is this a similiar engine to the 1.6 zetec s one? I remember a mechanic locally saying the big ends went on a car he was fixing and he wasnt able to get new bearings as ford saif the bottom end is disposable after the bearings are knackered as aparantely the shells were several different sizes and they just used differnt ones instead of machining the them all to the same size. I dunno how true this is or not so dont shout at me.

Second hand engine was the cheapest way for that car.
