I installed all 3 new tensioners in my 2001 earlier this year, though because the car was built in Feb 2001, I think the engine would have been assembled late 2000 and then transported to Finland for co-assembly to the chassis. It has the dual row IMS bearing & later style toothed "Hi-Vo" type chains fitted, as my engine is #67 1 07779.
The start up rattle from cold has always been with the car, especially after sitting for several days, and sometimes even when hot after sitting for a couple of hours after a run. But since the new tensioners were fitted, the rattle has reduced significantly (~50%) from cold and has ceased completely from hot. Which one of the tensioner(s) was responsible for the rattle is difficult to tell, but I'm pleased I replaced all of them - when one bleeds down, the others will surely follow.
