Dorman 615-380 OE FIX Intake Manifold with Gaskets for Buick Encore and Chevrolet Cruze/Sonic/Tracker/Trax

Overview

The Dorman 615-380 OE FIX intake manifold is designed to address a common failure mode in select Buick and Chevrolet engines. When the internal PCV valve becomes dislodged, oil can find its way into the intake, potentially impacting how the engine breathes and responds. This redesigned unit offers a more reliable airflow and fuel path, helping you keep the engine running as intended.

What sets this manifold apart is a redesigned retaining pin for the PCV valve, which helps prevent the valve from moving out of place over time. Paired with a complete installation kit, it provides the right seals and hardware so you can start the job with confidence.

Complete kit for a clean, efficient install

• New throttle body gasket
• Port gaskets
• Fuel injector O-rings
• MAP sensor O-ring
• Screws for mounting

The unit is built in the United States from a tough nylon polymer that resists cracking and warping under engine heat. This durable construction supports a stable air flow path and long-term reliability, even in demanding conditions.

In practice, related wear on the valve cover PCV diaphragm can occur. If signs of wear appear, a valve cover replacement may be considered alongside the manifold replacement by a professional or a confident DIYer.

Fitment is vehicle-specific. To confirm compatibility for your model, enter your vehicle trim in the garage tool and check the Confirmed Fit bar at the top of the product page. If you see an “i” in a blue circle, hover to view additional notes that explain compatibility for your exact configuration.

Real-world use cases include restoring proper air and fuel routing in affected Buick Encore and Chevrolet models, potentially reducing excessive oil consumption symptoms, and providing a complete, ready-to-install kit for a smoother repair process. While outcomes can vary, the OE FIX aims to offer a durable, factory-like alternative to the original equipment manifold.
