Sumyola Valve Cover Kit for Chevy Cruze Sonic Trax Aveo Pontiac G3 — Direct-Fit 1.6L/1.8L with Gaskets & Seals

Sumyola's complete valve cover kit replaces OEM 55564395/55558673 for 1.6L and 1.8L Chevy/GM engines, delivering a direct-fit, leak-tested solution with gaskets, bolts, and spark plug tube seals included.

When a worn valve cover or degraded spark plug tube seal causes oil seepage, this Sumyola assembly is built to restore a proper seal without hunting for extra parts. Designed to match the original dimensions and fastening points, the kit fits a range of GM compact models — Chevy Cruze, Sonic, Aveo/Aveo5, Trax, Pontiac G3, and compatible Astra variants — making it a practical repair for common 1.6L/1.8L engine service needs.

How does this valve cover kit solve oil leaks on older 1.8L engines?

The kit addresses the two most common leak sources: the valve cover gasket and the spark plug tube seals. Sumyola uses heat-resistant composite gaskets and individually pressure-tests each unit to confirm oil-tight performance before shipping. That reduces the chance of repeat labor to chase persistent seepage.

• Includes premium heat-resistant valve cover gasket and spark plug tube seals.
• Precision-machined sealing surfaces limit common leak paths around plug tubes.
• Each assembly undergoes standalone leak/pressure testing prior to shipment.

Will this fit my vehicle and require any modifications?

This product is engineered as a direct OEM-style replacement for specified GM part numbers and model years, so it installs without drilling or trimming. Sumyola also offers VIN-based fitment verification to ensure compatibility before you install. If the part does not match your vehicle, a refund is offered with no restocking fee.

• Direct fit for Chevy Cruze (2010–2016), Sonic (2012–2018), Trax (2013–2020), Aveo (2009–2011), Pontiac G3 (2009–2010).
• Replaces OEM numbers 55564395, 55558673, 96889998 for 1.6L/1.8L engines.
• VIN verification available and non-matching returns accepted without restocking fees.

What comes in the kit and what tools or parts will I still need?

Sumyola supplies a complete install package so you won’t need to source separate gaskets or seals. The box contains the valve cover, premium gaskets, spark plug tube seals, and the necessary mounting bolts. Typical installation requires basic hand tools and a torque wrench; new spark plugs and ignition components are optional depending on condition.

• Included: valve cover, heat-resistant gaskets, spark plug tube seals, bolts.
• Recommended tools: basic hand tools, torque wrench, gasket scraper, cleaner.
• Optional: inspect and replace spark plugs or ignition coils if serviceable items are worn.

How does Sumyola ensure quality and what warranty covers this part?

Manufactured in a certified 50,000 m² facility with over 16 years of OE-supply experience, the kit is produced from advanced composites for thermal stability and oil resistance. Each unit goes through individual leak testing, and Sumyola backs the product with a one-year warranty and in-house technical support. That combination helps reduce installation risk and gives recourse if defects appear.

• Made in a certified facility with OE-supply experience and quality controls.
• Advanced composite materials resist heat and oil degradation over time.
• One-year comprehensive warranty plus technical support and installation guidance.

Who is this for? If you own or service GM compact cars with the 1.6L or 1.8L engines listed and need a reliable, one-box valve cover replacement, this Sumyola kit is aimed at DIY mechanics, independent shops, and fleet technicians who want a direct-fit, leak-tested option. It’s particularly useful when spark plug tube seepage or aged gaskets are causing oil loss or fouled ignition components and you prefer a single purchase that includes seals, bolts, and support rather than sourcing multiple parts separately.
