MILIPARTS Engine Valve Cover for Chevy Cruze Sonic Trax Aveo 1.6L/1.8L – Direct-Fit, OEM-Style Seal

MILIPARTS Engine Valve Cover is a direct-fit replacement engineered to restore a secure seal and OEM-level durability for select 1.6L and 1.8L GM engines.

When an original valve cover shows oil seepage, cracks, or worn mounting points, replacing it with a precision component stops leaks and protects internal engine components. This MILIPARTS valve cover is designed specifically to fit a range of GM models including Chevy Cruze (2010–2016), Aveo/Aveo5 (2009–2011), Sonic (2012–2018), Trax (2013–2020), and compatible Astra/Pontiac/Saturn variants. Built to match OE dimensions and reference numbers, it offers a practical, cost-effective path to repair without modifying the cylinder head or associated hardware.

How does this cover improve engine reliability?

A properly sealing valve cover prevents oil leaks, keeps contaminants out of the valve train, and ensures proper ventilation when combined with the PCV system. Using a high-quality replacement like this reduces the likelihood of gasket failures and oil pooling on top of the engine, which can lead to smoke or unpleasant odors.

• Manufactured to meet or exceed OEM standards for material and fit
• Precision sealing surfaces minimize the need for additional modifications
• Durable construction resists warping and cracking under heat cycles
• Maintains correct PCV and breather port alignment with stock components

What should I know about installation and compatibility checks?

Installation is straightforward for DIYers with basic tools and mechanical knowledge, but verify the mating surfaces, bolts, and any sensors or grommets before final torqueing. Replace the valve cover gasket and any worn fasteners or grommets during the job to ensure a lasting repair.

• Inspect and replace the valve cover gasket, bolts, and grommets when installing
• Clean mating surfaces on the cylinder head for a proper seal
• Torque bolts to factory specifications in the recommended sequence
• Confirm PCV valve and hose alignment to avoid misrouting or leaks

Which OE part numbers does this replace and why does that matter?

This MILIPARTS cover replaces OE reference numbers 55564395 and 96889998, meaning it matches the original geometry and mounting pattern used by the manufacturer. Sourcing a cover that cites those part numbers simplifies fit confirmation and reduces the risk of purchasing an incompatible aftermarket item.

• Direct OE replacements streamline parts matching and installation
• References help verify compatibility across model years and trims
• Using a cover specified for your OE number reduces modification needs
• Supports resale value by maintaining factory-equivalent components

Who is this for: This MILIPARTS valve cover is for vehicle owners, independent mechanics, and repair shops working on GM small-displacement engines (1.6L/1.8L) who need a reliable, direct-fit replacement. If your car exhibits oil seepage around the valve cover, you want an OEM-dimensioned replacement, or you're performing routine engine maintenance and want parts that match factory specs, this part is suitable. Always cross-check the listed part numbers and your vehicle’s engine code to ensure a correct fit before purchase.
