Can a bad PCV valve cause excessive oil consumption?
Excessive oil consumption and leak A bad PCV valve may have a leak, which will cause excessive oil consumption. In addition, you may also notice oil leaking through the seals and dripping on to the floor of your garage.
What happens when the PCV valve fails on a car?
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. The leak will cause your vehicle to burn oil and leak oil beneath your vehicle.
How does the PCV system separate the oil?
The valve cover has diffusers build into the top to separate the oil from the air before it goes into the PCV valve. The clean air intake usually does not have a baffle when entering. The PCV system in your car is designed to burn the blow by gasses that make it into the crankcase.
Why is there a spring in the PCV valve?
The PCV valve has a little spring in it to resist high engine vacuum during idle, deceleration, and cruising. The spring is there to prevent too much oil vapor from being sucked up into the intake and burned. If the spring fails, the engine will suck up too much oil and oil vapor and cause a low oil problem.

A clogged hose or PCV system or inoperative valve can increase oil consumption because pressure builds when the vapors in the crankcase aren’t allowed to flow into the combustion chambers. That additional pressure can force oil past seals and gaskets.
How much oil does a Nissan Versa use?
The Nissan Versa Tech Discussion forum is the place to discuss Versa performance modifications and maintenance. Oil consumption in between oil change..1/2 litre!! WHY? I just noticed that I have “consumed” 1/2 a litre of oil over the spand of an oil change.
What causes oil to come out of the PCV valve?
Another possiblility is the “blow by” created by the piston rings. If you throw your engine into a battle against another, more blow by is created, therefore, resulting in oil being recirculated into the intake system, in turn, consuming the oil. Check your PCV valve by putting it into your hand and shaking it like a rattle.
Why does my car use so much oil?
This is normal amongst many vehicle makes and models. Another possiblility is the “blow by” created by the piston rings. If you throw your engine into a battle against another, more blow by is created, therefore, resulting in oil being recirculated into the intake system, in turn, consuming the oil.
