hey i have a small blowing noise or it sounds like a blowing noise from the left side of the engine near the aux belt and pullys, it doesnt make the sound all of the time and sometimes it doesnt make it at all. under my induction kits there is a small black sensor that has a pipe through it, and joins to the breather pipe i think, this makes a ticking noise with the other noise?? can anyone help ?? cheers chris
