PCV Valve Removal and cleaning



A dirty or failed PCV valve can cause excessive oil usage,(Which early 2000-2002 1ZZ-FE engines are prone to anyway!), and worse still cause sludge build-up; Sludge is an engine killer! The PVC system recirculats gaseous contaminants back into the combustion process, contaminants which would otherwise cause the oil to.
To remove the PCV valve, remove the cosmetic cover by removing the two 10mm nuts and two plastic pull out retainers. Once the cosmetic cover is off, you will see the PCV valve at the back right side of the top of the engine, squeeze the spring retaining clip and pull of the rubber hose. Then using a deep 19mm socket and a wench with some leverage, unscrew the PCV valve.
Once it's out, shake it, it should rattle as the valve moves if it's good! If it doesn't rattle it may have failed. Spray lots of carb. cleaner through the valve then reinstall it.
