Dorman Intake Manifold and Valve Cover Complete Repair Kit for GM 1.4L Ecotec – 615-380KIT, Improved PCV Support

The Dorman Improved Design 615-380KIT is a complete intake manifold, valve cover, and PCV tube repair kit engineered to replace failed components on GM 1.4L Ecotec engines and reduce recurring PCV valve failures.

If your Buick Encore, Chevrolet Cruze, Sonic, or Trax with the 1.4L Ecotec engine is showing rough idle, oil consumption, vacuum-related fault codes, or other symptoms tied to a failing PCV system, this Dorman OE FIX kit provides a one-purchase solution. Instead of replacing only the broken valve, this package replaces the intake manifold, valve cover, and PCV tube with an improved intake design that addresses a known weakness in the original equipment.

How does the kit stop repeated PCV valve failures?

Dorman redesigned the intake manifold to address the failure mode commonly seen on GM 1.4L Ecotec engines. The updated geometry and reinforced PCV mounting reduce stress and the chance of valve breakage, preventing the same component from failing again after repair.

• Redesigned intake manifold for improved PCV support
• Stronger PCV tube attachment to prevent cracking during service
• Complete replacement of interconnected parts to avoid repeat failures

What comes in the 615-380KIT and why is a full kit better?

The kit contains a replacement intake manifold, valve cover, and PCV tube assembly so you don’t have to track down individual parts. Replacing all three items at once eliminates worn mating surfaces and hidden damage that can cause new or recurring issues after a partial repair.

• Intake manifold with improved PCV valve interface
• Valve cover compatible with the manifold and updated tube routing
• PCV tube assembly designed for easier, more secure installation

Which vehicle models and years are compatible with this kit?

This kit fits a range of Buick and Chevrolet models equipped with the GM 1.4L Ecotec engine. Always verify fitment by checking your vehicle trim in the garage tool or comparing OEM part numbers before purchase.

• Buick Encore: 2013–2019
• Chevrolet Cruze: 2012–2015 (and Cruze Limited 2016)
• Chevrolet Sonic: 2012–2018
• Chevrolet Trax: 2013–2019

What problems can be resolved after installing this kit?

Replacing the intake manifold, valve cover, and PCV tube commonly resolves symptoms caused by PCV system failure. While individual results vary, many owners report reduced oil consumption, fewer vacuum-related engine codes, and smoother idle after installing the full kit.

• Reduces excessive oil consumption linked to PCV failure
• Helps restore correct vacuum pressure and engine idle stability
• Prevents repeated PCV valve breakage and related fault codes

Who is this for: This Dorman OE FIX 615-380KIT is designed for DIY mechanics and professional shops repairing GM 1.4L Ecotec engines that have experienced PCV valve or related intake/valve cover failures. It’s especially useful when the original parts have broken or when previous partial repairs failed—offering a comprehensive replacement that targets the root cause rather than just the symptom.
