⚠️ Common Signs of Failure

• Oil leakage at the joint or fitting
• Incorrect or unstable level indication
• Restricted flow or oil backup
• Cracking, chafe or heat damage
• Abnormal oil pressure, smoke or component wear

🛠️ Service Notes

• Renew the sealing washers, O-rings or gaskets at each end rather than reusing them, and check the union faces are clean and unmarked
• Fit the line without pulling it into place; a return line that has to be strained to line up will crack or chafe through in service
• Keep the original routing, clips and protective sleeving so the line stays clear of hot and moving parts and cannot rub
• Do not kink a line, and do not straighten and re-bend a formed metal one — cap the open ends while the system is apart so no dirt gets in
• Tighten the unions to the figures given in the workshop manual for your engine, then run up and check both ends for weeps before closing the access
