havent posted here in a while, but im in a jam. my car speaks, its not the belt, or alternator(my wallet fixed that

) , and i later found out the sound was coming from the idler pulley. makes sence, so i install the new and and guess what, squeak squeak squeak

.
thought, it is not nearly as loud as before, so is the new pulley just breaking itself in. without thinking i sprayed some WD40 on it, and it only made it louder, didin't need any more lubing i take it
could it be my belt is off track, or the pullies are dirty?
