I think that I may have a problem with the one on my motor. It may be loose, bc i just noticed that my belt flaps a bit when I give it gas. Is it a possibility that its worn out or maybe just kinked? This is a new motor as my last z6 died on me so I have another, should I have to switch out. Any ideas on what could be wrong and an easy fix? As I dont want to spend 40 bucks on a whole new tensioner.

 

Tension Adjustment

CAUTION: Always adjust timing belt tension with the engine cold. NOTE:

• The tensioner is spring-loaded to apply proper tension to the belt automatically after making the following adjustment.
• Always rotate the crankshaft counterclockwise when viewed from the pulley side. Rotating clockwise may result in improper adjustment of the belt tension.

1. Remove the cylinder head cover.
2. Remove the upper cover.
3. Set the No.1 piston at TDC.
4. Loosen the adjusting bolt 180 degrees.
5. Rotate the crankshaft counterclockwise 3-teeth on the camshaft pulley to create tension on the timing belt.
6. Make sure the timing belt and the camshaft pulley are engaged securely.
7. Torque the adjusting bolt to 45 Nm (4.5 kg-m, 33 lb-ft).
8. After adjusting, retorque the crankshaft pulley bolt to specified torque.

Specified Torque: 185 Nm (18.5 kg-m, 134 lb-ft)

So does the bottom cover need to be off to reach the tensioner? Because if not, this will be very easy to try.
