Alright, here we go. Against my better (joke) judgment being tired, sick, suffering from allergies and way behind on my prep for tomorrow's DE, I went and cut some valves.
The 3.2 valve #930 105 419 08 is shown here with dimple and a solid stem!
Here is the 3.6 valve #964 105 419 00 showing dimple and solid stem!
Here they are side by side.
Interesting, want anything else cut up?? I am feeling brave!
Guess this means not all "dimpled" valves are NA cooled! Soooo
maybe the parts books are right after all!
Cheers, Jeff
