I keep reading around and finding posts that say the 3mz-fe is an interference engine. However, I just got off the phone with a shop who was pretty sure it was not an interference engine. So we both looked it up at gates and it seems that the 3.3L 3mz-fe is not an interference engine. I'm not sure of any other source of information that can confirm or counter the claim by gates.
Can anyone with an even more solid source of info or first hand experience confirm this is true?
