Rob,, Before even doing a prebuy, I would get the details on the engine overhaul and forward that to an MOT aviation engineer here in Canada, He will advise if the engine overhaul meets our specs. If it does, then it should be good to import,, Then and only then would I spend money to do a prebuy,, If they don't accept the overhaul,, well time to say goodbye to the plane,, regardless of look or condition. That is, unless you still want it,, but more then likely to get it imported you'd have to have the engine O/H here or in the US by an approved facility.
