Can a poor timing belt service lead to needing an engine replacement?
We have a 2005 Honda Odyssey that has been having trouble since we had the timing belt replaced last year. I complained about it running rough from the beginning but the dealership told me the trouble was unrelated. Each time we went it we spent an average of $400 replacing parts. I kept telling them it started with the timing belt replacement. It has been throwing codes, stopped running while driving a few times and has been running rough. Yesterday, I took it in because it was "dieseling". I have been bringing it in every 2-3 months since the timing service. They are now telling me I need an entire engine because the head is blown and the pistons are bent. They told me it has very low oil. The car was at 80% oil life when I brought it in yesterday and I have not seen any oil leaks in our garage or where I park. The car has 128k miles on it. I was told a rebuilt engine is $7000 or an engine of unknown history and 102k miles for $4200. It seems to me the timing belt service was done improperly. Any thoughts or suggestions?
