A couple of questions

[Shea & Brigitte Rutstein <rutstein@erols.com>]

        I have an 86 5ks.  About a month or two ago I read that some of you
were getting parts at Radio Shack.  I think they were the cooling fan
resistors.  Does any one know the specs for these?  I've looked in the
Bentley and Haynes and although they are listed on the wiring diagram no
values are given.

        Also, last weekend I went about changing the antifreeze and radiator
hoses and noticed that there was a broken hose at the end of a pipe that
runs from the crankcase up to rubber connection to the intake manifold.  Is
this pipe the crankcase ventilation system?  It doesn't seem to be shown in
the manuals.  There is no PCV valve on it (and I can't find an EGR on the
engine either so I guess it doesn't need one).  The hose and pipe and the
upper rubber piece that goes to the manifold and idle stabilization valve
were totally plugged with gunk.  I eventually managed to clean it all out
and replaced the broken hose (with heater hose), but the car seems to run
about the same except the lifters seem quieter now.  Does anyone else have
experience with this hose and pipe plugging up?  I run Mobil 1 so I thought
it should be cleaner.  Of course, it could have been that way since I got
the car 5 years ago.

        Third and last question:  recently there is a high frequency
vibration through the steering wheel when driving over forty which increases
with speed.  Kind of feels like going over the road where they've ground
some of the pavement off.  It doesn't seem like wheel balance or alignment,
but could it be a cv joint going bad?  Doesn't seem any worse on turning and
is not noticeable at low speed.  

        Thanks,
