The emergence of telltale signs which indicates that valve stem seals in your Volkswagen needs replacement should not be overlooked. Check the condition of those seals immediately and replace the damaged ones. To know more, please go through this slide.

1. VOLKSWAGEN VALVE SEAL
FAILURE: CAUSES AND SYMPTOMS

2. VALVES ARE
RESPONSIBLE FOR
REGULATING THE AMOUNT OF
AIR-FUEL MIXTURE WITHIN
THE COMBUSTION
CHAMBER.

3. IT ALSO HELPS TO
TRANSFER THE SPENT GASES
OUTSIDE THROUGH THE
EXHAUST SYSTEM.

4. THESE
vALVES ARE GUARDED BY
SEALS MADE UP OF SUPER-
STRENGTH RUBBER.

5. VALVE STEM SEALS
PREVENT THE LEAKAGE OF
COMBUSTION GASES AND
THUS MAINTAIN
COMPRESSION WITHIN
THE ENGINE.

6. MOREOVER, IT
ALSO PREVENTS OIL
FROM LEAKING INTO
THE COMBUSTION
CHAMBER.

7. HOWEVER, A
DAMAGED VALVE STEM
SEAL COULD NOT DO ITS
JOB WHICH COULD
ADVERSELY AFFECT THE
ENGINE PERFORMANCE.

8. WHAT
CAUSES VALVE
STEM SEALS TO
FAIL?

9. FOLLOWING
FACTORS ARE RESPONSIBLE
FOR THE DETERIORATION OF
VALVE SEALS IN YOUR
VOLKSWAGEN:
• HEAT GENERATED DUE TO THE
COMBUSTION PROCESS
• AGING

SEALS

12. WORN-OUT
VALVE SEALS
COULDN’T MAINTAIN
COMPRESSION WITHIN
THE COMBUSTION
CHAMBER.

13. LACK OF COMPRESSION COULD ADVERSELY
AFFECT THE POWER OUTPUT OF AN INTERNAL
COMBUSTION ENGINE.

15. 14
VALVE
SEALS PREVENT THE SEEPAGE OF MOTOR
OIL INTO THE COMBUSTION CHAMBER.

16. HOWEVER,
A DETERIORATED VALVE
SEAL FAILS TO DO SO AS
A RESULT OF WHICH OIL
CONSUMPTION
WOULD INCLINE.

18. LEAKAGE OF MOTOR OIL INTO THE COMBUSTION
CHAMBER DUE TO WORN OUT VALVE STEM SEALS
COULD GENERATE THICK BLUE SMOKE.

19. REPLACE
THE DAMAGED SEALS AS
SOON AS POSSIBLE.

20. S T R A N G E
E N G I N E N O I S E

21. STRANGE TICKING AND POPPING NOISES FROM
THE ENGINE INDICATE THAT VALVE SEALS ARE
DETERIORATED AND NEED REPLACEMENT.

22. SUM UP

23. THE CONDITION OF VALVE STEM SEALS IN YOUR
VOLKSWAGEN SHOULD BE INSPECTED
REGULARLY.

24. DAMAGED
ONES SHOULD BE REPLACED IMMEDIATELY.
