Hi,

Any one has experienced carbon build on intake valves on DFI engine?
What did you do?
What was the cost?
Is decarbonization part of scheduled maintenance on DFI 997 and up engines?
Any ideas to avid carbonizationn of the valves and exhaust system on these engines?
Possible to check the valve with camera probe while engine still in the car?
Is it possible to remove the PVC system and EGR systems to prevent carbon buildup?

Thanks!
