Look for a 1.4 from a Fiesta, Fusion, Puma or Focus.
These engines commonly burn oil through their valve stems, but your engine sounds seriously nackered.
Try get a low mileage engine. When you get your new engine be gentle to it when it's cold and change the oil every 6 months or 6k.

My 1.6 Focus is on 85,000 miles and was owned by my Mum whos a district nurse since it was new (2003) and I had it off her a year ago. Always had yearly oil changes until I had it and my Mum never thrashed it. Does use a little oil (litre every 2000miles?) but it's getting better the more I change the oil?

My GF has a 1.25, 40,000 miles and when she had it it had yearly oil changes. My GF has no mechanical sympathy and has been thrashing it from cold. 2,000 miles later and the top ends tapping like hell. Sounds like a diesel!

These engines love fresh oil, kept under 2,000rpm when cold (2,500rpm up hill say) and a good blast now and again when they're hot.
