How to align the timing chain of the G4NA engine?

[AddysonFitz]

The camshaft gear also has three marks: two groove marks aligned with the cylinder head plane, and the dot on the gear aligned with the black chain link on the timing chain. The TDC mark on the crankshaft gear should be aligned with the mark on the oil pump. First, rotate the crankshaft to the top dead center (TDC) of the first cylinder piston. You will see alignment marks on the timing gears. Rotate the camshaft so that the first cylinder cams are in the position where the valves are closed. Then, locate a round hole at the front and check the housing to find the alignment mark.
