What does a clogged PCV valve do?
If the PCV valve is clogged the pressure in your crankcase will increase. This increase in pressure can cause your engine to misfire, run lean, or even stall, as well as potentially damage your engine.
If you notice these symptoms on your vehicle, it’s best to have your engine serviced to diagnose and fix the problem. When a clogged PCV valve develops, a vacuum may form in the system. When this happens, air will start to enter the system through the intake air hose. This air will be drawn into the compressor and cause the compressor to work harder than normal.
Over time, this can damage the compressor.
What is a clogged PCV valve on a car?
The car’s “ crankcase is the engine’s primary oil reservoir. A car’s oil is circulated through the engine as it runs, and the system is sealed with a PCV valve to prevent air from entering the system. The PCV valve is located on the underside of the car, usually near the oil fill tube.
The purpose of the PCV valve is to prevent air from entering the engine while it runs. A clogged PCV valve is a serious problem because it can cause engine overheating. If the clog is severe enough, it can cause your engine to not start at all or to misfire.
It could also cause your car to lose power. You could also end up with a burnt air conditioner compressor. If you suspect your car has a clogged PCV valve, don’t try to fix it on your own.

What does a clogged PCV valve mean?
A clogged PCV valve doesn’t cause any damage to your vehicle. It is simply a warning sign that something is going wrong if you notice it, because it could indicate a bigger problem that could have serious repercussions for your engine. A clogged PCV valve will cause your car to run hotter and use more fuel than necessary.
The PCV valve is the pipe that connects your car's cooling system to your radiator. The purpose of this pipe is to return the system's condensed water and any other debris that it encounters back to the engine. When the system is working properly, the PCV valve is able to prevent debris from building up in the engine.
When this valve is clogged, water or air may be forced through the engine, which is highly damaging to the engine's coolant system, as well as the engine
What does a clogged PCV valve do on a car?
If the rubber PCV valve is clogged and not working properly, it can affect engine performance. The system is part of the engine’s cooling system and helps to prevent engine overheating. The fluid, called a “PCV” (positive crankcase ventilation), flows through the system and absorbs any excess gas, which can damage the engine.
Without a working PCV valve, the pressure in the crankcase builds up. Eventually, pressure can build to unsafe levels and cause damage You won’t be able to smell anything odd when your car’s engine is running, but the underside of the car will be hot and will be covered in a greyish-white smoke.
The smoke is actually sooty dust that has been dislodged from inside the engine and now needs to be cleaned away. If the clogged PCV valve is not fixed in a timely manner, you may end up with a burnt engine.
What happens if your PCV valve is clogged?
If your PCV system is clogged, it will be unable to properly remove the majority of the moisture that builds up in your engine. This moisture will end up being ingested into your engine and cause damage. In addition, if the moisture is not properly removed, it can end up in the wrong areas of the engine and cause other issues. When sealed in the engine, the vacuum created by the crankcase’s oil pressure helps draw air, moisture, and pollutant-laden fumes from the engine. If your PCV valve is clogged, then the vacuum created by the oil pressure drops, allowing air to enter the crankcase, which can lead to corrosion, oil leaks, and compromised lubrication. It’s best to have your PCV valve regularly cleaned and inspected by a professional to prevent these problems.
