How to identify if your engine needs an overhaul or repair?

An engine overhaul is a major diesel engine repair that involves inspecting all components (bearings, pistons/liners, cylinder head, turbo and injectors) to ensure they are within the manufacturer's tolerance. Typically, an overhaul requires the full removal, disassembly, assessment and repair of an engine. During the inspections, any parts that are found worn, faulty or out of the manufacturer's specs are replaced.  During disassembly, the engine is cleaned thoroughly to remove built-up grime and debris. Since your entire engine is being taken apart, it’s much easier for our mechanics to identify problems and replace malfunctioning parts. Once everything has been cleaned and the necessary replacements have been made, the engine will be put back together and set back into the truck.

If you notice any of these problems, it is likely time to bring your heavy-duty truck in to get overhauled or repaired  immediately:

  • Your engine has spun a rod bearing. This is one of the worst failures that can occur inside your diesel engine.
  • Your engine has very low or no oil pressure. A fuel or coolant leak can contaminate the engine oil, which leads to a high oil level in the crankcase.
  • Your engine has dropped a valve. This is an all too common and critical fault of a diesel engine.

What about engine conversions?

Performing an engine conversion takes time, knowledge, and patience. That's why we start every project with a conversation with you so that you understand the scope of the project. Before we dive into the specifics, we want to find out your goals for the conversion so that we can point you in the right direction as the inevitable onslaught of choices come up along the road.

The biggest component of an engine conversion involves all of the new electrical work. It is the most time-consuming, the most challenging and often requires the most skill. We'll keep you informed throughout the process and ensure that you're aware of the work we're doing, adjustments to timelines, budget, and more.
