More questions to 4kQ owners

[Charles.DePenning@frco.com]

     A big thank you to all of the people who responded to my questions
     last week regarding my new project 84 4kq- Bill, Phil, Todd, Stott,
     Dan, Steve, dave, Huw.  Of course a weekend full of car-type
     activities raises more questions:

     1) Can anyone confirm/deny that the part numbers shown in Huw's web
     page (http://www.thebook.com/human-speakers/audi-gearshift.htm) for
     the bushings etc. also apply to an '84 4kq?  I'd like to get the parts
     ordered soon-driving the thing is an exercise in futility.  Huw- your
     website is a blessing we keepers of the early-eighties flame!  Kudos!

     2)I replaced rubber bits in the diff lock circuit.  I'm still not
     getting any actuation of either center or rear solenoids.  Do the
     linkages freeze up over time?  I'm very leery of the cable that
     connects the center solenoid to the differential.  Any BTDT's?  My
     test setup is an old refrigerator compressor that is verified to
     pulling 30" Hg, connected to the white vac supply line under the hood.
      I am hearing hissing air (small amt) around the lock switch,
     especially when closed.  Are these switches usually pretty sturdy, or
     are they a failure point?

     3) Thanks to those who recommended getting an oversized thread drain
     plug to repair my stripped pan.  It seems to be working- no more Exxon
     Valdez.  I got the 1x oversize- the 2x oversize was not available at
     my shop.

     4)Does the center diff share fill plugs with the transmission?  I
     located a drain plug on both the diff and the trans, but only one fill
     plug on the trans.  And the capacity-  is it the standard 'fill it
     till it drips' method, or is it more?  I plan on using Redline MTL in
     the transmission, any recommendations for the diffs?


     I must say, I am having a blast working on this car, and my wife is
     beginning to regret the purchase.  "Yes but honey, now you can have
     the turbo!"

     TIA,
