⚙️ Key Features

• Oil return line

• Covers its five applications across D and MD series engines
• Within 7 grams of return line 23072578

🔌 Function

Drains oil back to the sump under gravity after it has done its work, keeping the return path clear so oil does not back up where it was fed.

⚠️ Common Signs of Failure

• Oil weeping or dripping at a union on the return run
• Blue smoke and oil in the charge pipework where a turbocharger return is restricted
• Oil pushing past a seal because the drain cannot clear
• Line found kinked, crushed or coked up internally
• Union faces scored or the flare cracked on removal

🛠️ Service Notes

• Prove the return line is clear before condemning a seal or a turbocharger - a restricted drain forces oil past seals that are otherwise sound
• Renew the sealing washers at each union and keep the run falling continuously to the sump
• Order by part number - 23072578 is within a few grams and covers a different engine list
