Скачать или смотреть Volvo s60 t5 smoke from exhaust, burning oil, turbo? Valve stem seals?

Hi all, after a bit of advice please! Sorry vids are a bit long for whats in them, werent taken for youtube initially!

Car is burning about 1 litre of oil per 800-1000 miles, no leaks, performance is good, cant see any smoke while driving or stationary only in video. Seems to smoke when revs drop after rev. PCV was cleaned including sump off by an independant volvo garage about 5 months ago and seems to have good vacuum at dipstick and oil filler hole.

This vid was taken after a 6 mile drive, fully warm on the guage and left idling for about 15 mins (while cleaning the air con), I will upload another video with a rev from cold start sitting over night (much the same)
There is some oil in the turbo charge pipe but nothing that excessive and dripping slightly from the pipe from intercooler to ETM but nothing on the ground. NO coolant being used in 10,000 miles (since purchase) guessing most the white smoke is water from fuel etc. It reduced after going for a drive round the block.

Had it in a couple of times and the garage seem to not be able to find much.

Thanks anyone! Any ideas would be great
