⚙️ Key Features

• Supersedes 840955
• 0.102 kg
• Lubricating and Oil System group

🔌 Function

Returns oil from the turbocharger back to the cylinder block by gravity, keeping the bearing housing drained.

⚠️ Common Signs of Failure

• Oil weeping or dripping at either end of the pipe
• Blue smoke and oil showing in the inlet pipework, which a restricted return will cause
• Pipe cracked, chafed or crushed along its run
• Pipe partly blocked with carbon or sludge on removal
• Turbo bearing seals leaking repeatedly despite the turbo having been overhauled

🛠️ Service Notes

• Check that the pipe is clear before refitting - a restricted or kinked oil return will push oil past the turbo seals and can destroy a new turbocharger
• Renew the sealing rings at both ends; a return line has to be air-tight as well as oil-tight
• Turbocharger 860352 is the turbo listed in this run
