Where is the PCV valve and hose located and how do you check it on 1997 through 2001 Toyota Avalon?

The PCV valve and hose is located in the valve cover. To check it, disconnect the hose and pull the PCV valve from the cover, then reconnect the hose. With the engine idling at normal operating temperature, place your finger over the valve opening. If there's no vacuum at the valve, check for a plugged hose or valve and replace any plugged or deteriorated hoses. After this, turn off the engine and remove the PCV valve from the hose. Blow through the valve from the valve cover (cylinder head) end. If air will not pass through the valve in this direction, replace it with a new one. To check the PCV valve, first attach a clean section of hose to the cylinder head side of the valve and blow through it - air should pass through easily - then blow through the opposite side of the valve and verify that air doesn't pass through it. When purchasing a replacement PCV valve, make sure it's for your particular vehicle and engine size. Compare the old valve with the new one to make sure they're the same.

Toyota Avalon PCV Valve

The PCV Valve is used in Toyota Avalon cars to enrich the functionality of its engine and, at the same time to reduce the amount of toxic gases which are emitted. They help to take partially burnt gases from the crankcase back to the combustion chamber where these are safe for ignition and thus reduces on the formation of oil sludge. It is a vacuum operated valve that closed gas flow at idle and opens at higher RPM for effective control of blow-by gases. Although the structure of the PCV Valve has not been changed between different models of Avalon, the state of the system should be controlled, because the broken valve can cause oil leakage, pollution, and enourmous fuel consumption. It is suggested that checks should be made periodically and the components that are likely to cause damage should be replaced often to ensure efficiency of the vehicle and to avoid encountering a huge bill in future.
