Post the results of your sparkplug check in this poll.

 

I may have got some movement on the torque wrench, but they were tight enough to seal properly. Hex bolts were torqued higher than the spark plugs.

 

Perhaps the more important thing is to get the VINs of the cars that had loose plugs. Maybe the problem is only on a narrow range of serial numbers.

#1924 had plugs installed correctly.

 

I can't vote, but my front 2 plugs were finger tight
Vin # 602

 

When I replaced my stock plugs with Densos, the stock plugs seemed to be torqued well--they weren't easy to break loose, although I didn't actually check the torque.

You bet I used a torque wrench and tightened the Densos down to spec.

I just voted, but to clarify, #2 was loose (finger tight) and the rest were properly tightened.

 

I also changed to Denso a few months back.......#2 and #3 were under torqued but were not that loose....... "00/8821

 

I would have tested mine, but it had fallen completely out!



Seriously, interesting poll...as I said before, I can't explain for certain what happened during that whole mess, but I 100% believe that it all started with the spark plug. I'll be posting pics later on today...

BTW, I should be picking up my car this weekend.

 

FWIW, I was at the dealer yesterday, and asked him to verify the spark plugs. He said "whatfor?". He basically told me he has never seen a loose spark plug in his professional life except as the result of amateur tampering... and certainly not in an S2000.

When I asked him about Hugo (a fellow member) that had a case of the "loosies" , he said that someone had been playing around with the plugs.

Don't know what Hugo thinks about this, but the fact that he has a Spoon carbon head cover might have something to do with it. (Hey, hugo, did you or did you not touch the plugs? ).

 

I changed to the Denso Irridiums about two months ago and the stock plugs were all torqued to spec. I noticed that the manual recommends "anti-seize" compound on the plug threads and I wonder if the factory uses this stuff and whether it might be responsible for some plugs coming loose.
