Changing Motor Mounts on 1990 V8Q.

[". ." <cobram@juno.com>]

Finally got around to changing the long ago purchased motor mounts on the
1990 V8Q.  Here is a quick step by step for anyone wanting it:

Remove the bottom engine cover.  I suggest using a pair of bent vice
grips to hold the rubber vibration dampers on the engine cover when you
remove the 10mm nuts holding the cover on. 

Remove the two side air intakes on top with the same 10mm socket.

Remove the heat shields on both sides of the engine headers. (10mm
"speed" nuts-like the ones that used to hold your "Big Wheels" pedals on)

You'll have JUST barely enough room to fit a 17mm universal socket (a
regular socket with a universal on it will NOT fit) with a THIN extension
on it over the top motor mount nut through the header pipe on the right
side.  The Left side top nut can only be removed with a box end 17mm
angle wrench. (to get over the sides of the engine mount.)There isn't
enough room to get an extension through the headers on this side. 

To remove the bottom bolts on the motor mounts, loosen the 4 subframe
bolts and drop the subframe enough to fit the same 17mm universal on the
two bottom nuts.  LOTS of penetrating oil recommended, as these bolts get
tight, and they are LONG.  

Once the nuts and bolts are off the motor mounts, lift the engine up with
a jack.
The best place I've found for lifting the left side is to place a 2X4 on
the jack and lift with the top of the 2X4 on the nuts that hold the AC
compressor on.  For the right side, placing the top of the 2X4 on the
alternator bracket against the engine worked well.

Lift enough to give you clearance to remove the old engine mount and
install the new ones.  As per Audi norms, "installation is reverse of
removal."

One "gotcha" that happened to me.....
One of bottom motor mounts bolts was so corroded that I spun the
welded-pressed in nut that the bolt goes through.  Needed an extra set of
hands to hold the bolt while I turned the nut from the top.  Replaced it,
but this time I put the bolt in from the top and the nut on the
bottom....for when I do this again in ten years.

I had my digital camera all ready to take pics and put them on a web page
along with the procedure, BUT, I spent a little too much time on a
"simple" tie rod replacement on the 5KS, and I'd have to wash my hands
every time I wanted to take a picture, so time constraint is the only
reason I didn't do it.
