When to Inspect PCV

• Whistling or excessive crankcase vacuum.
• Unstable idle.
• Increased oil consumption.
• Oil deposits in the intake.
• Exhaust smoke after warm-up.
• Mixture faults associated with intake air leaks.

Check the diaphragm, housing and ventilation pipes to confirm the cause before repair.

Repair Scope

This is the separate diaphragm, rather than a complete housing. Inspect the housing and ventilation pipes for cracks or damage; a damaged housing may require additional 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.
