If you are like most people, you probably don’t even think about your vehicle’s Positive Crankcase Ventilation (PCV) valve or aren’t aware your engine has one until it breaks. You can help extend the life of your engine by learning to identify the early warning signs you may have a PCV valve issue, and by making PCV valve maintenance a part of your routine vehicle care.
Signs You May Need to Replace Your PCV Valve
A PCV valve is critical for regulating the flow of gases through your vehicle’s PCV system, and when it isn’t functioning properly, you may notice a wide range of engine problems. Typical issues you may notice when your PCV valve has completely failed include:
- Oil leaks in the engine
- Buildup of sludge in the engine
- Increased internal engine pressure
- Engine surges
- Possible black smoke
Common problems when your PCV valve has become stuck include:
- The need to add oil more often
- Frequent engine misfires while idling
- Hard engine starts
Make Checking the PCV Valve Part of Your Routine Maintenance Program
While most manufacturers don’t set strict guidelines for how often you should replace your PCV valve, there is no reason to wait for an issue before replacing it. Keep your PCV valve working well by asking your mechanic to inspect it every time you bring your vehicle in for a tune-up.
Checking a PCV valve only takes a few extra minutes. The mechanics at J&S Diesel are experts when it comes to fixing any diesel vehicle from OTRs to mobile homes.
