I have a 2006 odyssey with about 163000 miles on it. I had it tuned up at about 140k miles and there was oil on one of the spark plugs. It also got a new torque converter at 65k miles and now I am feeling some symptoms of impending transmission problems. It's eating a little oil but not much. But on the whole, it is still running very good. Is it time to trade or sell? It's the model right under the touring model so it has nav, DVD, leather. I am fairly good on maintenance and very very good on oil changes.
