Valve adjustment

I don't know why there are different maintenance requirements for the same car in different markets.
Interesting the EU dealer check list shows 27,000 miles for a valve adjustment on ALL Hondas, not just the S2000. Of course that also specifies a 9000 mile oil change interval and a timing belt replacement at 92K -- good luck finding one of those.
I'm sure you UK and EU guys have the owner's manual which before 2006 has the maintenance schedule. Does that specify 27K for a valve clearance adjustment and anything at all about a timing belt?
On North American cars the S2000 service interval for the valve adjustment is every 105,000 miles unless noisy. That's for both the 2.0 and 2.2 engines. But the 2006 and later 2.2 (AP2) engines are known for dangerously tight valve clearances (perhaps from the factory) which will burn the valves as these engines run leaner than earlier specs. For those cars it's critical.

We don't have the 2.2l engines here, so it's moot.
I guess it's a way for the euro dealers to obtain extra income.
Maybe it's because the cars are driven harder here? Higher speed limits, tight, twisty roads requiring more braking and acceleration etc. Also the very bad congestion...

Evidence suggests it's the DBW setup that is tuned to run lean, not the size of the engine but I have no idea if the DBW AP1 engines have the same lean-burn as the DBW AP2 engines. Won't hurt to check your valve clearance regardless of what engine you have. Checking takes hardly any time at all but while you're in there just set them all to spec.

All good to know.
I'm looking at one that has very light bubbling under the paint work on the arch, not sure if the rubber seal is still on as I hear that hides and causes alot if the rust. If factoring into the pricing of buying is it eotty buying one that has light rust?
