Dorman Engine Valve Cover 264-968 for GM 4-Cylinder — Injection-Molded Polymer with Gasket & Bolts

The Dorman 264-968 Engine Valve Cover is an injection-molded polymer direct replacement that restores sealing, heat resistance, and PCV diaphragm function for compatible GM 4-cylinder engines.

This valve cover is designed to match the fit and function of the original equipment part while providing durable heat resistance and a full repair kit. It arrives with a new gasket and mounting bolts so you can replace a worn or cracked cover and reseal the top of the engine in a single job. Dorman tests fit and material to help ensure consistent installation and long-term service.

Which vehicles is this valve cover compatible with?

The Dorman 264-968 fits a range of GM compact and subcompact models across multiple years. Compatibility includes Buick Encore, Cadillac ELR, Chevrolet Cruze (and Cruze Limited), Sonic, Tracker, Trax, and Volt model years listed by Dorman. Always confirm your exact make, model, and trim in the fitment/garage tool before ordering to avoid returns.

• Buick Encore: 2013–2021
• Cadillac ELR: 2014–2016
• Chevrolet: Cruze (2011–2016), Cruze Limited (2016), Sonic (2012–2020), Tracker (2013–2015), Trax (2013–2021), Volt (2011–2015)

What materials and construction does this cover use?

This valve cover is made from injection-molded polymer chosen for dimensional stability and heat resistance under engine bay temperatures. The polymer construction helps reproduce the original mounting points and sealing surfaces so the new cover mates correctly with the cylinder head.

• Injection-molded polymer construction for consistent fit
• Engineered sealing surfaces to match OEM geometry
• Tested for material durability and try-on fit verification

Does the part include everything needed for installation?

Yes — Dorman supplies the valve cover with a new gasket and the required bolts, so you get a complete repair package. That reduces the chance of leaks caused by reusing old hardware or a compressed gasket and simplifies a do-it-yourself or shop replacement.

• New cover plus pre-formed gasket for reliable sealing
• Included bolts sized to the application for correct torque
• Ready for immediate installation after prep and surface cleaning

When should I consider replacing related engine parts?

Valve covers often leak or fail in vehicles where the PCV diaphragm or the intake manifold has issues; Dorman recommends inspecting related components during replacement. If the intake manifold or PCV valve is missing or damaged, replace those parts to prevent repeat failures and ensure correct crankcase ventilation.

• Inspect PCV diaphragm and replace if torn or collapsed
• Check intake manifold integrity if manifold-mounted PCV is used
• Clean sealing surfaces and replace gasket to avoid oil leaks

Who is this product for: This valve cover is intended for vehicle owners, independent mechanics, and repair shops working on compatible Buick, Cadillac, and Chevrolet models that require a like-for-like replacement. It suits drivers who need a reliable sealing solution and prefer a complete kit — cover, gasket, and bolts — to minimize parts sourcing and downtime. For accurate fitment, enter your vehicle details into the fitment tool before purchase to confirm compatibility.
