It's funny that you should mention this.  It just happened to me for the first
time last weekend.  The noise lasted for about a second, but it sounded like
a _bad_ noise.  I pulled the car out of the garage, washed it, pulled it
back into the garage, a day later I started it and heard the racket.

I always get 1/4-1/2 second of lifter noise on startup, but it's quiet by
comparison.  I use 10/40 oil changed at 2500-3000 miles.

Maybe the moral is to let the car idle for a bit longer before shutdown
on these "move it" kind of trips.
