Power seems inconsistent. On long grades where I am running
at 70MPH or so, the car slows down to 60. I have to force a
downshift to keep roadspeed up to a reasonable level.

In addition on a short upgrade (starting from stop), I seem to
have no power; no real pull.

In addition, there was some oil seepage at the crossover and
the intake manifold, indicating some blowby or that the turbo
seals were leaking. It is possible that my mechanic ovefilled the
oil a little during the oil change just before I left for the trip.

I checked the turbo. There is virtually no play in the shaft and
it spins freely without any catching, etc. so I am not sure that
it is the turbo anymore.

When I was looking at the turbo, I noticed that the vacuum
line to the EGR valve wasn't down all the way on a connector
to another hose. In any case, it is fairly easy to slide in and
out.

I am looking for a pump to do some vacuum tests which is next
in the plan.

On the opposite side of the engine near the firewall there is
a sensor where a number of vacuum lines connect, including
one coming off the intake manifold. Does anyone know how
to test it?

Thanks,
-Ralph
