Ford 8N dribbling coolant out of radiator overflow, not overfilled.

I’ve added to some of my older rolling stock with good results…

I think I’ll stick with the 180* one then. This is very much a “weekend warrior” tractor, not an everyday working machine. I have a new radiator cap on order- I’m in the process of restoring this tractor and wanted a replacement cap with the hood ornament… Will update you guys when it arrives.

In the meantime, what are these little ports on both the intake piping and valve inspection port? I’ve attached a picture below. Looks like they had a line attaching them at one point. I’ve since plugged both the ports to prevent contaminants from getting in. It certainly isn’t factory, and I couldn’t find any reference to it in the FO4 manual either.
Thanks again for all the help guys. It’s my first 8N, always wanted one and now I’ve got it!
