Engine Ground Necessity in the Big 3?

[oTurtlez 10+ year member]

So I recently got around to doing my Big 3 and unfortunately, my engine ground bolt is under my intake manifold and impossible to reach without removing it. I currently have my Alt charge wire to my batt, and the frame ground hooked up, but I couldn't get the engine one. My question is, is it completely necessary and does it benefit significantly to have it? I used my DMM to see if my ****** was a decent ground and it wasn't so I didn't bother hooking that up. Should I try to find another random bolt on the block to ground to or just leave it as it is? Thanks in advance.

Yes, find a random bolt in a clean "area" that's in a safe location. Use a bolt that's holding a bracket on or something, not a intake manifold bolt ect..

Gotcha. Just wish the OEM once wasn't so inaccessible.

the engine block ground is what grounds the alternator so if the charge leadf is 1/0 the ground should match. If you want after you run new ground just cut the old one

I left both OEM grounds in place for now, and most likely plan on leaving them once done. I'll look for a good bolt later today and see if I can throw that wire in. Thanks to the layout of the engine bay though, Only needed ~3 feet or less of wire so far.

theres nothing with leaving attached just in case you want to neaten up.
