PCV System (V6): Diagnosis Honda Accord VIII

PCV Valve Inspection

1. Remove the engine cover (see step 2 under «INTAKE MANIFOLD REMOVAL AND INSTALLATION»(ref-423685-S35751896362011092800000) ).
2. Check the PCV valve (A), hoses (B), and connections for leaks or restrictions.
3. At idle, listen to the PCV valve (A) with a stethoscope as you lightly pinch the PCV hose (B) with your fingers or pliers several times. Each time the hose is pinched, the valve should click.

If there is no clicking sound, check the PCV valve collar and O-rings for cracks or damage. If they are OK, replace the PCV valve (see PCV VALVE INSPECTION ) and recheck.
