Bit harsh boys. The water incident happened days prior, so it was not the culprit. The CAI is nothing more than a cold air intake, for the ones that don't know what that is, it's basically just a different air cleaner assembly that draws air from outside the engine compartment, not a different intake manifold, that was also not the culprit. Now the overfilling of the engine oil, that could do it... I would have thought that if Honda does not want to honour it's warranty because of the mods, then they have to prove that it was the mods that caused the engine failure. If I was you bob san I would ring the Honda wreckers as stated earlier and get a quote for supply and fit of a used engine. I'd be surprised if you couldn't pick one up for under $1500 and fitted for under $3 grand. I do agree with the fact that you would have been better off at another dealership, I know about that first hand. A good service manager would have gone into bat for you. I know of a great one if you want to know. Lastly someone mentioned a rev limiter not working during a mis shift. Thats just Bull Shit. Thats what it does. It usually cuts ignition once the pre determined revs have been reached. Good luck Bob
