I thought if you pushed a car over 3 or 4K and was accelerating very quickly then this would normally happen.

Your problem seems to be what you suggest turbo pipe work on my 2.0 tdci had a similar problem new turbo pipes not replaced by previous owner loads of black smoke these pipes have what i can only describe as a sump where it fits on the induction side of the turbo and will fill with oil when turbo blows almost impossible i,d say to clean it out completly hence residue being sucked into turbo blowing out in plooms of black smoke only sussed this out after turbo failure on replacement engine and hence the reason ford say if turbo goes replace all the pipe work .
