Good engines, not had one issue with mine!
I Have to say, I disagree about the oil usage, I don't have that issue!
Just make sure (Although it's a given it should have been done) that the cambelt has been changed, Fords recommendation is 100K, or 10 years, whichever comes soonest, but you would actually always change before both of these figures.
This is an expensive job, as it's labour intensive, so even if you do yourself, it's still a lengthy job.
