Hi,
Is it a T5? If it is100% sure that will be the turbo seals.
You could try a thicker oil to slow down the leak through the turbo, but that will only be a temporary fix, you'll need a turbo re-build.
If it's isn't a T5, it's bound to be a vacuum leak somewhere try the filler cap and dipstick seals, these need to be completely sealed to form a vacuum otherwise they breathe! Need a complete seal


Let me know how you get on hope this helps!
