lifter noise
OK Here we go, my maro 2018 1SS 12k has an off and on noise at idel , mostly when hot, (full op temp) So i get all worried and then it goes away. My dealer puit the TSB in the car , that did nothing , and compaired it to a new SS and said "no diff" So now what? I hear it I dont, at idel and at 900 rpms. No engine mods, except corvett muffs.
