Jac Mac - the early version 1UZ's w/o VVTi drove the exhaust cam from the intake, midway down the cams, however the VVTi motors moved the mechanism forward, so it's just behind the intake gear.

By doing this, and using a clever hollow, splined shaft arrangement, they keep the exhaust cam timing static, while being able to vary the intake timing. It's stuff like this that keeps me in awe of Toyota's engineering and their motors.

On the starter motor, yes it's located in the Vee and a bear to get to, but fortunately failures are very rare.
