While doing the throttle body bypass, i noticed the water pump area outlet to the throttle body had splotches of dried, green coolant.

I checked the hose and it looked fine but the coolant was a very weird pasty, green slime. Hose was attached snug as well. What could the issue? I certainly hope it's not that the outlet has a hair line crack somewhere...






Should I just use one of those Barr's Stop Leak products?

 

don't use a stop leak product. Those are VERY bad and can cause a ton of issues!

Clean it up with a bit of brake cleaner and monitor it so you can figure out where it's coming from.
