Where is a PCV valve located?
“PCV” stands for “positive crankcase ventilation.” It is a one-way valve attached to the crankcase. Your vehicle’s crankcase holds your motor oil, and is located at the bottom of your engine. It produces gases when your engine burns fuel.
What happens if PCV valve fails?
A bad PCV valve may have a leak, which will cause excessive oil consumption. This is because the pressure in the crankcase may increase when the PCV valve fails, so the oil is pushed out through the seals and gaskets since there’s no other way for the pressure to be released.
When should a Toyota PCV valve be replaced?
There is no specific lifespan for your car’s PCV valve. It lasts as long as it lasts. Regular maintenance will help provide a longer use life, while neglecting your regular oil changes will shorten it. Ideally, the PCV valve should be changed with every major scheduled service (30, 60, 90K, etc.).
Can you clean a PCV valve instead of replacing it?
Oftentimes, you’re better off simply replacing the valve which is difficult to clean even when removing it. However, there is one option you can try.
