He said he didnt hit redline in 3rd. He was at 6-7k rpms when he shifted into 2nd.

Look out for bad idle, white smoke, irregular noises, loss of power, and its a good idea to do a compression test, just in case.

I'll be the 2nd to say his car is fine.
Why woul the smoke be white? If oil is getting past a bent valve wouldn't it be blue?

I'm a bit unsure as to why people are always so unwilling to get things checked out. The small amount of coin it costs for the peace of mind is well worth it in itself.

If in fact the engine was indeed overreved, damage may have occurred. Do yourself a big favour and take an afternoon of your time to get things looked at properly and perhaps save yourself an engine. After you've done that, come back and post about how everything checked out just fine and that you're motor is perfectly healthy

Just for the record, a compression test will not show a broken retainer. If you dropped a valve already, you'd most likely know it. What AP1's are concerned about is a broken retainer that will slowly crack further and eventually drop a valve. This has never been documented in an AP2 yet, but better safe than sorry. The problem is finding someone who can check retainers. More than likely your honda dealer does not know how to do it properly, most people dont. Billman has a write up on it. POst in your local forum and look for an s2k mechanic.

Thank you elusiv and Jsmply. I swear, half of the posters here appear to just be making things up! "Compression tests"....."it's just fine if it runs ok". The guy posted here for advice, not speculation.

jdmgpw04: Post up in the Southern Cal forum and someone there can help you to find a competent local mechanic that can check this out. It should only cost a couple few hundred dollars or so.

Just to clarify...

You've noted the car runs just fine, and thats good to hear. However, that doesnt rule out the fact that your retainers may not be cracked or broken.

You're expecting a gradual decrease in performance and that simply might not happen. Your motor can be running stronger than ever in one instant, and in the next see the catastrophic effects of a dropped valve as Jsmply had mentioned. You driving the car hard to confirm to yourself that nothing is wrong may in fact be placing more strain on already broken retainers.

In short, if I were you I would stop driving the vehicle and tow it to a dealership. If you *must* drive it, then I would drive it with a light foot until then.

If you have doubts, check this post:
https://www.s2ki.com/forums/index.php?showtopic=437271

Note that at the bottom of the first post, it's stated that although all the cases of broken retainers "all cars had zero problems."

Dont mean to spook you, your engine may very well be fine. But the fact that you asked how much a compression test would cost, tells me that you'd definitely lose a few nights sleep if you blew an engine.

I'd rather not take a gamble with other peoples engines and tell you, 'all is well.'

Good luck!

just wondering why it is less likely? are the retainers stronger, or is it purely the fact that the 2.2L does rev as high?
