Hello Tim. The toothed timing belts won't slip so are not likely to be the cause of your noise. It's much more likely coming from the external auxiiary drive belt. Rather than slippage, it will most probably be from the tensioner pulley bearing. There are lots of discussions about this and your best fix may be a new tensioner unit. If so, they're are widely available.
