The first time I ever heard this sound I had my 1990 Carat in New York
to visit my daughter and to bring a bunch of furniture into town for a
friend who had bought an apartment there. We were going to be there a
week before the friend showed up, so the car sat in the underground
lot at washington square village so the nice furniture would not get
ripped off with the car sitting on the street. When time came to pick
up the car, I was horrified to hear it coming up the ramp. I thought
the attendant had done something insane to the engine. I immediately
began worrying about how I was going to get the furniture delivered
all the way up to the the eighties, and then the thousand miles home.

By the time I got the furniture delivered, the clatter had gone away.
I cannot tell you how happy I was not to hear it. After that, it would
happen after sitting for a couple of days but Marvel Mystery Oil
seemed to help.
