you wont be able to see the front edge of the pulley with the covers on,
on a 16 valve engine,.
You need to remove one bolt then the right cam tower cover will come free

928S timing belt issue
Guys, here are the pics with the cover off (kinda). It looks that it fits well. The left cam pulley though stll vibrates. You can here the squeaking noise coming from there (see the video bello). I think my mechanic tightened the belt too much. Let me know what you think.

the right side belt picture looks OK.
I would replace the zip tie thats holding the green wire with another one thats more loose.
That squeak sounds like the idler bearing did it get wet? ( idler bearing is above the tensioner roller)
please remove the right belt cover and take a picture of the tensioner, also spin that bearing

if the block was not drained via the block drains prior to removing the pivot bolt for the tensioner,
This will let a gallon of coolant come out the hole and flood that bearing.

That is certainly the issue. I have asked the mechanic back them if he drained the block by the two bolts and he said that he didn’t. He removed the radiator’s bottom hose only. Do you think I’ll need to replace the roller or its bearing now?

Guys, a quick update:
The stethoscope arrived today. I tried to listen on each bearing and the squeaking comes a bit from the right cam pulley and a but string from the tensioner’s roller. I guess Stan is right and the bearing got wet and are to replace .
