Well I have a 01 prelude sh with aem cai, zex plugs and zex dry 55. I went to the track and ran consistent mid 14's ...14.4 being my best. This evening I went out to the tracks, I just changed my plugs, but did not gap them, the were zex hyperperformance with 3 prongs. When I got to the track I was runnin shitty, I couldnt feel a difference but the timeslips told me something was wrong. I looked under the hood, and noticed some oil on my fuel rail, and a little under the spark plug cover. Also when I pushed the throttle a little I heard a very light knocking noise. I cant here it from inside the car. But I can hear ver lightly when I pop my hood and rev the car a bit, I cannot hear it at idle. What do you guys think is wrong? What should I do? Anyone in WPB florida arear that could come take a look? Thanks guys please respond, I dont wanna drive before I know whats up.

dont sound good man .
but the zex plugs dont need gapping .

Probably detonated and broke something while under the influence of the juice...also probable that those funky gimmicky plugs are at fault (for the detonation).

Zex plugs? 3 tips = 3 more things that can go wrong.

I would pull those plugs and read them first. If the tip is white with small specks of silver, you're running lean and probably detonated a few times. If it's black, then it's running rich. A "good" plug should be a light brown or tan.

As for the oil leak, try and pinpoint where it's coming from. It can be something as simple as replacing a valvecover gasket, to something extreme like a blown headgasket (is there white milky stuff when you look through the oilcap into the valvecover?)

Well I would do what you said, but unfortunately I am very challenged when it comes to engine stuff. So I dont really know what to do.

Have you pulled the plugs yet? Go get some NGK BKR7Es and put them in. Tell us what the Zex plugs look like after you pull them.
Edit: gap the NGKs at .035

I believe the prelude uses ZFR plugs so go get some ZFR7F-11 plugs (what my bro runs in his 2K Prelude SH) most places will not have these in stock I get mine from Bap Geon or Glo Autoparts they keep some in stock for me and my brothers cars... We replace them enough!!!! Anyways, read the plug (take it out and see what color it is) If you don't know how to then post a pic and we'll identify it for you but for real the ZEX plugs are pieces of **** throw them away as far as you can. Those and Bosch plugs are the worst thing fora Honda/Acura (IMO). Hope this helps.
