Look in the line from the vac shutoff -- if there is oil in there,
replace the servo and clean the oil out (else it will eat the valve on
the steering column). The servo diaphram is holed.
You also probably have leaking lines for the shutoff -- brown line from
main vac line to switch, brown with blue stripe to the servo. Check
for obstructions at the main line connector, it has a SMALL hole and
tends to plug. Do not drill it out, please, as this will cause other
problems.

Okay. boys...this vacuum pump deal is getting odd.
All the other failures I've ever experienced has had oil spewing into
the
air cleaner housing. This failure is different.
The car will not shut off (I've checked the shutoff valve SAT...it
holds
vacuum like mad). There is NO oil getting into the air cleaner
housing. The
cruise still works. The HVAC is no wierder than usual. But there seems
to be
oil getting into the vacuum lines where oil hasn't been before.
When the main check valves in the vacuum pump fail, what happens?
Any ideas.
