[928uk] Cambelt

[Paul R Smith via 928uk]

Is the "Porsche specialist" a 928 specialist? Do they have the correct 
tool for setting the belt tension?

The 928 belt is set tighter than most when the engine is cold as the 
tensioner backs off the tension as the engine block expands with heat, 
so it really does need to be right in the first place.

Second thing is that belts do "bed-in" and sometimes need adjusting 
after a few miles. This isn't usually necessary if the belt has been 
turned over a few times before the tension was set in the first place.

For your rear shock squeak, make sure everything is tight particularly 
the top shock mounts and the big pins that clamp the bottom of the shock.
