As for the deviation: in my 99 986 base the chain pad at bank 4-6 was worn down to the ground and fell off. Bank 1-3 was not that bad. So it looks like an exception, I know nothing about the deviation values before the rebuild though.

Yup it was something that my brain locked on.
seems most issues are with bank 1
Another interesting thing is that 986's for the ROW market only report Camshaft Deviation values on bank 1. Or so I have read.
So why does bank 1 seem to have more issues that bank 2 in relation to Cam timing (Vario Cam timing components)issues??? Engine rotation direction creating certain wear patterns???? That's the only thing I have come up with so far. But it is just a WAG
