Thank you for your replies. The belt teeth are definitely griding.
Nothing else would sound like that. I will try the tensioning
procedure as you described and in the manual again. Hopefully I got
the tensioning hardware in place correctly. Otherwise I have to take
the whole thing apart again. I replace both tensioning wheels and both
the timing and balancer belts I got from a CNS kit on ebay. I did not
replace the water pump because I thought it would take another hour or
so. Are the CNS kit parts OK? I thing the belts were ITM but I am not
sure since the car is not in front of me right now. The car runs OK
but I hear the grinding now and then especially when the engine is
running slowly.

Thanks.
