I don't think the duratecs are as good as they are made out to be. They all use oil and aren't uncommon for ring / bottom end failure. I had a 2001 tddi and it was brilliant, mate of mine has got it now. It's done 100k in our ownership and has done over 200k now. Only problem has been a broken wire in the fuel pump wiring plug but that was easily sorted by an auto electrician.
