What were your initial symptoms before long block replacement? We are going through a similar issue and wondering if this is a future recall since I am finding multiple similarities here with these engines. In our case it was engine light on reading a misfire, then overheating where first mechanic couldn't find the leak and just maxed the coolant, lost the coolant in a week and took it to ford and they found a crack in the long block....Guess there is a lot of 2.0 engine failures for Ford Edges, but at least replace the bad part you put in for free right?
