Valves and valve seals regulate fuel/air flow and timing into the combustion chamber. Valve seals prevent oil leakage into the chamber and maintain compression. Deteriorated seals cannot perform these functions, leading to issues like blue smoke from the exhaust due to oil leakage into the chamber. Damaged seals also cause poor engine performance from loss of compression and increased oil consumption. Abnormal signs from the engine should not be ignored so seal problems can be detected and fixed in a timely manner to keep the engine functioning properly.

2. Valves not only regulate the
quantity of fuel and air mixture
allowed in the combustion
chamber of a cylinder, but also
controls the timing of injection.

3. Valve seals which are made of
high quality rubber prevents
the leakage of engine oil into
the combustion chamber of the
engine.

4. Besides, valve seals also
maintain the compression
inside the combustion chamber
of the engine.

5. However, deformed or
deteriorated valve seals could
not do so which could adversely
affect the power output of an
engine.

7. Emission of thick blue smoke
from the exhaust pipe is a clear
sign of deformed valve seals.
EMISSION OF BLUE
SMOKE

8. Leakage of motor oil into the
combustion chamber is solely
responsible for the emission of
blue smoke from the exhaust
pipes.

9. So, the color and quantity of
smoke emitted from the
exhaust pipe should be
analyzed regularly.

10. Such kinds of analysis helps to
detect and fix the problems in
time.

11. As mentioned earlier, valve seal
plays a crucial role to prevent
any loss of compression.
POOR ENGINE
PERFORMANCE

12. However, damaged valve seals
fail to do so as a result of which
compression inside the engine
declines and so does the power
output.

13. So, if the engine fails to
generate the acceleration, then
it should not be overlooked.

14. Low oil pressure and higher oil
consumption are some of other
signs of defective valve seals in
a car.
OIL CONSUMPTION
INCREASES

15. So, the quantity of motor oil
should be inspected regularly
and a sudden reduction of oil
level should not be neglected.

16. Such problems should
never be neglected.

17. It is a major problem during
the winter months and
defective or worn out valve
seals are solely responsible for
such problems.
COLD ENGINE

19. Valve seals play a crucial role in
the performance of an engine.

20. Any kinds of defects in such
crucial components might
jeopardize the engine.

21. So, the appearance of abnormal
signs which shows that the
valve seals have some issues
should not be neglected.

22. Worn out valves should be
replaced in time in order to
keep the engine in working
order.
