Pulled my heat exchanger and sure enough it had a crack in it. Fortunately the shop I took it to was able to repair.....
Now the question is why did it crack? Did the shop offer up any explanation for the crack? Where was the crack? If it was one of the tubes, and the crack bulged outward, that's a pretty tell tale sign that it wasn't winterized properly.
