I got my car back from Darkside performance last night after peppering drew with a thousand questions. I had to drive it to Lakeland, it made it there with flying colors . But about 30 min of driving in the city I start to hear a odd noise in the engine bay. Its comming from either the timing gear/power steering pulley. Its something that I have never heard before working at Nissan for 2+years... 'rub RuB RUB, rattle' it gets progressivly louder, and rattles like a rattle snake. At idle theres 10-15 sec between the noise. I'm going out there now, but anyone have an idea? The car runs great, no issues.
