replace the retainers, its highlyun likely there is no other damage considering you depressed the clutch immediatly. when your replacing the retianers you cna do the visual inspect and you can do the visual inspect and your answer will be in front of your eyes

Stop driving the car now. If you are getting a CEL, you almost certainly bent a valve. It's probably a misfire CEL.

Sorry to hear about the money shift.

I know of a guy who did the exact mistake you did. After just two days of wondering if there was damage done, and wondering how long till it shows...how much is it going to cost etc etc, he went and traded his S2k in at a dealership. Got an auto G35 haha

there's no fix in a can for overrevs, tear it apart before something breaks and bust your bottom end

Yup, bent valves would be my guess. Run a leak down and find out for sure. The idle fluctuation is a symptom of bent valves. The severity of the idle problem would depend on how many valves are bent.

So how does Supertech valves (stock size) w/ stock valve springs and 04 retainers/keepers sound?

Any advantages in going with Supertech as opposed to oem valves?
