i have an 06 wrx, bone stock with 125xxx with an spt sri. only a few days ago i noticed at idle the car makes same sort of ticking sound (and i know boxers are noisy in general) it seems to have gotten more noticable. when u lightly give it gas and up the rpms it seems as if the ticking goes with the rotations but to a certain point it smooths out and disapears. you also hear a water flowing sound from what i'm assuming is the water pump. i went to a subaru dealer by me and they said everything checks out but they didn't leakdown/compression test my car. and then 2 days after i went to subaru i hear that dreaded faux supercharger whine. i'm guessing that would be the a/c tensioner pulley? and/or alternator on its way out.? i'm just conerned that i have a bearing on it's way out or something such as a lifter problem?
