proper clearance for the power valves are 2-3.5mm without the gasket. don't know about the feeler gauge.

what happens when they are out of adjustment?

Dont they auto adjust?

 

[gonesleddin]

dont over tighten the cables, the cam will keep turning and pull through the valves....big $$$,

No auto-adujst, they are control cable controlled by a servo motor. Out of adjustment can open the valves too soon or too late. This kills power, and mileage. Yes, too tight can pull the ends out of the valves.
