[stuff I agree with snipped]

A dim and distant alarm bell is ringing on the oil cooler lines.  On
ur-quattros, they have different fittings in single and twin filter
applications.

At least, this is based on a sample of two - John Coughtrie's WR on
the stands in my garage, with both of us underneath it and me saying:
"Coo!  It's different to my MB!"

As indeed it proved.  Steve _might_ need to use an oil cooler off a
twin-filter car, or get lines fabricated by a competent hydraulic
hose shop - of which there seem to be many about.  Find a large parking
lot full of earth-moving gear and ask sweetly.
