The scoring is the same problem I got in my 01. Mines was caused by the lack of oil from the oil jet bolts!
S2000s from 00 to begininig of 02 has this problem with the oil jet bolts. Unfortunely American Honda wants to keep denying this, because it would be a hassel to recall all those bolts

 

I think that guy Keith is missing something. I highly doubt that only one cly. would be affected. If your still within your warrenty period I would call them on it. A bunch of people have had this problem. Sounds like that dealer is trying to get you to pay for something you shouldn't have to pay for.

I would ask for proof as to why they think that. Just because he's a Honda mech. doesn't make him good...

Doesn't make him bad either I've just seen this before and I'd hate to see you get screw when it wasn't really your fault.

 

#4 cylinder scoring has been proven to be caused by insufficient oiling from the banjo bolts. That's why there is a TSB in EU (not in the US ) and the new parts are completely different.

That mechanic, as good as he may or may not be, is not being honest about the true cause of the problem (or he just may not know about it). In either case, I'll believe that line of crap when I see the "rocks" myself.

Okay, Ive been through this situation plenty of times since I work at an Acura dealership and on Honda and Acura for a total of about 7 years. Yes an air intake will cause premature wear on your engine due to the higher flowing air filter. A higher flowing filter doesn't filter as good as the OEM one and a CAI tends to suck up more road debris and small rocks. However.....if it will NOT cause premature wear and tear in only one cylinder. The only way you can really measure wear and tear is to do a leakdown test. Anything over 15% leakdown is considered unacceptable with the normal being around 5% or less. Total leakdown should also should be within 5% of each other. If you only have one cylinder with a problem then I would look else where for the problem.

 

Word to the wise...

When installing the cold air intake on your S2000, don't remove the entire middle-undertray. Cut a hole for the piping. Removing the tray for a tiny-bit more air-flow is not worth having the filter, as what I would describe as exposed.

I think they decided to print the complete-removal method only for the sake of advertising "no-cutting required" on what was "supposed" to be a collector's car..

 

Damn!! now you've got me reconsidering a CAI for my precious 2004 S.

Is increased air flow from a CAI a given for premature engine wear even if properly maintained ??

I'm considering the Comptech CAI (slightly enclosed), but i'm in this for the long haul with this car.

What say you experts??

 

Not to offend the poster, but I needed to quick get my boots on because it is getting deep. After several years spent racing and now being an automotive service advisor, I see no way for that to be possible unless there is a hole punched through/torn on the filter assembly. I have seen way too many times that a dealer will diagnose the problem being related to an aftermarket add on instead of going through tedious and low paying warranty diagnostic procedure. Even on a customer pay job it is too easy for a tech to blame an aftermarket piece and leave it at that.
Boy, can you imagine how many engines World Rally Cars would go through every race weekend if such companies as K&N etc. built such air filters that suck in rocks, dirt, mud, etc! Their company would have been filing chapter 11 long ago.

I will not get the Comptech CAI anymore because someone said that it causes premature wear on the engine.

Can this be confirmed or rebutted by any knowledgeable person, because I really wanted this CAI.
