It may just need some run time after the PCV replacement, a nice long journey once you've sorted the boost issue, and another oil change for good measure. But...and there is a but...if the garage have neglected to properly clear the lower port which returns the oil from the catchcan back into the sump you may issues down the line. To understand what I mean have a read through the following threads

I've done the glove thing and it still puffs up a little which is annoying, hence me posting. The had a good 2 hour run back from being collected from where we bought it from but it seems as though nothings been done, I could be wrong of course. Great links there and work from
CNGBiFuel too.
I need to suss out my boost issue which really is a pain in the ar$e and could have a vacuum related issue. There seems to be so many bloody vacuum lines on the 850 its a maze of potential problems. Is there a full vacuum diagram anywhere showing all the various lines and connections other than the usual turbo to turbo control valve red/yellow/blue layouts?
Many thank
