Okay...you fellows have made an overwhelming case to keep my EGR valve.
Bolting on the EGR valve is the easy part.
Here are my questions about finishing this EGR valve install:
1. How can I test my existing EGR valve to ensure that is it functional?
2. Is there a simpler, easier, cleaner way to plumb the vacuum lines?
I really do not want to put all that crap back on.

3. Are all thermal vacuum switches the same or do they have different ratings?
So, if a thermal vacuum switch is required, which one does the EGR valve need to function?
Where does this switch get installed? ..on the intake in front of the carb? ..on the thermostat housing?
