• Description:

  This Genuine Ford ML3Z-6K775-A is the turbocharger oil drain line for 21-25 F-150 applications equipped with the 3.5L EcoBoost twin-turbocharged engine. The molded steel line carries the pressurized engine oil that lubricates and cools the turbocharger bearing cartridge back to the oil pan, allowing the turbo to maintain proper bearing oil flow under both vacuum and pressurized intake conditions across the full operating range. The integrated O-ring sealing flanges at both ends seat against the turbo center housing and the oil pan return port. Owners replace this line when an oil leak at the turbocharger or oil pan return point traces to a hardened or torn end-seal O-ring, when the line itself has cracked from underhood vibration and heat-cycle fatigue, when a previous repair has bent the line during R&R of adjacent components, or during a complete turbocharger service that includes preventive replacement of the oil supply and return hardware. Installation requires the line to be carefully aligned with the turbocharger and oil pan ports so the O-ring seals seat without rolling, and the bolt-on flanges to be torqued in the Ford-specified pattern with new gasket hardware where applicable.
