How Long Does a Vent Oil Separator Last?

The engine in your car can only run when the right number of controlled explosions are performed. During the explosions, there are a number of gases that are produced that will then be filtered out of the engine. The exhaust gases are released through the manifold system and are then pushed out the back of your car’s tail pipe. The blow-by gas that is produced during these explosions can be very harmful to the engine, which is why there are a number of components that are in place to keep it at bay. The vent oil separator helps to collect the oil that is produced by this harmful gas to keep it out of the crankcase.

With all of the different issues that can arise with this part of a car, it is a good idea to keep an eye out for signs of trouble. In some instances, there will be too much oil in this separator and it will start to cause the engine to misfire. If the vent oil separator becomes clogged in any way, then it will lead to excessive pressure in the engine. This high level of pressure can lead to a seal being blown in your car’s crankcase.

During colder parts of the year, the vent oil separator will have more trouble doing the job it is intended for. In some instances, problems with other components of the crankcase ventilation system can mimic issues with the vent oil separator. When in doubt of what is causing the issues you are experiencing, you will need to find a professional to give you a hand. They can diagnose and fix your vent oil separator or your crankcase ventilation system to ensure your vehicle is in top shape for optimal driving.

The following are a few of the issues that may arise when this part of your car is in need of repair:

  • There is oil in the PCV valve
  • There is blue smoke coming from the exhaust
  • The engine is running very rough

Addressing the issues that you have with your vent oil separator will allow you to restore the functionality that you have lost.

Audi Q7 V8-4.2L - Vent Oil Seperator - Chicago, Illinois
Rigoberto is a very knowledgeable mechanic. He fixed my Audi Q7 and I ended saving money compared to taking it to the dealer. He was on time and very friendly, I would book him again and recommend him to friends and family.

Great effort to find problem, but missed real problem. Porsche is different than most autos. Problem was a cooling valve for transmission. Had a air leak. Needed Porsche experience I guess. Thanks Ken m.

Volvo S40 L5-2.5L Turbo - Vent Oil Seperator - Davenport, Florida
Enrique was very friendly, professional, and positive! He provided excellent customer service, like a doctor with the ideal bedside manner. Examples of this are that he patiently listened to me, showed me the issues my car was having (which has happened maybe only once or twice in the 25 years I've been driving), and he explained to me the way it would affect the vehicle. He was the best service adviser and mechanic I've ever had.
