When to Inspect the Membrane

• Oil leakage or misting around the valve cover.
• A burnt-oil smell after the engine warms up.
• Unmetered air through the cover or crankcase ventilation system.
• Unstable idle.
• Increased oil consumption.
• Whistling, abnormal vacuum or mixture faults linked to an air leak.

Inspect the cover, membrane and ventilation system to identify the source of the fault. These symptoms do not confirm that the membrane alone needs replacement.

Repair Scope

The diaphragm can be serviced separately when the surrounding cover and housing are sound. Inspect the other sealing components before choosing the repair; replacing a membrane does not correct damage elsewhere in the assembly.

Important Before Ordering

Compare the installed assembly reference, membrane design and dimensions before ordering. Check the housing and ventilation hoses for damage; a membrane alone may not resolve a cracked housing.
