Where is the PCV valve located in the engine?

[DawsonLynn]

It is generally installed on the valve cover (or nearby) or connected to the intake pipe. The PCV valve is a component of the crankcase forced ventilation system, which is often referred to as the "PCV system" or "exhaust gas recirculation system." Here is some additional information about the PCV valve: 1. Workflow: The crankcase mixture passes through the cylinder head cover, PCV valve, and crankcase gas hose into the intake pipe, and finally enters the combustion chamber via the intake valve for combustion. 2. Structure: It is mainly composed of the body, valve, valve cover, or spring, among other small components. Disassembly or breakdown maintenance is not recommended (during repairs). It can be disassembled or decomposed separately. 3. Common faults: Blockage or sticking; poor control, excessive or insufficient opening, which can affect working conditions and environmental emissions.
