What is the Most Common Positive Crankcase Ventilation (PCV) System Problem?
On modern cars, the PCV system (positive crankcase ventilation system) is essential to ensure that your car or truck starts when you are ready and maintains a durable and reliable vehicle. How does it work, and what are those purposes? What can go wrong? How to solve the problem of the PCV valve? SPELAB have those answers for you!
What exactly does it do?
Positive Crankcase Ventilation is a system that was developed to remove harmful vapors from the engine and to prevent those vapors from being expelled into the atmosphere.
The Positive Crankcase Ventilation (PCV) system reduces blowby emissions from the engine. The flow of fresh air through the crankcase helped pull moisture out of the oil to extended oil life and reduce sludge.
How does it work?
The system is simple. The PCV valve regulates how much vacuum can pull through the crankcase. It’s hooked into the intake - when the vacuum is high at idle, the PCV valve stops most of that vacuum. As vacuum drops with an increase in RPM, The PCV valve opens, to allow a higher volume of gasses and pressure to be pulled into the intake. As a result, those gasses are recirculated back into the combustion cycle, and burnt off with the fresh fuel and air, preventing those gasses from condensing in the oil, preventing pressure from causing the seals to leak, and preventing pollution from escaping the crankcase.
What problems will the neglected PCV system bring?
Like all automotive systems, the PCV system must be monitored and maintained. A neglected PCV system will soon fail to function and the result can be expensive as well as troublesome for the car owner. The gases flowing through your PCV valve leave traces of oil that can clog it up. Be sure to look out for symptoms of a damaged PCV valve, including:
1.Blown out seals or gaskets
2.Sludge around your engine
3.Noticeable oil leaks
4.Your check engine light is on
5.Whistling noises coming from the engine
Additionally, if your vehicle is idling roughly, your PCV valve could be to blame. Rough idling due to a damaged PCV valve, unfortunately, is often misdiagnosed as more expensive issues.
How to completely solve the problem of CCV / PCV?
Recommend you to use SPELAB CCV/PCV reroute kit. Originally, the blow-by gas in the crankcase enters the intake pipe, and then re-burns in the combustion chamber. After the modification, the blow-by gas will be directly discharged from the pipe to the atmosphere, returning to the most original design.
SPELAB CCV/PCV reroute kit exhausts crankcase pressure that eliminates the need for a restrictive baffle. Instead, it is intended to catch oil prior to the hose resulting in virtually no oil loss.
