What actually is a custom valve adjustment? I do my own adjustments to the lowest Honda specs. Does this mean that I have just done a custom valve adjustment?

Also forgot to ask if the retainers have been upgraded from the 00-01 year S? Or is this still a problem for the 02-03's?

The retainers in the F20c are exceptionally well for the engines layout. Infact, when RSX type-S owners upgrade their valve train they use the same retainers from the F20c. They can withstand the 9000 RPM redline but become less reliable with mileage and abuse. In my case or anyones case of a slight over-rev is where they CAN fail. I'm not sure Honda has addressed the retainers in the 02+ years simply due to the fact that they are sufficient for the engines application. Also, there have been stories of S2 owners not even knowing that they had broken retainers and later find out. Its really cheap insurance for someone to check them out. Another thing, 10500 RPM's where floating occurs doesn't mean you cant damage a retainer at 9500 RPM's! When the S2 is driven within its standards its a very reliable vehicle. In my situation, I'm looking to excercise all precautions. I mis-shifted, over-reved slightly and am prepared for my vehicle to get checked out.

When this "best mechanic", doesn't even know the actual redline of our car

to do 10500 rpms in 2nd (where honda has told us float occurs) you would need to be doing 77.5mph.
krazik
Let me give you some light as its pretty dark where you are sitting.

Initially, I was riding around in my S/C'd car with split retainers that I luckily caught before major disaster hit.

So, does 90 bucks seem a lot to you for a valve adjustment and check? Or would you rather pay thousands of dollars for a new engine. I'd pay $200 if I had to, to catch any split retainers before diaster hits.

And say Bill is a self-proclaimed best s2k mechanic. you are absolulutely incorrect. Bill got his reputation through the customer satisfaction that he gives his customers. I've worked w/ him before and I know how he works, so back off on your big mouth.

So when does the rev limiter cut out again Krazik? 8900? You know when the rev limiter is working you hear the engine sort of hold back on the RPM's up and down repeatedly, so now, when does the rev limiter actually come on Krazik? I want some accurate numbers since you are the RPM master...

Hey Venomous S do you want the rev limit or the fuel cut off because
I know about both


Just thought I'd add my $.02

1) an over rev can happen to anyone I don't care how good of a driver you are
Shite !!! happens so to telling someone to pay attention and stop mis-shifting is
like playing arm chair quarterback and really not needed.

2) Billman as stated above is not self-proclaimed he is the best as judged by
myself and many others whom have had experience with other mechanics
and know the difference when it comes to customer service.

I speak from experience because I came in for a valve adjustment and Bill
noticed the retainer being out of spec, and after some more inspection
he found that it was cracked. I was there when he found the problem and
IMO I doubt that it would of been found by your average mechanic, its only
because Bill works on your car " AS IF IT WAS HIS " at that's how he does all
of his work.

3) Bigsalgt has free choice no one is telling him what to do, he is doing this for
peace of mind which is a good Idea I think $90 is better then thousands of
dollars for top end and even more if the valve drops.

4) BTW if I remember correctly Woodwork says the engine lives @ 9500rpms
so there's something to ponder about

Just my 2 cents...Since we have several s2000s in development we often seek for assistance. Those fabricators and engine builders involved are some of the most highly skilled individuals in their field. I have pro race car builders calling Billy for advice on the S, so go figure if he knows something or two about the s2000.

Several factors will influence the point at which valves begin to float (density altitude, valve spring condition and tension, valve train friction, quality of lubrication, and so much more).
The valves can begin to float as low as 9,600RPM, and piston to valve interference is pretty much guaranteed at 10,500RPM. The engine will come apart at 10,800RPM. These are basically the numbers provided to me by the Honda model engineer.

One thing that I don't understand, however, is your apparent animosity toward Billman. If this is a misunderstanding, please let it be known.

Frankly, Billman has contributed a lot to the forum and doesn't deserve it.
His expertise is not in theoretical BS, it's in the fact of the matter stuff that means the most to the larger population on this forum.
He has a lot of experience in diagnosing and repairing problems with the S2000 (and I'm sure many other cars as well), as well as a lot of great tips and how to's that are invaluable.
No one person is an expert on everything ... that's why we come together on this forum to learn.
Very well said! I myself feel the same way, why else would I have posted this question in the first place? If I had all the answers I certainly would have not posted it. This site is great for many reasons, one of the best reasons is for advice alone. Look how many people have posted on this topic with great advice and knowledge of the engine itself. If all that comes out of this is a simple 1-2-3 valve adjustment then so be it. At least the retainers were checked and I can live in peace once again. After reading the past posts regarding Billmans reputation it only furthers my obsession for the valve train to be examined by him!
