Could be the boost pipe off the turbo.

And where would the oil be coming from?

A bit of oil in the pipes after the turbo is normal but loads could mean the oil is getting past the seals in the turbo.

There isnt oil in the pipes well it wasnt anyways il have a check through week and let you no cheers

[wetwhippet]

only leaks oil when engines seen boost, can drive all over the county off boost and its dry, sees boost then it leaks..

Sounds like the turbo oil return pipe seal, got the same problem with mine, when on boost the oil will fire past the seal, and up the back of the engine.
