Oil Return Line for EGTC OM904 Euro 4/5
Detroit Diesel

The oil return line for the OM904 Euro 4/5 engine is a rubber hose designed to efficiently channel used oil back to the sump after passing through the engine’s lubrication and filtration systems. Its inner diameter of 19.50 mm and outer diameter of 22 mm ensure a snug fit within the oil circuit, preventing leaks and maintaining consistent flow. The rubber construction provides flexibility, accommodating engine vibrations and thermal expansion without compromising integrity. Proper functioning of this line is essential for preventing oil pooling in unwanted areas and ensuring the continuous circulation of lubricant. Regular inspection and replacement help avoid oil loss or contamination risks, which could impair engine performance.
