Need for rocker cover to be grounded??

[B18cEG]

hahaha ok sarcasm on the design fault cool cool, my head originally came with the ground strap on the dome nut as are all of the ppl i know that have a b-series in there car, there is also thousands of pics all over the net where you can find the ground strap on the dome nut not on the little tag off the rocker cover although i have seen it on the rocker cover bolt tag a few times, so as im sure u can understand that by looking at over 100 b's (yes with my own eyes) where a few have the strap on the rocker cover tag, you can understand why i am stressing my point.

Just a little imput....

I'm sure with all the engineering honda has to offer they wouldnt have just jammed a ground there for nothing. I might call honda tomorrow and see what they think. This is a fairly heated thread and alot of people are bringing some great arguments to the table. Using your own knowledge to and experience to figure it out. But i think if we work as a family we could probably suss this issue out alot quicker.

Sorry im just putting some love into the air...

Round 3...fight!!!

THIS IS NOT MEANT TO BE A GROUND STRAP FOR THE ROCKER COVER BECAUSE THE ROCKER COVER DOES NOT HAVE ANY ELECTRONIC COMPONENTRY BUT IT IS A GROUND FOR THE HEAD THROUGH THE BOLT THAT IT IS BOLTED ON, DAHH

Earth strap is on the rocker cover itself. Theres absolutly no connection to the head.

why does HONDA!!!! ground the valve cover from the factory?

as the continuity test shows,yes it is isolated from the head,yet honda grounds it......

Maybe back then Honda decided that more grounds is better, and then found that it was not a good idea and changed that with the K series. Oh and having individual coil packs doesn't change the electrical requirements.

Ok, i have tried my best not to double up,

Ok.. ok.. B18cEG we get your point that B engine has the strap on the dome nut.

Now, can you accept the point that the strap is not for head ground, but it's for the rocker cover ground ?

The mystery remains why HONDA put the strap there, although as CRXer (well done with the pix mate) with the meter has shown that the rocker cover is completely isolated from the head.

IMO I think it could be safety measure because some people get zapped from touching the cover??? just me 2 cents.

Twing, B18CEG is correct in what he is saying. If the strap is under the dome nut it is in fact earthing the head. Via going through the stud to the head. If the strap is in that spot it is acutally insulated from the Rocker cover via a rubber washer. ie theres no connection to the rocker cover.

But the 1st post topic, states:

whether or not any engines rocker cover NEEDS to be grounded NOT JUST GROUND WIRES INSTALLED ON OR NEAR THE ROCKER COVER BUT METAL TO METAL CONTACT BETWEEN THE ROCKER COVER AND GROUND THROUGH A WIRE FOR THE PURPOSE OF CURRENT FLOW THROUGH THE ROCKER COVER.

The strap on my B18C7 is actually on the rocker cover itself. Not under a dome nut. The same goes with my B16A2 delsol. In that case its only earthing the Rocker cover. I have seen may other like that too.

yep, plenty of pics ive seen show it earthed on the rocker cover, not the dome nut. but then lots have it on the dome nut.

Ahhh.. i c.. Thanks for correcting.

So basically, there is inconsistency on where the strap is..

[B18cEG]

ok lets settle this,

In my personal opinion from what i have seen "stock cars from honda even before there first service" the strap is under the dome nut, in this case it is correct that the strap is for the head, for the othe handfull were is in on the rocker cover itself, who knows, but honestly i have seen far far more under the dome nut than on the rocker cover itself.

[DLO01]

Na, I wanna keep talking. Means I'll have to do some work otherwise.

Your goal is to have metal to metal contact to the head of motor. Anything else is a waste of time. There is a number of unused threads on the head which you can use.

Dont understand why honda would earth their rocker covers as there shouldnt be any current travelling through it at any point.
