What happens here

After all machining and component preparation are complete, the engine block is moved to a dedicated assembly room. Here, the long block is meticulously assembled, involving the installation of the crankshaft, connecting rods, and pistons. Every critical tolerance and clearance, including main and rod bearing clearances, piston ring end gaps, piston-to-wall clearance, piston-to-valve clearance, lash settings (for mechanical lifters), and oil pump pickup tube clearances, is measured and documented on a detailed build sheet. The reluctor wheel (58x) is tack-welded to the crankshaft to prevent rotation and ensure precise timing, a common failure point if not secured.

Goal: Assemble the engine long block with meticulous precision and documentation

Tools and materials

  • Engine Stand — Supporting the engine block during assembly
  • Hand Tools — Wrenches, torque wrenches, micrometers, dial indicators, ring gap tools, etc
  • Assembly Lubricants — Lubricating components during assembly
  • Bearings — Supporting rotating components
  • Connecting Rods — Engine rotating assembly components
  • Crankshaft — Engine rotating assembly component
  • Piston Rings — Sealing combustion chambers
  • Pistons — Engine power-generating components
  • Reluctor Wheel — Crankshaft position sensing for timing

What they say

water in this thing is really clean um then once it comes out of there we'll swing it over into this tank here we have a hot water heater that allows us to not flash rust the part so if you put cold water on a uh freshly machined comes out hot you put cold water on it'll flash rust and look like i didn't know that was a thing yeah yeah for sure so um we have hot water that we can spray it down do all the final like brushes through it just like the absolute last final stage of the of the initial cleaning is done in here from there it'll go onto an engine stand then it will get in the assembly room we will then take lacquer thinner lacquer thinner the cylinder walls and do like a kind of you know real fine fine cleaning of the cylinder walls with the atf the cylinder walls as well has a high detergent in it that just allows us to really get that any final debris that's in that cross hatch out of it so again the cleanliness of the of the build is paramount to the end results and i can't stress that enough it's like
