One component that is sometimes overlooked but plays a crucial role in the performance of your Land Rover is the PCV valve. This valve may wear out or get blocked and this leads to problems with the engine. Changing the PCV valve is not a complicated process and once done properly will help your engine to continue to run efficiently. Let’s see how to change the PCV valve of a Land Rover in a few easy steps.
What PCV Valves Do
The PCV valve is one of the smallest components of your car’s engine. The major function of this small part is to control the movement of gasses produced in the crankcase and return them back to the combustion chamber. This process plays a role in ensuring that your engine does not accumulate a lot of dirt while it is in use. The PCV valve can become blocked or fail after some point and this can lead to problems in the engine.
Signs That You Need To Replace Your PCV Valve
There are some signs that can indicate that the PCV valve is failing. One of the symptoms you may notice in your Land Rover is a rough running engine or stalling due to the disruption of the air-fuel mixture by an ineffective PCV valve. Another sign is that fuel economy drops drastically as the engine is no longer able to run smoothly.
You may also have a check engine light on the dashboard, which is often a result of trouble codes that are linked to the PCV system. Last but not least, a deposit of a black or bluish color on your tailpipe may be an indication that the engine is burning oil because of inadequate ventilation.
A Guide on How to Change the PCV Valve
- Remove Old PCV Valve: The first step you should take is to open the hood of your Land Rover. The PCV valve is usually mounted to a hose that goes from the crankcase to the intake manifold. If you cannot locate it, then you should look at the owner’s manual of your car for assistance. Slowly disconnect the hose that is connected to the PCV valve. If the hose is stuck, use a pair of pliers to try and help get the hose free. After the hose is disconnected, the PCV valve needs to be unscrewed from its place. It is also necessary to have a clean piece of rag to clean any oil or debris around the valve area.
- Install the New PCV Valve: After removing the valve, look at the hoses that are connected to it for a moment. Check for any signs of wear, crack lines, and clogs. In case you find any hose damaged, it is advisable to replace them with a new one to have a proper functioning system and avoid other problems. Screw in the new PCV valve until it is hand-tight. Once it is hand-tight, you should then tighten it further using a socket set or a wrench. Ensure that you do not over-tighten the valve since this may lead to either the valve or the threads being damaged.
- Reconnect Hose and Double-Check Everything: Reconnect the hose back into the new PCV valve. Make sure it is tight and well-fixed. If earlier the hose was hard to remove then it would be better to replace it with a new one to prevent any kind of issues in the future. After the new PCV valve is installed, and the hose is connected back, ensure that all the connections are well tightened. Thoroughly clean the area around the valve and remove any form of dirt or oil that is around it.
