilation system to establish the affected component before replacing the diaphragm.

Repair Scope

This is the diaphragm repair component, rather than a complete valve cover. Inspect the cover or oil separator housing, ventilation hoses and possible cracks. Diaphragm replacement may be suitable if the housing is intact; housing damage can require a different repair.

Important Before Ordering

Compare the original part number, marking, shape and mounting design before ordering. A model name alone does not confirm the required version.
