That is somthing that can be checked with the head in the car.

I have not seen or heard of an AP2 with this problem, only AP1's..

Did you ever mechanicaly over-rev the engine?

Never mechanically over - revved i did buy the car used but it drove fine for over a year until the CEL came on.

Whats the milage on the car?

I have seen a few around 100k wear out their valve guides and then damage the valve seats... but that seems more common on the exhaust side.

just to make sure, your car is an ap2 right?

you might have moisture on your gas tank as i have experienced it last week coz i wasnt using it for 2 months, brought it to honda they told me that if you store the car espcially during cold times, syou should have a full tank of gas to prevent moisture, so as the tank will be entirely covered with gas... use fuel injector cleaner to eliminate moisture and add a bit of octane, thats what they told me... it works!
