U20 Timing Noise

My 2000 engine was recently rebuilt (not by me) and the timing chains were 
supposedly OK.  And there was not much noise when I started driving it 
(although 
the tranny had to be redone).  Yesterday I put about 150 miles on the car and 
when I slowed down to 1000- 2500 RPM with no pressure on the engine heard a 
racket from the front end, sounded like marbles.  The noise goes away when the 
engine is revved and is not as loud when at slow idle.

Is this the famous death rattle of the U-20 timing chain?  What happens if I 
drive it to a mechanic another 30 miles?

Does the engine have to be pulled to fix it, or can it be done from the front 
after the radiator is yanked?

I have quite a fleet of roadsters, a 1600 that probably has a bad head gasket 
or head, another 1600 that is a candidate for rust bucket of the month, and a 
2000 that is becoming known as the money pit, squared!

Thanks all.
