I have a 2006MT 350z it has 178,000 miles. Car starts perfectly no problems and runs with no problem. But I have a few annoying *** sounds when I press the gas pedal I here whirring I can even hear it a little when it’s in neutral. I tried to listen with a long screw driver, both idler pulleys are totally shot. I also touched my PCV valve is also making a buzzing sound and vibrating in pulses. I’ve also seen a few threads about the tick sound I believe it could be my injectors I’m sure it’s not piston tap. If it was I've already got forged pistons and new rings ready togo in.
