So I'm reading all these threads mentioning loose plugs, and I decide to check the plugs on my 20k miles 2-hand L. Damn, took 3,5 hours without getting the drivers side #3 out. Anyway got that one checked the following day. All plugs were NGK-R TR6 V-Power and all had 0.048 - 0.049" gap, which is consistently more than the advice given on the board for motors with lower pulley mods.

So, just to make sure that the gap was ok, I wanted to confirm that the prev. owner didn't change the lower pulley, but.....it's a 9.5" cobalt blue with a beaten up center bolt and a Napa belt. Hmmm....stock? Not!

So, anybody care to educate me on the #-size of my pulley and the correct plug gap for this?

Not even sure if my chip is flashed. The ECM under the glove compartment has scratches on it but could be reflashed back to stock for all I know. Any tuners in Atlanta which could figure this one out?

Thx a bunch

 

9.5 " = 8lb lower/ civic spare wheel

 

BINGO!!!!

My 6lber is 9 inches in diamater!!!

 

My 4lber is 8.75 inches in diamater!!!

 

Just took a look at JDM's pulleys, and it looks very much like the interchangeble one shown. I suppose as long as idle, WOT and "in between" runs nice and smooth I shouldn't change the plug gap, right?

Thx on the info, one more for my sig.

 

You better find out about your tune. 8lbers with eatons is pretty on the edge.
