When to Inspect the Diaphragm

• Whistling or excessive crankcase vacuum.
• Unstable idle.

• Oil deposits in the intake.
• Exhaust smoke after warm-up.
• Mixture faults associated with air leaks.

Inspect the ventilation system and engine to establish the cause; these symptoms do not prove that the diaphragm alone is faulty.

Repair Scope

Inspect the valve cover or oil separator housing and ventilation pipes for cracks and damage. A diaphragm replacement may be sufficient when the housing is sound; damaged surrounding parts require separate attention.
