hell o i have a 1996 chevy blazer v6 vortech with 130k on it. the motor is making a grinding noise when above 3000 rpm at idle. at normal idle it sounds fine. there is no hesitation when driving. also when on the highway the noise seems to get less the faster u go. i think it might be the crankshaft but dont know..can anyone help??
