Engine Oil Leaking problems of the 2000 Honda CR-V

At approx 147,000 miles, check engine light came one. After determining it was not due to leaking gas cap, ran a diagnostic on it. It produced error codes of p0300, p0301, p0302, p0303, p0304 and p1399 (all misfire codes). Took it to a highly recommended mechanic where they also ran their own diagnostic with same error codes. The checked the valves right away because there is a known issue (defect) with the first gen crv head. Honda has admitted the problem and re-designed the head for my year model to eliminate the value problem. My heads had already been adjusted at 95k (as recommended by the Honda dealer service dept) although the recommended adjustment is at 105k miles. With mine requiring adjustment 10k miles sooner, this should be a red flag of a problem with my engine. But now there is no room for further adjustment; only solution is to replace the head with the re-designed head. In earlier years (2006) Honda was replacing at no cost through their goodwill program. They won't assist me in any way - in fact, american Honda customer service told me there was no such thing as a Honda goodwill program. I found out about the program because my dealership told me about it and that american Honda and denied my request! I had every single required maintenance service performed at our local Honda dealership; on time or early as recommended. The only time it was ever taken somewhere else was for a few oil changes and that was only because Honda couldn't work me in according to my work schedule. The reason I purchased a Honda in first place was because we were told that any Honda that was maintained per the recommended service manual should last 300-400k miles. I didn't even get half of that! never again - no more Honda's for me.
