The Service Manager didn't let me read the whole Service Letter, so I couldn't say whether there was an extended warranty or it was a problem area.

My idea is to write Honda America stating that if they knew about the problem in 1998 on the Accord V6, and the Odyssey shares the same block and EGR system then why didn't they release a letter for the Odyssey? The other thing that bothered me was that the Service Manager told me that the kit they used to upgrade the system was the same used on the Accord.

Do you think I am wasting my time to write Honda?
