Hi people, I own a 2002 subie wrx sedan with 10,800 miles and had it for a year now. Its a great car and would love to learn more about the engine and what to listen for to make sure my subie stays in great shape. Some info on my subie that i modified is i put on a Apex N1 exhaust, Blitz DTT, and a Turbo XS RFL-Type H Blow off valve i think its called. Anyways i love these parts but im a bit concerned if its just breaking in or if something is wrong with my subie. For instance, my car used to idle nice and smooth and quiet,now is idle a bit rougher (and aftermarket pieces are put on correctly including proper BOV install) and if i listen closely now,there is a clicking noise which is very quiet but i never noticed it before. When i turn my radio down and listen to my suspension when going over speedbumps,sounds like they r rusted or something cuz it minor squeaks. and the one that annoys me the most is on my front driver side wheel,when i go over speed bumps and my wheel is turned,its like its banging on a bar or something,any help on this is apreciated,thank you.
