Why does Honda use a timing belt for the 3.5-liter V-6 and not a chain? Other manufacturers of V-6's use chain. Is it because the engine can obtain "silky smooth power and quicker acceleration" with a belt vs. a chain? I have 256K miles on my 2006 3.5L VTECH. The cost and my time to change out every belt 100-105K miles is getting painful. My daughter's 4 cylinder Civic has a chain. Just trying to figure out the mechanical, technical advantage, or other. Thanks guys, look forward to you sharing your wisdom!
