Today was going to be my last day with my ep3 before I sold it because my new evo has finally arrived. I took the 03 si for one last rip against a wrx on rte 9 (which I beat), but in doing so with all the noise, I bounced it off the rev limiter for a bit in 3rd gear (8000 rpm). I felt as if something wasn't quite right after that. As soon as I exited I noticed a knocking mechanical sound. Now the engine still felt ok, strong and smooth. Just a noise coming from within. Also got engine codes, cylinder 2, and cylinder misfire. These codes started the second time I started my car. Not immediately after the incident.
Background:
Boosted (11 psi) with a revhard turbo kit, Hondata K100 chip (raises rev limiter), AVC-r boost controller, etc... etc...
My Theory:
Because I bounced it off the rev limiter for a solid2 seconds (I have never done that before), I am guessing my valve springs are not up to snuff and at 8000 rpm, I got some serious valve float, resulting in some interference with the pistons, damaging the valves...
Please Help:
Would my theory cause the knock I hear and the cylinder misfires? What do you think it could be? Thanks for your help guys.
