One of the grounding points seems to be missing a bolt.
What type/size/threading is it?
Just put one in that fits i thin a 10mm fits
It ended up being an M7 bolt.
I dont under stand why that point needs to be grounded if the.valve cover sitts on a rubber gasket. there is no metal to metal contact with the head?
My guess is that it is for the spark plugs. Even with the valve cover having a connection through the bolts to the block, the wires could contribute for additional current flow.
The wire is pretty thick, like 8 gauge I think, so by design, I’m thinking there is quite a bit of current that needs to be grounded. The silly little wire to where I needed the screw was probably to get more contact area, as the terminal ring with the big wire connects mostly with just the nut.
After I change out my battery ground wire, I plan to change this one out with new wire and terminals, maybe going up a gauge.
