Thanks for all the info. Unfortunately I can not be sure what speed I was doing, guess as it hit the limiter (However it is done), it must have been more. Thinking about the road, it could have been closer to 50mph+.

Gona really want to check my retainers now, but as mentioned, it is not a quick job, and guess there is no way to check without physically removing the retainer itself, not just remove the head.

Thanks

 

So did you hit the limiter or not? Because if you did, then you didn't overrev it. If it made a higher pitched noise than you get at 9K, then you did. It's like if you mis-shift and end up in neutral and plant the throttle. It'll seem like something terrible has happened, the car won't accelerate and the revs will shoot up and bounce off the limiter. But actually it's fine; it's doing what it's meant to do.

I'm surprised you even got it into 1st at any speed.

 

If you are worried why not get a good indie to check the valve adjustment and see if anything has moved?
They can have a look at the retainers with out stripping it as well?

 

Yeah just waiting on a local s2000 specialist to get back to me on cost for checks. Iv read some of Billmans threads on how to check without removing the retainers. So think I will take the rocker cover off and see if there are any signs of distortion.
If they retainers need to come off, I will just replace them.
Believe the only real way to check though is to strip them out as the cracks start on the bottom of the retainers which is not visible with them in place.
Damn you left arm for not knowing where 3rd is!

Dembo, Yes it did hit the limiter. as I lifted off the clutch the revs went up to where the red zone on the rev counter flashes. Heard a single bounce by which point I was already back on getting the clutch down and finding a higher gear.

 

You only have a rev limiter if you do it with the throttle going up through the gears - if you do a mechanical overrev there is no physical limiter on this engine. That's the danger of a miss-shift when coming down the gears.

 

WHS. Were you on the throttle? I assume not as changing down, but then 5th to 3rd is weird. If you weren't on the throttle, then it couldn't have hit the limiter. If you were, and you heard it bounce, then you couldn't have overrevved and therefore have nothing to worry about.

 

If you had bent any valves due to valve float you would know about it already.If it bothers you and you decide to change the retainers any way then let me know.Ive got a full set of uprated springs and retainers for sale with very little use and they will probably be cheaper than just the retainers from Honda.

 

1. Don't block shift unless you're really very, very good.
2. You can check the retainers, but the valve heads might fall off further down the line without warning.

Or they might not, since it only marginally increases the metal fatigue on the valves. Check the retainers if you like but if it ain't broke...

 

I thought skip/block shifting was a no-no on the S2000 gearbox? I remember a thread about it no so long ago.

Nick - what do you mean by being very good and why?

 

We don't have the AP2 over here only the 2.0L but it will have the uprated retainers.
