Eight Signs It’s Time for an Overhaul

Your truck is built to work – just like you. And the last thing you need is to get sidelined on the highway or jobsite with a worn-out engine.

If you’re experiencing any of these performance-related issues, an overhaul can breathe new life into your engine and get your rig back on the road fast:

1. Blue or black exhaust – One or more cylinders may be burning oil, or your fuel is running too rich or lean
2. White exhaust – Coolant may be burning in one or more cylinders
3. Engine knocking – Combustion timing may be off in one or more cylinders, or oil contamination may have occurred
4. Reduced acceleration/hard start – Possible loss of cylinder compression
5. Increased oil consumption – The engine may be leaking or burning oil; either situation isn’t good
6. Low fuel economy – Loss of cylinder compression or over-fueled cycles
7. Low oil pressure – Oil may not be reaching all the components
8. Poor engine brake performance – Possible loss of cylinder compression
