The reason I took the alternator off was to look at the cooling tube in there. I didn't have the kind I saw on a uTube video, and I didn't see any leaks, although I couldn't remove the insulation shroud to see it very well. The big (cracked) plastic thing is the insulation shroud, supposedly to isolate the knock sensor from external noises (that's what a uTube video said anyway). It's crumbling away. I'm not worried about the white crud, just wondering if that's what happens to old dried up coolant, or what else could produce it. I'll have to look into getting a pressure tester.
