thats my next step, that and cleaning it. this pulley was grinding when rolled by hand. and i could feel it when running if i touched the bolt. the rest are smooth feeling still, so it could be the belt. or one of them.
now it seems to be coming from the sc idlers, one of them. being they are the last 2 that are not new, one was swapped with a used one, so it could be on its way out too. all i know is 2 more and they are all new.
at least it dont feel like its gonna snap a belt. lost belt on these cars never adds up to any thing good it seems.
