Ok...all hoses & nuts removed as well as the tach cable. After days of saturating with PB Blaster penetrant and tapping, the best I can gently pry apart is all but around where the tach cable housing is. Am I missing something? Do I need to remove the tach 'connection' out of the housing in the water pump. I'm not familiar with this, so all I did was disconnect the cable...Maybe some more patient soaking with penetrating oil?
