So I'm tensioning my timing belt, and I have a few questions. First off, I'm using the Arnnworx 920X tool. I've already tensioned my balance shaft belts and I started with everything at TDC (using both the cam gear mark and the mark on the flywheel as seen from under the car).
First, I tensioned everything up and after cranking the engine by hand a few times, my cam gear mark is now about a half a tooth off (as seen below).

Is this normal, is it too far off? While I crank the engine over by hand, I didn't feel like anything was hitting.
Second, after cranking the engine over by hand I noticed the timing belt was sliding further and further back on the cam gear. Does this mean I've gone too tight, or is this normal.
Thanks for the help. I just don't want to proceed any further, until I'm sure everything is cool.
