Blue smoke from a vehicle’s exhaust is a sign of inconvenience. It is important to comprehend what blue smoke means so that fixing can be straightforward. If the vehicle’s engine burns too much oil, then it will give rise to the emission of blue smoke. Presence of dirt and sludge accumulation can cause blue smoke. So, try to keep the engine clean, avoid keeping bad glow plugs, fix the blown turbo on time, keep the transmission modulator in good condition- that will help you to overcome blue smoke issues.

1. WHAT DOES BLUE SMOKE FROM THE
EXHAUST OF A CAR MEAN?

2. Color of the smoke
emitted from the
exhaust system of a car
shows the health of an
engine.

3. Appearance of blue
smoke from the exhaust
pipe of a car clearly
indicates that lubricant
is entering the
combustion chamber of
the engine.

4. Lubricant used in the
engine helps to reduce
friction among different
components of the
engine and also
prevents engine
overheating.

5. However, lubricant
should not enter the
combustion chamber of
the engine as it could
disrupt the power
generation process.

6. So, mechanical
deformities responsible
for the leakage of
motor oil into the
combustion chamber
needs to be identified
and repaired in time.

7. REASONS FOR BLUE
SMOKE

8. Intake and exhaust
valves of an engine play
vital roles to keep the
engine operational.
DETERIORATED VALVE
SEALS

9. These valves help to
provide the required
amount of fuel and air
into the combustion
chamber as well as also
helps to get rid of the
byproducts of internal
combustion.

10. Valve seals prevent the
leakage of oil into the
combustion chamber of
the engine.

11. However, deteriorated
or deformed valve seals
fail to do so which
could impair an engine.

12. The primary job of the
positive ventilation
system is to get rid of
the blow by gases from
the crankcase.
FAULTY PCV VALVE

13. The PCV valve helps to
introduce the blow by
gases through the air
filter to the intake
manifold which again
enters the combustion
chamber.

14. However, a faulty or
stucked PCV valve fails
to regulate the flow of
blow by gases which
could be responsible for
the emission of blue
smoke.

15. So, the condition of the
PCV valve should be
inspected regularly.

16. Pistons which are
considered as the
backbones of an engine
helps to transfer the
mechanical energy to
the crankshaft.
DAMAGED PISTON RINGS

17. Piston rings prevent
the leakage of motor oil
into the combustion
chamber of the engine.

18. However, damaged
rings fail to do so as a
result of which motor
oil enters the
combustion chamber
and generates blue
smoke.

19. Leakage of transmission
oil into the combustion
chamber also generates
blue smoke.
TRANSMISSION OIL
LEAKS

20. BOTTOM LINE

21. Color and quantity of
the smoke emitted
from the engine helps a
lot to analyze the
condition of the engine.

22. Such kinds of warning
signs should never be
neglected.
