How to Identify If Your Diesel Engine Needs Repair

An engine overhaul is a major diesel engine repair where the entire engine is rebuilt. During the overhaul, all components (bearings, pistons/liners, cylinder head, turbo and injectors) are inspected to ensure they are within the manufacturer's tolerance. Any parts that fall outside of those tolerances 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 mechanic 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.

There are two types of overhaul:

In-Frame: where the repair is done with the engine in the chassis

Out-of-Frame: where the engine is fully removed from the vehicle for repair.

If you notice any of these problems, it is 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. This could be due to rod or main bearing wear.   A fuel or coolant leak can also contaminate the engine oil, which could lead to high oil level in the crankcase.
  • Excessive oil consumption. This is a leading indicator of internal engine wear.
  • Excessive blow-by.  This happens when the piston rings are worn, causing the engine compression to escape past the piston and fill the crankcase with excessive pressure.
  • Your engine has dropped a valve. This is an all too common and critical fault of a diesel engine.
