What Are the Signs That an Engine Needs to be Overhauled?

Engine overhaul is a necessary maintenance step performed when an engine’s parts begin to wear or become damaged, resulting in significant performance decline of the engine. Signs that your engine requires an overhaul can include unusual noises, blue or white smoke coming from the engine, or frequent breakdowns. However, the signs can also be more subtle, including:

• Low power
• Poor fuel efficiency
• Hard starts
• Rough idling idle
• Low compression
• High oil consumption
• Wear metal in the oil

If you are experiencing engine problems, it is best to take your vehicle to a qualified diesel mechanic so they can recommend the specific repairs, replacements, and OEM parts your engine needs. See Stewart & Stevenson’s locations for service and repair of Detroit engines here.

However, sometimes a piecemeal approach to part replacement and repairs is neither the most efficient nor the most cost-effective approach to maintaining your engine. The StepUP program provides four pre-packaged overhaul kits based on the most common replacements needed for the DD Series, Series 60, and MBE 4000 Series engine lines, backed up by Detroit’s guarantee for engine performance for 1-3 years.

Is an Engine Overhaul Worth It?

Benefits of an Engine Overhaul

Though an engine overhaul may feel like a hassle, there are several compelling reasons why an overhaul will save you money in the long run. Getting your engine overhauled will enhance engine power and improve fuel economy, ensuring smooth operation altogether. The Detroit StepUP overhaul kit will save you time and money due to the fact you will have less unplanned downtime and longer engine life, preventing the need for a costly full engine replacement down the road. It also lowers your labor expenses by reducing the likelihood of unexpected breakdowns where employees cannot work. Lastly, the kit comes with several warranty options.
