4000q maintenance

[CJMiller@eworld.com]

I have a '86 4000 cs q that's overdue for maintenance:  125,000 mi, time to
replace the timing belt, water pump, and power steering/alternator/ac belts.
 Any other suggestions on work to complete at the same time (economies of
labor...)?  How much labor would be typical at a garage?  I bought the water
pump and belts at GPR some time ago...

Also, I have a new clacking sound that sounds similar to hydraulic valves
(but not same, louder) that seems to be my aux. vaccuum pump that's driven
off the camshaft.  How do I check/repair this?  I've heard they fill with
oil; will draining it be enough?  How do I do this?

Any advice appreciated... Is it worth doing this myself?
