Genuine Hyundai/Kia 28240-2G401 Brake Vacuum Tube
Product Description
The Genuine BMW 11427844986 is an OEM Turbocharger Oil Return Line, also referred to as a drain line or oil outlet tube. This critical component is responsible for safely draining engine oil from the turbocharger's central cartridge back to the oil pan after lubrication. A functioning return line is essential to prevent oil from backing up into the turbo, which can cause seal failure, excessive smoke, and catastrophic turbocharger damage. This specific part is for the right-side (passenger side) turbocharger on Bank 1 of BMW's high-performance V8 engines.
Choosing this genuine BMW part guarantees a perfect fit, material compatibility, and reliability that meets the stringent requirements of forced-induction engines, ensuring your vehicle maintains optimal performance and longevity.

Installation & Symptoms of Failure
Common Symptoms of a Failing Oil Return Line:
Excessive Blue/White Smoke from Exhaust: Oil leaking into the exhaust housing or downstream due to poor drainage.
Oil Leaks Around Turbocharger: Visible oil seepage or drips from the lower connection of the turbocharger.
Burnt Oil Smell: Oil dripping onto hot exhaust components.
Turbocharger Failure: Whining noises or loss of boost pressure caused by bearing damage from oil starvation or contamination.
Installation Advisory:
Replacement of this line requires accessing the turbocharger assembly. It is recommended to replace the associated seals and gaskets (such as O-ring 11 42 7 578 079 and gasket 11 42 8 624 158) for a leak-free repair. Due to the complexity and need for proper torque specifications, professional installation by a qualified technician is strongly recommended.
Frequently Asked Questions
Q: Is this the oil feed line or the oil return line?
A: This is the oil RETURN line (drain line). It carries oil away from the turbocharger back to the oil pan. The oil feed line, which supplies pressurized oil to the turbo, is a different, usually smaller-diameter part.
Q: Why choose a genuine BMW part over an aftermarket alternative?
A: Genuine BMW parts are precision-engineered to withstand the exact heat cycles, vibration, and fluid pressures of your specific engine. A failure in this critical component can lead to very expensive turbocharger or engine damage, making OEM reliability a crucial investment.
Q: Does this part fit both the left and right turbochargers?
A: No. Part number 11427844986 is specifically for the right-side (passenger side) turbocharger on Bank 1. The left-side (driver side) turbo requires a separate, different part number.
