Mini Cooper Countryman

Mini Coopers were designed with a performance engine in a compact and fun model. Minis are also safe and roomy on the inside.

The best way to keep your Mini in the best condition is by keeping a proper maintenance schedule. Even with this schedule, there are going to be other parts and systems that require further care. One such system is the PCV system. Continue reading to find out the function of the PCV system, what signs to look for if it needs to be replaced, and where to go to get it replaced.

The Function of the PCV System

The Positive Crankshaft Ventilation (PCV) system is responsible for ensuring that the gases emitted from the engine are properly recycled.

The most important part of the PCV system is the PCV valve. The PCV valve is the main component that controls the blow-by gases. Using the engine vacuum, the PCV valve pulls the blow-by gases out of the crankcase. Once the gases are out of the crankcase, the PCV valve pushes the blow-by gases down the intake manifold and back into the combustion chamber. Back in the combustion chamber, these blow-by gases are re-burned and reused by your Mini’s engine.

The PCV system should be properly maintained at all times because it ultimately helps in keeping the atmosphere clean. When fewer engine gases are emitted from your Mini, less damage is caused to the atmosphere and the environment around us.

The PCV system also helps to make your Mini more efficient. With the ability to reuse these gases, less fuel will be used when driving so you can go longer without needing to fill up your tank.

Common Signs of a Failing PCV System

The PCV system is one that needs to be properly taken care of to protect your Mini, your wallet, and the environment. The best way to keep the PCV system up and running is to know what signs to look for when it is starting to fail. Knowing the signs will help you to bring in your Mini quickly so replacements can be made sooner rather than later.

The first sign of a failing PCV system is the check engine light. Your Mini contains a computer that is responsible for sending and receiving signals to a majority of its parts. The PCV system is monitored by the computer through the surrounding sensors. When the sensors pick up an issue with the PCV system, they report this to the computer and the computer alerts you via the check engine light on the dashboard.

It is important to always be mindful of this warning light, because the issue could be the PCV system or it could be something even worse. So it is best to not continue driving your Mini for an extended time with the check engine light on.

The second sign to be aware of is low fuel efficiency. As previously stated, by reusing the blow-by gases, you are saving the amount of fuel that needs to be used in the combustion process. The slower you use up the gasoline in your Mini, the less frequent your trips to the gas station become. You will know that there is an efficiency issue when you seem to be at the gas station more times than you have in the past.

One last sign to know about is engine misfire while idle. To function properly, the PCV system requires a certain amount of vacuum. When there is a loss of vacuum, misfires during idling will occur. The loss in vacuum is mainly due to a faulty PCV hose. The PCV hose could leak, be clogged, or pinched. In any of these cases, the PCV hose needs to be replaced.
