Valve cover ground bolt size?

[TurboMirage]

isnt it 10mm?

i would say ~an inch long - may not help you but thats how long the bolts were on my 92dx.

gimme a sec.....There looks to be about 10mm of thread length. I compared it with other bolts on the valve cover, which the helms says to be 6mm x 1.0mm. If you stripped it, I'd go with a 8 x 1.25mm, since that seems to be the nice size up thread standard for honda. My engine is a b18, but the standards should be the same for your d16.

which ground are you actually talking about?

You can actually relocate that particular bolt from the 'ground-only' bolt to one of the studs that holds the valve cover on, and have no problems with it...as long as it's grounded to the valve cover in some way/shape/form/fashion, you'll be fine

honestly, i dont know why you need that ground anyway. the engine is grounded in plenty of other places. ive noticed zero difference with it on or off. i have it on on my car but i really dont see it doing anything. but yea like will said you can just go to one of the bolts that holds th VC on

 

[MikeBergy]

yes. one grounds the valve cover, the the other grounds the head.

still unnecessary IMO. VC ground does nothing. i have mine on the bolt (grounded to the head)
