Valve Cover Oil Separator - Opel GM - for 55596087

This oil separator is a separate valve cover repair component for the listed Opel and GM applications. Match the original valve cover number before selecting it; the original assembly offering does not supply the separator separately.

Applications

• Opel ASTRA-K (B16).
• Opel INSIGNIA-B (Z18).

Cover and Engine Selection

Engine context: A16SHT, A16XHT, B16SHL and B16SHT; additional exact lowercase form: a16sht. Cover references: 5607229, 607758, 55596087, 55569822, 55590970 and 55590969. Match the original cover and separator design.

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

The separator is the replacement component, rather than the complete valve cover. Inspect a dried or torn diaphragm working edge, housing, ventilation hoses and cracks. The cover housing must be serviceable; housing damage can require another 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.
