Well, I guess a lifter will be easier and cheaper than a valve to fix.  So, um,
since the Bentley is at home and I can't remember, are the lifters pretty easy
to get to?  I know how to tear down a small block Chevy, but not an Audi - are
the rocker arms mounted right over the lifters like in my 350?  All I have to
do in the Chevy is pop off the valve cover, a single nut holds down the rocker
arm, and out comes the lifter.  Same deal on the Audi?  Na, can't be, that
would be too easy...  Thanks much for the heads up!  BTW, is it safe to drive
the car with a screwed lifter?  It's still sitting at home with bad shock
mounts, so I won't be driving it until next week anyway, but is it safe to
drive for a while until I fix the lifter?  Or should I just let the thing sit
for another year or two until I can afford to fix it?  I still have the '84 (my
girlfriend is real happy about that too!) so I can let the thing go a little
while longer, but the Quattro is definately more fun to drive than the 5kS!
