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  |
The chain guide block at bank 1-3 vs 4-6 moves the opposite directions. Perhaps the 1-3 pads (the chain guide block moves down at 1500 rpm) are exposed to more friction at the changovers. Another possibility is that one side gets more lubrication from the chain than the other. The two banks differ in many ways actually.
