My 4000 Q too has the usual "ticking" at startup.  In the winter it is
louder and lasts longer at startup.  It also appears directly related to
how full the oil is.  When I started auto-xing the car, I would shut it off
after a run.  When I started it backup for my next run, I would get the
loudest clatter ever, It would usually go away in a few minutes.  I though
I had a bad lifter.  Then I started useing 20W50 oil, and making sure the
level is FULL, and then it wasn't as bad.  Since then I have started using
5W50 syntek and it's better yet, or even nonexistant.  Anyway, if it goes
away after a bit your probably ok.  Mine now has 162k and I still haven't
replaced any lifters.

I've heard you take out the cam, and they're pretty easy to change, and not
to expensive for the parts.  Something a weekend warior should be able to
do.   ---JCG.
