What is done during an engine rebuild?


An engine rebuild is a great option for vehicles that are experiencing serious engine trouble, but are in otherwise great condition. Oftentimes, an economically sensible option is to install an engine from a different vehicle that has been fully rebuilt and is ready for many years of regular driving. When purchasing a rebuilt engine, be sure to choose a shop that specializes in giving new life to old engines. Here are five steps that occur during an engine rebuild.

Removal and Inspection

To begin the rebuild, all engine parts will be disassembled and cleaned. In some instances, steam cleaning will be done. Following a thorough cleaning, all parts will be closely checked for signs of degradation. Then, parts that need machining will be prepared for that process.


Among the machining tasks that will be completed as needed are: boring/honing the engine block, crankshaft grinding, and micropolishing chamfer oil passages and bearing surfaces. If necessary, valve seals will be recut and the technician will resurface cylinder heads. Overall, machining will return parts to their former smoothness.


During engine reassembly, it's standard for new main and rod bearings to be installed. Other new parts typically include: timing belt, seals, and gaskets.


Once the engine has been completely reassembled, the technician will test it for proper oil and compression. The technician will also check for any leakage and make sure any such issues are fully taken care of.


To complete the process, the engine will be installed in the vehicle, at which point there will be final testing to ensure smooth operation.
