Solution
Title (customer effect)
Mack Chassis - Equipped With A Variable Geometry Turbo ( VGT ) - Oil Leakage
From Turbo / Oil Or Oil Residue Observed in Charge Air System
Cause
Issues with the Charge Air System may result in the presence of oil in the Charge Air
Cooler ( CAC ) or intake piping.
Solution
If oil is found in the Charge Air System or the Turbo Compressor Outlet, the turbo
should not be condemned immediately.
1. Review SNM15-012 and follow all guidelines outlined.
2. Ensure that the turbo itself has not experienced a failure aside from the oil leakage.
• A major oil leak from the turbo would more likely be an internal failure.
3. Check repair history and verify that there were no previous failures that could have
left oil residue in the system.
4. If the issue persists following repairs or there are no issues found from SNV
guidelines, further diagnostics will need to be performed to determine the source of the
oil.
