Replace a leaking, damaged, or corroded factory turbo oil return line on your 2011–2016 GM 6.6L Duramax with the Dorman Turbo Oil Return Line. Designed as a direct-fit, OE-style replacement, this vehicle-specific line connects the factory turbocharger oil passage to the engine and helps restore proper oil return function.

The original turbo oil return tube can deteriorate over time due to corrosion and exposure to harsh underhood conditions. Dorman addresses this with durable steel construction and a nickel-coated finish designed to provide increased corrosion resistance and dependable service life.

Engineered specifically for use with the factory turbocharger, the line features factory-style flanged connections for straightforward installation. Gaskets and mounting hardware are included, providing the components needed to replace the original return line and help prevent oil leaks.
