Crankcase, oil pan, crankshaft, connecting rods, pistons and timing gears.

Not really happy with the render, but the complexity is too much for my hardware, so I only gave it one go. Pistons are gold to imitate titanium nitride coating, but in reality it would be ceramic coated.

I did not include wrist pins, main bearings, or piston rings. They don't really serve a purpose in the assembly besides accuracy.

Oil Pan has been modified to provide a boltface for a dry sump pump.
