Diesel vanagons and 1.9's don't use the rabbi type vac. pump with the
diaphragm, 
They have metal gears, sort of. 
He should look closely at the nipple (  it's a one way valve too I think )
on top of the vac pump.
They get pumped and broken very, very easily, that nipple, I can just see
the glue on it that someone tried to patch it with. - and that's the source
of he vac. assist problem.

Something else occurred to me.

I know Scott mentioned the vacuum pump. Along those lines, I recall my
old Rabbit Diesel went through a phase of burning out the little
plastic discs in the vacuum pump. I realized later that the engine was
running too hot.

Not sure if the 1.9 NA has the same or similar pump design, but.....

Did the 1.9 over heat at any time?
