Keep your Subaru's engine sludge free and protect important seals by getting your PCV valve changed every 60k miles!
A functioning PCV valve protects Subaru engines from oil leaks and fuel contamination. It helps manage blow-by gases(unburned combustion by-products) that slip past piston rings and cause sludge and carbon buildup. It also protects against sudden pressure spikes that can damage critical engine seals.
