PCV valve location

The PCV valve should be located under hood, center, upper engine area, top of engine, mounted in driver side valve cover.

Check the PCV valve frequently to see if it is free and not gummed up, stuck or blocked. To check the valve, remove it from the engine and shake it. It should rattle. It is possible to clean the PCV valve by soaking it in a solvent and blowing it out with compressed air. This can restore the valve to some level of operating order.

This should be used only in emergency situations. Otherwise, the valve should be replaced at least once a year. Always check PCV valve hose for wear or cracks during service procedure.

Removal and installation:

Remove the PCV valve by simply disconnecting the vacuum hose from the valve, then pulling the valve from the rocker cover grommet.
