Hi guys (I have a 2.0 Zetec Vin 3), and have a similar situation. I just recently did my timing belt with the help of a friend. I just finished putting everything back together this morning. Everything tight to torque spec...
The engine started on first try, but when I was giving everything one last inspection before the test drive, i noticed that the tensioner tension "wrench" marker was fluctuating back and forth and not staying to the correct tension that I had set similar to what its shown in this video (http://www.youtube.com/watch?v=_2t2q_PCjVI
The engine actually runs really smooth and there are no noises coming from the tensioner. The car actually runs smoother than it did, Just was wondering if its something normal.
