How would someone make the mistake of doing this and why is it detrimental?

I am regrounding my engine. Would this diagram of my engine bay create a ground loop?

The circled areas are the grounding points. The red lines are my routing of the ground wires.

I would suggest grounding each component separately. Absolutely minimally, remove the cable between the left shock tower, and the intake manifold, but you will still have imposed ground loops.

A ground loop occurs when there is more than one ground connection path between any two components. Having more than one path to ground forms the equivalent of a antenna which picks up interference.

Would this be better? The ground wire are one to one now.

It is better, yes, but not the best. You should be fine with this design.

Did my description make sense?

Good Luck,
