RE: 4000Q noise after timing belt replacement

[christopher_bender@fmc.com (CHRISTOPHER BENDER)]

     I have had this same problem with mine, TWICE.  Each time it was after 
     I replaced the belt myself.  The first time I just lived with it, and 
     after many many miles, it went away, just in time for the next belt 
     change interval.  So, I changed the belt, and it is back.  It's really 
     frustrating, because I think I am being attentive to details, but what 
     is it?  I thought I had the belt too tight, so I loosened it a bit.  
     that seemed to help a little, but I am hesitant to make the belt any 
     looser.  The Bentley idea of being able to turn it 90 degrees "by 
     hand" is a little vague.  I mean, what if I am a particularly strong 
     or weak person?  They ought have a tool to do it like a 944.  But I'm 
     rambling.  Perhaps the problem is not tension related at all.  What 
     else could it be??  This could be an intriguing thread if it gets 
     rolling!  By the way, I have only used cam belts from the dealer.
