So lately my car has develeped a strange grinding/ buzzing noise coming from the pulley/timing chain area. The car is an 01 z24 with the m45 sc, and I would hear a very faint version of this noise every so often after a rain or something but now it is much louder and is all the time. It is kind of a grinding sound when I give it throttle and is sometimes worse than others, then when Iet off the throttle its kind of a buzzing sound. Im pretty sure its coming from the pulley area, or the timing chain area but its more in front of that. Other than noise the car still runs fine, and still boosts fine as well. Does this sound like a timing/ valvetrain problem or maybe something along the pulley system? Anyone ever had any problems in the sc snout of the m45?The engine oil and level is fine as well. Any info is greatly appreciated!!
Dont mind my head in the end lol, just putting my ear to the sc.
