Our process


When we receive an old engine at HM GEM Engines, our team quickly dismantles, chemically cleans, and inspects it to ensure that it meets our stringent reusability guidelines. 

Core components are also cleaned for inspection, including:

  • Cylinder heads
  • Crankshafts
  • Camshafts
  • Connecting rods
  • Oil pumps
  • Rockers
  • Valve covers
  • Oil pans 

Items including pistons, rings, bearing shells, timing components, valves, lifters, gaskets, and seals are discarded, as these will be replaced with new components during the reconditioning process.
