^ there you go. game set, match.
Now I don't feel so bad for having done a flush figuring 10 years was way too long for that to be sitting pretty, and despite reading somewhere that these flushes were unecessary in the 986/996.
I got another 20-25K miles out of the pump after that flush and the blades were intact when the unit itself finally let go at 85K miles.
