Since no one seems to click on "links"...

Once again click here...

The PCV valve is perhaps the oldest emissions control component to be installed on production cars and light trucks. The PCV routes partially burned gases (called "cylinder blowby gases") from the crankcase back into the air induction system, where they're reburned in the combustion chamber.

Over time, oil and gasoline build up as sludge inside the PCV valve assembly, plugging up the valve and increasing crankcase pressure. A worn PCV valve or breather element causes heavy engine sludging, poor engine performance and stalling. Symptoms of PCV valve deterioration include:

Excessive oil consumption and leakage. The increased crankcase pressure forces oil through seals and gaskets.

Air filter contamination. The increased crankcase pressure forces PCV vapors through the breather element, depositing oil and hydrocarbon particles on the air filter itself.

Poor idle quality and hesitation. A sticking PCV valve does not fully close, allowing "false air" into the combustion chamber that dilutes the air/fuel mixture.

Most manufacturers recommend replacing the PCV valve every 30,000 miles. However, check for signs of a plugged or sticking valve when you're inspecting the air filter and engine compartment.

Or, like said, you could just clean it and pay nothing...

sends fuel fumes back into the intake to be reburned again

crank case gasses. pcv=positive crancase ventilation.

where do you think these gases come from?

yes, take the two bolts/screws off and lift the plate up and you will see the pcv valve in there, just pull it out of the intake and install the new one

Clean off the spring in there too, if necessary.
