The PCV valve in cars ensures that there is a clean emission system. Therefore, it is important to know the signs like poor fuel economy, stalling of an engine, oil leakage and sludge that may lead to a faulty PCV valve. Go through the given slides to know more about how to determine the damaged PCV valve in a car.

1. How Could you
Determine the
Damaged PCV Valve
in Car

2. If you want a clean
emission system in your
car, then you need to have
a fully functional PCV
valve system in your car.

3. But, over time the PCV
valve system of your car
is damaged or worn out
when they are used for
several years.

4. Before you replace the
damaged PCV valve of
your car, it's your
responsibility to
recognize the symptoms
of a damaged PCV valve
in your car.

5. If you ignore the signs
of a damaged PCV
valve, then it could
make a irreversible
damage in the engine.

6. Here the points provide
all the basic symptom of
a damaged PCV valve in
your car.

7. Check engine light

8. When the PCV valve is
damaged, then either too
much air or fuel enter the
combustion cylinder of the
engine.

9. The sensor relays the
information back to the
control unit after the ignition
of air and fuel mixture and
cause the check engine light
to illuminate on the
dashboard.

10. Poor fuel economy

11. If the PCV valve of the car
is closed, then it will
create a mixture of air and
fuel in the combustion
cylinders.

12. If more fuel is consumed
by your car, then it will
damage the fuel economy
and forces you to pay more
on your gas and more
emission as well.

13. Engine stalling

14. The PCV valve of your car
has a plunger which
could stay open when it is
damaged. As a result, an
excessive amount of air
will flow into the
combustion cylinders.

15. In this way, it will lean the
mixture of air and fuel
because the air is more than
the fuel in the cylinders and
caused engine stalling or
rough idling.

16. Oil leakage

17. When the PCV valve is
damaged or just wear out,
then it is unable to get out
of the closed position
because it is stacked.

18. If you put more pressure in
it, the higher chance of oil
leak occurs in the seals and
gaskets. The air cleaner
assembly may have oil
leaks as well.

19. Sludge

20. When the toxic gases
from the combustion start
leaking out into the
middle of the cylinder
wall and piston, they will
mix with the oil in the
engine.

21. Due to the mixture of oil
and exhaust gases cause
sludge residue and build
up until it damages the
engine.
