up hill or on the level - it must always drain down!  What you will have to
do is drill a hole in your aluminium oil pan and visit a hydraulic shop to
get those nifty compression fittings and a new return line to this fitting
and the turbo so the turbo drains straight into the pan - last one we did
cost us about $45 CAD for the parts. >>

While I agree with this, it is important to note that the best information I
have suggests that the oil entry point must be above the oil sump level. Even
though it seems that VW enters the pan below the oil static level, my
information says this leads to turbo bearing replacement at frequent
intervals. On my system I am using a mini sump and a scavenge pump to
properly clear the line.
