That lower idler is toast. I also see lots of crap/sand in the timing belt area. I'd look at replacing the seals that are around the covers, both the rubber ones and the foam ones behind the inner covers.
Also, how's the oil pressure? Just thinking that because you're right there, you might as well replace that too?? Oil pumps are fairly cheap off ebay and could extend your engine life
