Sap oozing from neighbors peach tree

neighbor has this issue. most of the tree is dying except for certain parts. should i be worried?

Okay, that sounds more ominous. There damage may or may not be from the same cause (we’d have to see photos to know). I would have the neighbor check for borers, especially if the holes are at the soil line.
