What's wrong?
The high pressure engine oil line on 2005-2011 Ic Bus Fesb, Resb, and Cesb school buses carries engine oil under pressure while the I-6 engine is running. That oil flow helps the engine stay lubricated and supports engine systems that depend on pressurized oil. The line has to stay sealed while it handles heat, vibration, and engine pressure.
On affected buses, the line does not hold that pressure as designed. It can develop a leak, and in a more serious failure the line can rupture. When that happens, engine oil escapes from the line instead of staying inside the engine system. The defect is the line's loss of sealing under operating pressure.
There is no warning sign before failure. After a leak starts, a driver or technician can see fresh oil around the engine area, smell oil, or notice an oil-pressure concern.
