Dorman 667-428 Turbocharger Oil Return Line

The Dorman 667-428 is a direct-fit turbocharger oil return line (also known as a turbo oil drain line or oil outlet tube) designed to replace the original equipment line on select turbocharged vehicles. This line routes used oil from the turbocharger bearing housing back to the engine oil pan, ensuring proper lubrication drainage and preventing oil leaks or pressure buildup within the turbo assembly.

Key Features:

• Direct OE replacement — engineered to match original equipment fitment, routing, and connection points
• Designed to restore proper turbocharger oil drainage and prevent oil starvation or seal failure
• Constructed to withstand high operating temperatures associated with turbocharged applications
• Includes all necessary hardware and seals for a complete installation
• Manufactured by Dorman Products, a trusted name in OE-quality replacement parts

A failed or leaking turbocharger oil return line can cause oil to pool in the turbo housing, leading to blue smoke, oil burning, or premature turbocharger failure. Replacing a damaged or deteriorated return line with the Dorman 667-428 helps restore reliable turbo performance and protects your engine investment.
