have i lost my mind?

the S2000 had been starting sluggishly. got a new OPTIMA yellowtop battery. fires right up. seems like the car runs better. crazy?

looking to adjust my valves. read where a guy who did the procedure said that his spark plugs were not tight when he took 'em out to adjust the valves. (this is part of the procedure to adjust the valves on an S2000.) i figured that i would check my plug gap, and see if they were loose. the gap was perfect and the plugs were a nice light brown. they were not torqued down. it was so easy to ease them out. i re-torqued them to spec (18 ft-lbs) and the car now runs like it is on fire. crazy?

need some help thinking on this one. does my butt dyno need checking? any shade tree mechanics out there? the plugs were not loose but definitely not torqued to spec. could this have been causing a mis-fire?

Believe it or not BB the battery is the heart of a car. Most people think it's only to start it up, but a weak/bad battery will affect the electrical performance. As far as the plugs not being torqued right not a issue with performance, but if they loosen up you have a possibly of a plug popping out a messing up the cylinder head. The NGK auto class I attended said NOT to use anti-seize on the threads because it would get in between the plug threads and cylinder head threads causing a false torque reading.

i considered this in my thinking. not only did bb fire right up, her performance seemed improved.

i thought maybe i could be getting a mis-fire or compression loss. when i un-wrenched the plugs, i met hardly any resistance at all.

i never use anti-seize on plugs, although i have heard it recommended more than once. funny about things...the procedure for re-torquing the rear axle nuts calls for greasing the face of the nut to get a true torque reading; NGK says to not use a lube on plugs in order to get a true torque read. i guess all nuts are not created equal; sometmes the little things are the screwiest.

nontheless, bb runs like brand new. just turned 68,000. what a great car.

now, here's a spark plug nightmare:

The greasing and torqueing thing kinda depends on the metal compounds, for instance hard metal(stainless steal stud) to a soft metal(aluminum cylinder head) Of course many people have a different take on anti-seize and other lubricants.

Seems like the axle nut is a different nut to crack. You are torquing against a flat plane so grease there is desirable. You need an accurate reading. The idea is to provide the proper clamping force for the bearings. With a spark plug you are only ensuring the cylinder is tight in the hole so it won't back out or affect performance.
Yes?

spark plugs = 18-20 ft-lbs
axle nuts = 220-240 ft-lbs

the engineers that built this thing figured the torque values. gotta go with what they and the other experts (Bilman, who says you need to grease the face of the axle nut) say.

i re-torqued the rear axle nuts on bb. they were much easier to crack than they were to torque. at the end you got to stake your nuts (but not like that guy in china). beware! nudity and graphic violence in progress: http://www.mirror.co.uk/news/weird-n...artist-2719065

ya gots to torque your stuff to keep it from a-comin' loose is all i know. gotta torque the axles so your bearings won't creak or come apart when you are flyin'. gotta torque the plugs to keep 'em from backin' out causing you to lose compression or spark, or screwing up your head. $$$.

i just wanted to ask opinions as i def noticed an increase in performance; but i am nuts. i can get improved performance from an oil change.

valve adjustment is next.

Just wait until you have this done. Had this done in the spring and the car runs better. Also added to the butt dyno.

i will be doing this. it is always a PITA but kinda fun once you get down to it. i got me some fresh angled feeler gauges and am awaiting the special Honda 10mm adjustment tool. love some tappets.

my butt dyno is a very sensitive creature. gratuitous bikini photo warranted?

Yea BB the rear part of the V/C with the wire harness is my worst part. A friend would be nice to hold it away.

is that an affirmative?

tks for info on valve cover and wire harness. i am sure that it will be the usual adventure.

valve adjusting tool came today in the mail box. soon.

i would suggest to everybody to check the torque on their spark plugs.

i think we are passing the boundaries of good taste. however, bein' this is cosomo's first time, i think we can let it pass.

the wheels are a problem. i do not see a problem with the tail.

chocks away, bucko!

Is this within the boundaries? Another case of eyeball torque at a critical phase!

Sorry Cosmo, had to delete your pic. As much as I enjoyed it, some other members and guests might not.

No worries. I am not "torqued" off!! Lesson learned.
