VACUUM DELAY VALVE
Vacuum Delay Valve Inspection
- 1Blow air from the port of the distributor side. The valve is in good condition if the air flows through the valve.
SEF863H - 2Try again from the opposite side of the valve. The valve is in good condition if the air flow resistance is greater than in step 1 above.
CAUTION
Be careful to avoid entry of oil or dirt into valve.
ONE-WAY VALVE
One-Way Valve Inspection
- 1Blow air from the port of the intake manifold side. The one-way valve is in good condition if the air does not flow through the valve.
