The PCV valve reroutes blow-by gases from the crankcase to the combustion chambers. By doing so, it stabilizes pressure within the crankcase and prevents sludge formation. Moreover, it also reduces the level of exhaust emission. Faults in such a vital component could bring your BMW X3 to a halt in the middle of nowhere. So, signs of a failing PCV valve should not be overlooked. This graphical presentation might be useful for you.

VALVE IN BMW X3 IN SPRING
CYPRESS RD

2. THE MAIN JOB OF A PCV VALVE IS
TO REMOVE THE BLOW-BY GASES
FROM THE CRANKCASE IN ORDER
TO PREVENT SLUDGE FORMATION.

3. IT REROUTES THOSE GASES TO THE
COMBUSTION CHAMBER TO
MINIMIZE THE LEVEL OF EXHAUST
POLLUTION.

4. HOWEVER, A FAILING PCV VALVE
COULD JEOPARDIZE THE POSITIVE
CRANKCASE VENTILATION SYSTEM
OF YOUR BMW X3.

5. SO, THE EMERGENCE OF DIFFERENT
TYPE OF SIGNS WHICH SHOWS
THAT THE PCV VALVE IS GOING BAD
SHOULD NOT BE IGNORED.

6. HAVE A LOOK AT SOME OF THE
MOST COMMON SYMPTOMS OF A
BAD PCV VALVE IN YOUR BMW X3.

7. SIGNS OF BAD PCV
VALVE

9. LEAKAGE OF MOTOR OIL IS A TELL-
TALE SIGN OF A FAILING PCV
VALVE.

10. PCV VALVE HELPS TO STABILIZE
THE PRESSURE WITHIN THE
CRANKCASE BY REMOVING THE
BLOW-BY GASES.

11. HOWEVER, A FAILING PCV VALVE
FAILS TO DO SO AS A RESULT OF
PRESSURE WITHIN THE CRANKCASE
WOULD INCLINE THAT COULD
CAUSE A MOTOR OIL LEAK.

13. FORMATION OF AN EXCESS
AMOUNT OF SLUDGE WITHIN THE
CRANKCASE DUE TO A DAMAGED
PCV VALVE COULD AFFECT THE
PERFORMANCE OF THE ENGINE.

14. SO, POOR ENGINE PERFORMANCE
IN YOUR BMW X3 IS A SIGN OF A
FAILING PCV VALVE.

16. FAULTY PCV VALVE ADVERSELY
AFFECTS THE PERFORMANCE OF
YOUR BMW X3.

17. WHEN THE ECU DETECTS ANY KINDS
OF ABNORMALITIES, IT WOULD
WARN THE DRIVER BY TURNING ON
THE CHECK ENGINE LIGHT ON THE
DASHBOARD.

19. IF YOUR BMW X3 IS EXPERIENCING
ENGINE MISFIRE, THEN IT SHOWS
THAT THE PCV VALVE IS FAILING.

20. SO, CHECK THE CONDITION OF THE
PCV VALVE IMMEDIATELY AND
REPLACE IT IF NECESSARY.

22. EMISSION OF THICK BLUE EXHAUST
SMOKE IS ALSO A SIGN OF A
FAILING PCV VALVE.

23. SO, CHECK THE CONDITION OF
THOSE COMPONENTS IMMEDIATELY
AND REPLACE THEM IF NECESSARY.

24. WRAPPING UP

25. SYMPTOMS OF A FAILING PCV
VALVE IN YOUR BMW X3 SHOULD
NOT BE OVERLOOKED.

26. EFFORTS SHOULD BE MADE TO
IDENTIFY AND REPAIR THE DEFECTS
IN THOSE COMPONENTS.
