Timing Belt Tensioning Trouble

[Aero06]

In the middle of tensioning the timing belt on my 1986 Turbo after a few months from the original change, and I'm having quite a bit more trouble with it this time around. I've finally got it back on after a bit of trouble (removed it entirely to change the front camshaft seal) but I can't get a read on the tension. Basically as I was tensioning it, the tensioner would only tension the length of belt between itself and the crankshaft, every other portion of the belt, from the water pump to the camshaft or from the camshaft to the crankshaft would be noticeably less tight. I pulled the flywheel lock off and gave the crankshaft a few rotations hoping it would even out the tension, but even now, I tensioned it to just under 40 ft/lbs according to my Krikit Tool, it seemed appropriately taught. I've cranked clockwise to the point where the mark on the camshaft gear has rotated 90 degrees, and now the length of belt that I measured between the crankshaft and the camshaft is completely slacked. I didn't have this problem before at all, has the belt been stretched out too much? I'm at a loss for what to do here, I imagine slack buildup will be less of a problem under constant rotation, but I don't want to risk damaging my valves if I'm wrong. Any advice for this? I can post pictures or videos to explain this if it can help anyone offer suggestions.

I just did mine...I used the tension tool from ArnWorx to set it. The write up in the tech notes in the last step is pretty straightforward. If you have tension on one side of the tensioning roller but not the other side make sure that when you rotate the engine couple of turns there is no drag or interference in the engine. It will obviously get harder to rotate at compression points, but should then become easier as you get past them. I did a couple of teeth past and back to make sure tension is even.
Note do not go backwards more then just a jog, 1 to 2 teeth only !

Did you remove all spark-plugs???
