To answer your question, yes it is a potential problem. In a perfect world it would be ok, but corrosion being what it is....

1 ohm is a lot when you only have 12v and some devices can draw 15-20 amps.

There should be only one main ground point and it should be made of plated copper for reliable connection. All other grounds should radiate from there. The engine block should be one of those. And there should never be multiple paths for any single ground to get back to the main ground.
