Would you be able to tell if your Mini is due for PCV valve replacement? If not, then continue reading. Positive Crankcase Ventilation, which is known as PCV is a very important part of your car’s emission control system. It controls the gas flow from the crankcase to the intake manifold, where they are burnt in the combustion process. This component prevents harmful emissions from entering the atmosphere and guarantees maximum engine performance. Let’s discuss some of the symptoms of a bad valve and the process of changing it.
How To Know Your PCV Valve Is Due For Replacement
- Rough Idle: A rough or shaky idle that results in the engine RPM jumping or the car vibrating excessively while idling, among other symptoms, can be a sign of PCV valve problems. When the PCV fails to do its work, the air-fuel ratio in the engine would be disrupted which in turn would affect how your Mini idles.
- Check Engine Light: The onboard diagnostic system may trigger the check light on your Mini’s dashboard if it detects malfunctions in the PCV valve or in its related system. It is important to have the vehicle diagnosed immediately to know the exact cause of the problem.
- Smoke from the Exhaust: A faulty PCV valve can also allow excessive oil vapor to enter the combustion chamber, which will then be burnt in the cylinders and released in the exhaust either as blue or gray smoke. Whenever you see this kind of smoke, it means there’s likely a problem with the PCV and you must attend to it immediately to prevent damage in other parts of your Mini.
Replacing The PCV Valve
- Locate the PCV Valve: PCV valve is generally found on the valve cover or engine block. Although the location can be different depending on the model of your Mini. To locate this component, check your owner’s manual or let your car technician locate the valve.
- Remove the Old Valve: When you have finally gotten to the PCV valve, the next thing to do is to disconnect it from the hose or mounting bracket. At this point, you have to be very careful so you do not damage the valve or other components around it. Before removing the valve, check to see if there are any signs of wear, damage, or accumulated dirt.
- Install the New Valve: Installation is an integral part of the replacement process and it should be done in the right manner to avoid leaking or malfunctioning. When replacing the valve, you have to connect it to the hose or mounting bracket, almost the same way you pulled it off. Make sure that the valve is tightly fastened and that it is seated properly so that there is a tight seal.
- Test the Replacement: Drive your Mini and see if the car’s performance has improved after fitting the new PCV valve. Carry out the necessary checks so you’ll be sure if there are any signs of improvement, such as the engine operating smoothly or reduced oil consumption. Continue to monitor your car’s performance for a few days to be sure the problem has been fixed.
- Professional Inspection: PCV valve replacement should not be done by anyone who is not an expert. If you have tried replacing the PCV valve by yourself and still have a problem with it after the replacement, it is better to consult a professional mechanic. A professional will make sure that the diagnosis of any underlying problems is done right and that the replacement of the PCV valve is properly done.
