In Puget Sound we have a very similar climate. However, my car gets readjusted at least once a year, so maybe that precludes the corrosion building to the point of freezing the bolts.

 

Crap, I'm really scared then. Our 00 with 104K is going in for it's first valve adj tomorrow. Don't think it's ever been over-revved. Are there any serious symptoms that would tip it off? The car idles fine, it just ticks a little louder than normal which may just mean it's slightly out of spec.

How costly is it if the retainers need to be replaced, is it still drivable in the meantime or will you notice a severe loss in power? How does the AP2 part fix this, is it a factory design flaw?

 

Nope. It just runs 'til it breaks.

I'll point out that I *know* I overreved my car (mildly) at least three times. When I replaced my retainers I inpected them carefully and found no sign of damage.

It's not a design flaw that the car breaks when you overrev it. That's why they call it OVERrev.

 

Point taken, the guy doing the adjustment tomorrow is pretty experienced so I will just make sure he looks carefully as he's doing the adjustment. This is just the first time I've read about this and the car is getting old so I was a bit freaked out.

 

interesting point...very little chance that it is a problem billman overlooked...

but of course, i'd like to hear what he has to say about this.

 

Actually, if there was no damage, it wasn't a money shift.

I think we all make more mistakes when we're tired or lack focus for any reason, but there is a big difference between missing a gate and catching the mistake before trashing the engine, and throwing a genuine money shift.

What I was asking was whether or not you know of anyone who's thrown a real *MONEY* shift (over reved enough to do damage) on the track or on an autocross course. ???

I myself am far more likely to miss a gate when driving casually on the street than I am when driving hard, becaue I'm far more focused when pushing the car (tired or not ), and I think everyone is (probably) a lot more focused when on the track or autocross course.

When I miss a gate now, it's because I point my palm in the wrong direction, and when that happens it's invariably the result of a brain fart (total loss of focus). Mike, I wish you'd try it and let me know what you think.

 

When I got my car there was still some question about whether or not this could happen without an over rev, so for about four years I checked my retainers at every oil change (it's an easy check that only adds a few minutes to the effort), but now we have accumulated enough data for me to abandon the routine checks. Even if you ride the rev limiter it doesn't hammer out the retainers the way an over rev will, so as long as you don't miss a shift and get a mechanical over rev you really don't have anything to worry about.

One of the nice features of the Modifry Redline Shift Beeper is that it has a high RPM memory, so if you do miss a shift, it records the peak REVS that were reached, and you can look at the value later to determine whether or not you actually over reved or over reved enough to worry about.

Yes, several, that I know personally. But not in an S2000. I also know that at least one or two of the R&C regulars have done it while racing in their S2000s.

 

Same here on my last three

 

Spring installed height is the same with either retainer. I don't recommend using AP2 springs in an AP1.

All you need is 2.2L retainers and keepers (or cotters as Honda calls them)
