GM 1.4L Ecotec (Cruze/Sonic/Trax) Remanufactured Cylinder Head
Professional Solution for LUV/LUJ Turbo Engines – Precision Surfaced & Pressure Tested
Restore your engine’s peak volumetric efficiency and thermal management with this professionally remanufactured cylinder head, specifically engineered for the GM 1.4L DOHC Ecotec Turbo series. Designed to address the common thermal fatigue and cracking issues inherent to this platform, each unit undergoes a rigorous multi-stage remanufacturing protocol—including ultrasonic cleaning, precision deck resurfacing, and high-pressure leak testing—to guarantee a superior head gasket seal and optimal combustion chamber integrity.
Utilizing high-grade aluminum alloy, this cylinder head is precision-machined to meet or exceed original equipment (OE) dimensional tolerances, ensuring a direct-fit solution for your turbocharged induction system. Our remanufacturing process focuses on critical stress points within the casting to prevent future overheating and coolant loss, restoring the factory-spec compression required for peak fuel economy and throttle response. Whether you are performing a top-end overhaul on a Chevrolet Cruze, Sonic, or Buick Encore, this Ecotec head provides the structural durability and cooling capacity necessary to regain long-term engine reliability.
🛠️ In-House Machining Process
- Cleaning: Fully disassembled and chemically cleaned to bare metal.
- Soda Blasted: Castings are blasted with Sodium Bicarbonate. Because baking soda is water-soluble, there is zero risk of abrasive media clogging the small oil passages of the Ecotec platform.
- Pressure Testing: Multi-stage tested to 60 PSI to guarantee no porosity or hairline cracks—the #1 failure point on these turbo heads.
- Surfacing: All heads are resurfaced on our Rottler S85A to ensure a perfect head gasket seal.
- Valve Job: Multi-angle valve seat grind and high-temp Viton valve seals to stop oil consumption and maximize vacuum.
