Manage crankcase pressure and route blow-by vapors back to the intake with the Standard Ignition PCV Valve V597. This positive crankcase ventilation valve meters the flow of blow-by gases out of the crankcase and into the intake so they can be re-burned, while helping keep pressure balanced inside the engine. It drops in as a direct-fit replacement across a broad range of GM cars, crossovers, and trucks, including the 2016-2022 Buick Encore [L4-1.4L], 2013-2018 Cadillac ATS [L4-2.0L] and [L4-2.5L], 2016-2018 Chevrolet Camaro [L4-2.0L], 2018-2024 Chevrolet Equinox [L4-1.5L], and 2013-2024 Chevrolet Malibu — 31 applications in all; see the Buyer's Guide tab for the full list.
Manufacturer part number V597. If a failed PCV valve is the cause of a rough idle, oil leaks, or excess oil consumption, this replaces it — diagnose the cause before installing.
What does the PCV valve do?
It meters blow-by gases from the crankcase into the intake to be re-burned, helping keep crankcase pressure balanced. It does not stop blow-by itself, which comes from ring and cylinder wear.
Will this fit my vehicle?
It's a direct-fit replacement for 31 GM applications spanning the L4-1.4L, L4-1.5L, L4-2.0L, and L4-2.5L engines. Check the Buyer's Guide tab to confirm your exact year, model, and engine.
What are signs a PCV valve may need replacing?
A rough idle, whistling or hissing, oil leaks at gaskets and seals, or higher oil consumption can be signs. These symptoms have other causes, so diagnose before replacing.

It covers the L4-1.4L, L4-1.5L, L4-2.0L, and L4-2.5L engines used across the listed Buick, Cadillac, Chevrolet, and GMC applications.
Does it fit the Chevrolet Malibu?
Yes. It is listed for the 2013-2024 Chevrolet Malibu, plus the 2016 Malibu Limited [L4-2.5L]. Confirm your specific engine in the Buyer's Guide tab.
