The document discusses the primary job of a positive crankcase ventilation (PCV) system and signs that the PCV filter is clogged or defective. The PCV system removes blow-by gases from the crankcase and returns them to the combustion chamber, preventing air pollution and improving efficiency. A clogged or damaged PCV filter can negatively impact performance by restricting blow-by gas flow and disrupting the fuel-air ratio, which can cause issues like engine oil leakage, poor engine performance, and unburned hydrocarbons in the exhaust. The document stresses that signs of a failed PCV filter should not be ignored and filters should be cleaned or replaced when clogged.

2. The primary job of a positive
crankcase ventilation system or PCV
is to get rid of the blow-by gases from
the crankcase and reuse such gases in
the combustion chamber.

3. By doing so, it prevents air pollution
as well as also increases the efficiency
of the engine.

4. Any kinds of mechanical failures in
such an important system might have
disastrous consequences.

5. Blow by gases enters the combustion
chamber through a filter which helps
to get rid of the contaminants.

6. Clogged or damaged PCV filter might
affects the performance of a car in a
very adverse way.

7. So, everyone should be aware of the
early warning signs of a clogged or
failed PCV filter in a car in order to
spot and fix the problems in time.

9. Blow by gases could not pass through
the contaminated or clogged filter
which could build up pressure inside
the crankcase.
ENGINE OIL LEAKAGE

10. Higher pressure inside the crankcase
would damage the oil pan gasket.

11. So, engine oil leakage is an early
warning sign of a clogged PCV filter in
a car.

12. Such warning signs should not be
ignored.

13. Clogged or defective PCV filter could
affect the fuel to air ratio inside the
combustion chamber of an engine.
POOR ENGINE PERFORMANCE

14. The presence of a disproportionate
amount of fuel or air inside the
combustion chamber could adversely
affect the power output of an engine.

15. So, if the engine is not making the
required quantity of acceleration,
then it clearly indicates that
something is not right and needs
immediate attention.

16. The primary function of the PCV
system is to divert the blow by
unburned hydrocarbons to the
combustion chamber instead of the
exhaust system.
UNBURNED HYDROCARBONS
IN THE EXHAUST GASES

17. However, clogged or defective PCV
filter fails to do its job.

18. So, the presence of an excess amount
of unburned hydrocarbons in the
combustion chamber should not be
neglected.

20. Deposition of contaminants on the
PCV filter could jeopardize the
engine.

21. So, signs of a failed PCV filter should
not be ignored.

22. Efforts should be made to keep the
filter clean and clogged filters should
be replaced immediately.
