I've got an '07 1800 petrol Ghia, nice car but the previous owners were unaware that engines need oil to function and now the bottom end knocks a touch. I thought about rebuiling the bottom end but Autodata doesn't give any torque settings, only a note to say leave it well alone!

Next option was another engine but I'm not sure exactly what to look for. Mine has a QQDB code but do i need the same code, or will any Focus / Cmax Duratec do? Apparently a Mondeo one won't go but no one really seems to know why!

Any help would be fantastic :)

easiest method is to replace like for like most mondeo engines wont work as they are ti vct units not standard petrols any 1.8 engine will fit from the zetec e cars

Zetec? This has a chain drive Duratec in it. Speaking to our friendly parts people a couple of days ago he plugged the reg in and the engine part no. That came up was '07-'10 Cmax and Focus and not just '05 on Focus. It's the 125 not the 120 and some things like the timing were tweaked. So while I reckon I could fit any Focus Duratec potentially it might not run 100% or there could be emissions issues. I'm thinking it might be rebuild time tho a short motor wasn't as expensive as I thought and that was retail, I'm now waiting to hear the trade price.
