hey people i have a fiesta turbo and it is very very smokey when warming up but doesnt smoke when it is warm.

first though it was the valve stem seals and as im a trained ford mechanic i replaced them as well some of the valve guide. but to my digust that didnt solve the problem .

so i started goin down the engine road done all sorts of tests and then a friend convinced me to rebuild the engine which i did myself i relaced rings bearings i even bought a new cam kit which left a healthy hole in my pocket (it was worth it though) rebuild the head from scratch re seated all the valves and put the engine back together perfect.

this also didnt get rid of the smoke but the car goes really well the engine is sweet . so it has to be the turbo right . well im just after rebuilding that got it professionally balanced new seals the lot but now the smoke is now worse . it will only smokes on warm up and it will only happen when its at idle when its on boost its fine and it drives great and no smoke

as far as i know this should not happen. has anyone ever come across anything like this. im going mad i just feel like gettin rid the car or putting a match to it

any help would be greatly appreciated
