What is a PCV valve on a truck?
“PCV” stands for “positive crankcase ventilation.” It is a one-way valve attached to the crankcase. Your vehicle’s crankcase holds your motor oil, and is located at the bottom of your engine. This can lead to the gases mixing with motor oil to create corrosive, engine-clogging sludge.

How does the PCV valve in a car work?
The PCV valve works by recirculating blow-by gases in the crankcase back to the intake manifold. Positive crankcase ventilation boosts efficiency while reducing emissions because the recirculated fumes are able to be combusted again, leading to more efficient fuel use.
Where can I get a replacement PCV valve?
