Identifying Early Warning Signs Of AOS Failure In Porsche Models

As a Porsche owner, itu2019s essential to recognize signs of Air-Oil Separator (AOS) failure to maintain performance. Key indicators include oil leaks, unusual exhaust smoke, sluggish engine response, increased crankcase pressure, oil contamination, strange noises, and a check engine light. Proactive monitoring can prevent costly repairs and ensure smooth operation.

  1. Identifying Early Warning Signs Of AOS Failure In Porsche Models

  2. Porsche… the speed machine that every car enthusiast dreams of owning. • But acquiring such a high-end vehicle has its own set of challenges.

  3. Some of the issues in Porsche models are quite expensive to repair. Today’s presentation is about one such issue… AOS failure.

  4. AOS: What You Need To Know As A Porsche Owner

  5. AOS or Air-Oil Separator… is basically an emissions control unit in a Porsche. • It does exactly what its name implies―it separates oil vapor from the crankcase emission.

  6. The separated oil vapor will then be condensed and directed back into the oil sump.

  7. Remaining gases (mostly combustion gases) will be conveyed to the engine’s intake system.

  8. By doing so, the AOS… Prevents unnecessary wastage of oil Improves engine efficiency Reduces harmful emissions Protects engine parts from oil fouling Enhances engine longevity If it malfunctions, the impact will be widespread…

  9. Why Your Porsche’s AOS Might Fail

  10. There can be many reasons… The below discussion sheds light on seven prominent ones. #1- Oil contamination #5- Driving conditions and habits #2- Thermal stress #6- High mileage #3- Excessive engine pressure #7- Clogged filter, etc. #4- Improper installation

  11. Tell-Tale Signs You Shouldn't Ignore

  12. #1- OIL LEAKS

  13. Has your Porsche been leaking oil from the engine area lately?

  14. One likely explanation is that… its air-oil separator is struggling to contain oil effectively. • Most probably, because of seal deterioration.

  15. #2- UNUSUAL EXHAUST SMOKE

  16. Dense blue smoke emerging out of your Porsche exhaust?

  17. It points to one thing… oil has somehow entered the combustion chamber and it’s burning there.

  18. It could be due to a damaged gasket/seal, a clogged oil filter, or a faulty air-oil separator.

  19. #3- SLUGGISH ENGINE PERFORMANCE

  20. One common occurrence in Porsche cars with defective air-oil separator is reduced engine performance.

  21. A defective AOS can destabilize air-to-fuel proportion inside the cylinder.

  22. Which can contribute to all sorts of drivability issues in the vehicle… including sluggish acceleration.

  23. #4- INCREASED CRANKCASE PRESSURE

  24. Pressure inside your Porsche’s crankcase will skyrocket… if its AOS is faulty. • Increased pressure can contribute to premature seal and gasket blow outs.

  25. If left unchecked―this abnormal oil pressure fluctuation can result in expensive repairs down the road.

  26. #5- CHECK ENGINE LIGHT

  27. Last… but the most obvious one on the list. • Retrieve the error code stored in the fault memory and proceed accordingly.

  28. CONCLUDING REMARK

  29. Air-oil separator dampens crankcase emissions in some of the renowned Porsche models.

  30. Failure of such a crucial component can contribute to all sorts of drivability problems.

  31. Efforts should therefore be made to diagnose and fix such issues on time.
