Timing Chain!?
#2
The chain or the cams? If the cams are off one tooth, then just remove the cam and reinstall it one tooth over. If the chain itself needs to be adjusted, you have to remove the TCT to take tension off the chain and then remove the cam wheel bolt carefully without dropping anything. Might as well remove the cams to align everything perfectly. To be honest though, you should be fine as long as you have piston 1 at TDC and the cam marks aligned. Mechanically I can't see the need for the cam wheel itself to be aligned in time with the cams. As long as the cam marks align with piston 1 at TDC you should be good because there is no cam wheel angle sensor.
Remember to torque the cam caps properly after you remove them, if you mess those up you'll be in a world of pain. They are a matched set and cannot be individually replaced, you'll need a new head. The manual says to remove all tension from the valve clearance jam nuts so you don't have to fight the valve springs while you reinstall the cams.
