lots of oil

hi people about had enough of my seat ibiza cupra nothing but problems since i got it. i have been having boost problems since i had to change the engine. i have replaced vacum and boost hoses , airflow meter manifold sensors and still nothing improves. i have recently noticed a drop in power . so me and my mate had a look at the car in more detail and discovered that the car is burning alot of oil so we checked the boost hoses for the fmic and we found quite alot of oil in them then we had a look at the turbo and the back of the engine from the turbo to the sump including any hoses in covered in oil . i dont have a ramp so cant identify it properly . can anyone tell me what is wrong please.

not realy just going through oil very quick there is a bit of a whine when i put my foot down but not that bad

the problems ive been having are like a boost leak the car is also quite stuttery and when pulling away from a junction normally its like it wants to cut out but then its fine

had a smoke test done and it was fine

will try it tomorrow but the car smokes when pulling away from junctions and if the car is heated up sitting idleing the first rev there is a puff of smoke if you rev straight away again it doesnt smoke but if you let it idle for a min there is a puff again. it seems like the longer it idles the worse the puff is

the milage is 128000 but i replaced the engine with a rebuilt one at 118000 but as i say everything near the turbo is covered in oil and it drips off the bottom of the sump

Hi there I don't think its the engine at all due to rebuild . Sometimes when I start it from cold it has a loud whine which stops just before the revs drop . I was out in it today and was stuck in traffic and everytime I moved lots of smoke came out the back and its losing more power

Will try getting it clean and see where its coming from the reason I think its the turbo is because when I was fixing boost leaks whenever I took off a boost hose there was quite a bit of oil in them . I have a spare turbo but I am just trying to work out if it is the turbo before I fit it not wanting to spend ages changing it for nothing.
