Is it worth repiping....?

Okay have a look at this install. This was installed 3 months ago by another guy, and of course he is no where to be found. The boiler is throwing an air error (351) I found a couple of leaking joints that I suspect is the culprit. Have a look at the secondary loop. They are not exactly closely spaced tees so there is no hydraulic separation and also this is the wrong type of air eliminator. What do you guys think worth repiping the secondary loop?

This guy obviously took left over parts from a super hot boiler...
