Title: How Could you Determine the Damaged PCV Valve in 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.
