Engine Valve Cover for Buick Encore, Cadillac ELR, Chevy Cruze, Sonic, Trax & Volt

Engine Valve Cover for Selected Buick, Cadillac, and Chevrolet Applications

Replacement engine valve cover for the exact model-year applications listed below. The supplied information includes comparison numbers for the valve cover, valve-cover gasket, and bolt applications.

Critical fitment warning: Valve covers can vary by engine displacement, engine code, production date, turbocharger configuration, hybrid powertrain, emissions package, crankcase-ventilation design, ignition-coil layout, hose and sensor connections, and gasket profile. The source does not provide engine size or code. Confirm the VIN, exact engine and powertrain, production date, original cover shape, PCV layout, port locations, mounting pattern, gasket channel, and every reference number before ordering.

• 2011–2015 Chevrolet Volt

Not confirmed: Every engine offered within these ranges, specific turbocharged or naturally aspirated applications, gasoline-only versus hybrid interchange, engine-code interchange, market-specific variants, unlisted years or models, or any engine whose cover, PCV system, ports, gasket channel, coil layout, or mounting pattern differs.

Product Specifications

• Product type: Engine valve cover
• Location: Top of engine / cylinder head
• Source-listed makes: Buick, Cadillac, Chevrolet

The source does not state the cover material, color, engine displacement, engine code, exact PCV construction, sensor provisions, oil-fill-cap inclusion, port sizes, or production-date splits. Do not infer these specifications from the SKU or broad vehicle ranges.

Package Contents

• Engine valve cover component or kit; exact included contents and quantity not specified

The source provides comparison numbers for a valve cover, gasket, and bolt, but it does not explicitly itemize the package contents. A valve-cover gasket, spark-plug-tube seals, bolt grommets, mounting bolts, oil filler cap, PCV valve or diaphragm, breather fittings, hoses, clamps, sensors, sealant, and tools are therefore not confirmed as included. Verify the product images and received package before disassembly.

Reference Numbers

Valve cover: 25198498, 25198874, 25198877, 25203036, 55573746, 264-968

Valve-cover gasket: 25198753, 55573747

Bolt: 11547061

These numbers are supplied for comparison and application checking. They do not prove that every referenced gasket or bolt is included, and a matching number does not override engine-code, hybrid, turbocharger, PCV, port-layout, or production-date differences.

When to Inspect the Original Cover

Possible signs of a valve-cover or sealing-system problem include visible oil leakage around the cover, oil collecting near ignition components, a burning-oil odor, smoke caused by oil contacting hot surfaces, crankcase-ventilation faults, or rough operation. These symptoms can also result from other engine, ignition, sealing, or ventilation problems. Diagnose the vehicle before replacing parts.

Installation Notes

Professional installation is recommended. Work only on a cool engine and follow the VIN-, engine-, turbo-, and hybrid-specific service procedure. Observe all high-voltage safety requirements for Cadillac ELR and Chevrolet Volt applications; only qualified personnel should service components near a hybrid high-voltage system.

Before installation, compare the replacement with the original cover for overall shape, bolt pattern, gasket channel, oil-fill opening, coil openings, PCV and breather ports, hose connections, sensor provisions, and mounting heights. Do not install a cover with different ventilation routing, missing ports, or mismatched sealing surfaces.

Clean the cylinder-head sealing surface without scratching it or allowing debris to enter the engine. Remove old gasket material and oil from the sealing area. Use only the gasket, sealant locations, tightening sequence, and torque values specified for the exact engine. Excess sealant can enter oil passages, while overtightening can crack or distort the cover and create leaks.

Inspect hoses, fittings, ignition components, fasteners, and sealing surfaces during service. After installation, start the engine and inspect for oil or vacuum leaks, warning lights, abnormal noise, and correct crankcase-ventilation operation. Recheck the sealing perimeter after the engine reaches operating temperature and after an initial drive.

Frequently Asked Questions

Is the valve-cover gasket included?
The source supplies gasket reference numbers but does not explicitly list a gasket as packaged. Confirm the product images and received contents.

Are mounting bolts included?
Bolt reference 11547061 is provided, but bolt inclusion and quantity are not confirmed.

Which engine does this fit?
The source lists models and years but no engine displacement or code. Confirm the VIN, engine code, turbo or hybrid configuration, PCV layout, and original cover.

Does this fit Cadillac ELR and Chevrolet Volt hybrid applications?
The source lists 2014–2016 ELR and 2011–2015 Volt. Verify the VIN, exact powertrain, original cover, ports, and reference numbers, and follow hybrid high-voltage safety procedures.

Does the cover include PCV components?
PCV valve or diaphragm inclusion is not confirmed. Compare the ventilation design with the original cover before ordering.
