Hey Scotty, So I have been reading a lot of conflicting information on whether the Toyota JZ engine series is interference or not. I found this video (not me) Testing this out. Maybe you could shine some light on this subject. It's frustrating because I have an 05 GS300 with the 2jz-ge straight six and there is a lot of conflicting information. As far as I know one of the only interference timing belt engines toyota has made in recent times is the 3MZ-FE in the 04-06 Lexus es330.
