There should be no play in the idler (or tensioner) pulley bearings.
The bearings themselves are replaceable, but you can opt to buy the complete pulley from Porsche - being a cheapskate (my father was a Yorkshireman) I replaced just the bearings in the pulley housings....
Be aware that after replacing the waterpump and belt, there is a good chance that the idler / tensioner bearings will fail due to the extra tension on them: don't ask me how I know !!
