My S is still new to me and I've mis shifted a few times. It's revved up to highest I saw was about 8800 on my ap1 which was scary!

However when I downshift I engage the clutch slower and if I feel the motor pull (Rpms shoot up) I immediately push in the clutch. Everytime including the 8800 rpm 2nd gear rev the clutch never got fully disengaged. I hope that the extra little caution with slipping the clutch saves my engine when this happens.

 

Pulled the valve cover today and carefully inspected each intake-side retainer. The "center" of the retainers were all clearly visible and spaced the same distance from the surface of the retainer. I'm going to pull it again every 400 miles or so and check from now on. I'll definitely be buying the parts to upgrade to AP2 retainers for peace of mind, but it looks like I avoided doom this time.

 

You may want to just replace your valve train. A mechanical over rev may not have done any visible or noticeable damage but later down the road even the slightest bend in a valve means its only a matter of time before you drop a valve. Then your out a whole motor. I'm just speaking from experience and I didn't read what everyone else said so sorry if I repeated what anyone told you already. I wish you luck with everything.

 

You'll be fine, get a valve adjustment ASAP though. I over-revved my ap2 once racing a friend and got a valve adjustment the next day. a few of the the retainers were loose but other than that, no problems. If I had kept driving I'm sure there would've been an issue with stuff coming loose

 

I appreciate your input, but it's cracking the valve retainers that causes you to drop a valve. If a valve is bent, it's usually painfully obvious from the valvetrain noise.

 

Hey all, just an update on my situation. I did a compression test today and all 4 cylinders were within 2-3 psi of 210. I definitely don't hear any additional valvetrain noise so I'm pretty sure my valves are alright. I'll make another post when I replace the retainers to let everyone know whether they cracked.

 

This past spring we replaced the retainers and keepers on my car. I have never overreved it, but it felt like the right time to make the upgrade. The parts are cheap even from a Honda Dealership. If I remember correctly the parts were around $100.00 including new gaskets. To me that is cheap insurance.
