Withdrawal Disconnect the ventilation hose from the positive crankcase ventilation valve. Remove the valve from the cylinder head cover and connect it to the air hose.
Start the engine and let it run at idle. Close the finger valve hole and make sure that there is the presence of vacuum from the intake manifold (Fig. 2.352).
NOTE The plunger inside the valve body PCV should move back and forth. |
If vacuum is not felt, clean the PCV valve and breather hose in the cleaning solution (solvent) or replace if necessary.
Check Remove the PCV valve.
Insert a thin rod into the PCV valve from the threaded portion and check pozhvizhnost plunger (Fig. 2.353). If the plunger is stationary, the valve PCV has deposits. In this case, clean or replace the valve.
Setting Install the PCV valve and tighten it to the specified torque. Tightening torque PCV valve: 8-12 Nm.
