Dorman 264-968 Engine Valve Cover Compatible with Select

In this review the Dorman 264-968 engine valve cover is evaluated for drivers who need a straightforward replacement for worn or damaged valve covers on select Buick, Cadillac and Chevrolet models. The bottom line: it is a practical, complete repair option because it matches original fit and function, is molded from heat-resistant polymer, and arrives with a new gasket and bolts to simplify installation. For someone replacing a leaking cover or restoring a damaged PCV diaphragm, this part usually restores function without the hassle of sourcing multiple components.

Key Features

• Direct replacement: Injection molded polymer construction provides a fit and shape that aligns with the original equipment for reliable sealing.
• Complete solution: The kit includes a new gasket and bolts so a single purchase covers the common parts needed for the repair.
• Heat resistance: The polymer material resists engine bay heat and helps maintain sealing performance over time.
• Quality tested: Try-on and material testing were performed to confirm fit and reduce the risk of early failure.
• Repair guidance: The listing notes that related intake manifold failures and missing PCV valves can affect function, helping buyers plan a fuller repair if needed.

Who It's For

This valve cover is best for DIY mechanics and independent shops working on compatible Buick Encore, Cadillac ELR, Chevrolet Cruze, Sonic, Trax, Tracker and Volt model years listed in the product description who want a like-for-like replacement without hunting for separate gaskets and hardware. It suits owners fixing oil leaks, replacing a failed PCV diaphragm, or refreshing a tired engine top-end for confidence in sealing.

Drivers with vehicles outside the listed model years or who require OEM-branded warranty coverage should verify fitment closely with the garage tool before buying and may prefer to source dealer parts. Also, if the intake manifold or PCV valve is known to be faulty, those items should be addressed in addition to this cover for a durable repair.

Pros & Cons

Pros

• Quality fit and function due to injection molded polymer that mirrors the original part.
• Comes with a new gasket and bolts, reducing the parts you must buy separately.
• Tested for material and fit, which lowers the likelihood of early fitment issues.
• Restores PCV diaphragm performance when that is the source of reduced function.

Cons

• Some customers report oil leakage through bolt areas or missing bolts in rare cases, so inspect the hardware on arrival and follow the correct bolt tightening sequence.
