What is the part number for the PCV bypass pipe on a 2012 Chevy Cruze?

The exact PCV bypass pipe part number for a 2012 Cruze depends on the engine configuration and VIN; there isn’t a single universal number. To get the correct part, you must identify the specific engine and lookup the part in the GM parts catalog or through a dealer using the VIN.

Why part numbers vary by configuration

GM uses different PCV plumbing depending on the engine setup and production year. In the 2012 Cruze line, two main configurations were common: a naturally aspirated 1.8-liter engine and a turbocharged 1.4-liter engine. Each configuration has its own PCV routing, seals, hoses, and accompanying pipe sections, which means the official replacement part numbers are not interchangeable between engines.

Common engine configurations for the 2012 Cruze

• 1.8-liter gasoline engine (non-turbo): This configuration uses a specific PCV pipe layout and associated gaskets and hoses tailored to that engine family.


• 1.4-liter turbocharged engine: This setup uses a different PCV bypass pipe assembly, which may include additional hoses or a different connector arrangement to match the turbocharged setup.

Because the part numbers are engine-specific, confirming the exact configuration is essential before ordering.

How to obtain the exact part number

To ensure you get the correct PCV bypass pipe for your Cruze, follow these steps to verify the right part number.

• Identify the engine code and trim, which may be found on the service sticker under the hood or by checking the vehicle’s window sticker or service records.


• Locate the vehicle’s VIN and use it in a GM Parts Catalog search or at a dealership parts counter to pull up the exact PCV bypass pipe for that VIN and engine configuration.


• Cross-check the part diagram for the PCV bypass pipe to confirm you’re selecting the same routing, connectors, and seals as the original.


• When in doubt, contact a GM dealership parts counter with the VIN and request the “PCV bypass pipe” assembly for the specific engine code and year.

Concluding: The precise number is tied to your engine code and VIN, not the year alone. Verifying through an official catalog ensures an exact match and proper fit.

Where to buy and how to verify

Reliable sources and verification steps help ensure you don’t order the wrong part. Start with official catalogs and then cross-check with retailers for pricing and availability.

• GM dealer parts department or the GM Parts Direct online catalog, using your VIN or engine code to locate the correct PCV bypass pipe.


• OEM cross-reference retailers (e.g., RockAuto, AutoZone) that list GM PCV pipe assemblies compatible with the 2012 Cruze by engine code or VIN.


• Always confirm fitment against the diagram and the vehicle’s specific engine configuration before purchasing.

Concluding: After confirming the exact part number, compare prices across reputable suppliers and review return policies in case the part doesn’t fit as expected.
