hi guys just a simple question...i just wanna know how to put in the spark plugs indexed...

i.e. should the GAP of the spark plug be facing up, down, left, right or what???

and also just curious on what u guys used to clean the spark plugs cause it had fuel on the shaft from when i was cranking my car from my previous problem..kersosene? water? WD40? or what??

thanks all

I use to index my bikes plugs, but it's been a while & i can't remember 100% but I THINK the gap points to the exhaust side of the head ( I think it had more to do with the shape of the combustion chamber). There was a thread on this a little while ago but I couldn't find it, sorry. There was one in the 2nd gen forum that said exhaust side.

As for cleaning them..... do you mean the electrode ? I use a little bit of fine wet & dry sandpaper and a lot of compressed air (as you don't want any abrasive in the bore ) or do you mean the porcelin (white) part ?I just wipe it clean with a rag.

Clarification needed for the indexing question.

i mean every part that is IN the combustion chamber...i.e. the parts u con no lonmger see when they are screwed in...

I just clean the gap up with wet & dry and the blow it clean with air. If I pull a plug and it's past just a "quick clean up", I replace them:shrug:

There was a good thread on this last month. .but Mr. Immaturity Barry Hallstead is systematically deleting every thread he has posted in, and thus deleted a lot of every one else info aswell .. so unfortunately im no help.. Well done Barry..

Woo was refering the index post for 1st gens. so this may not apply to 2nd gens.
I remember him writing that the hook part on the plug should point up. To get them in the right position, you may have to take them in and out a few times so they all face up.
I drew a line on my socket piece to indicate that the plug is hooking up.
Hope that helps.

When Indexing plugs it is generallly found that if the gap is pointed towards the intake valves it will generate a couple of HP more then pointed toward the exhaust valves.
with the 3 valve head you IMO would want to point it right in the middle towards the bit between both intake valves.
on a 16 valve head you migt as well do the same between the two intake valves.
I know on VN headed V8's they find best pointed on chambe side of the intake valve not the exhaust side of the intake valve for best results. It's said that this is where most of the fuel mix enters. Apparently it saw 6Hp at rear wheels on this Torana but that could have just been from leetign the car cool ETC. but It is well know to provide a sweeter burn.
