1986 Chevy Blazer V8 Four Wheel Drive Automatic 25000 miles
Fairly New sbc 350 and new turbo 400 trans. Inside k5 Blazer. Theres a slight wobble in the flywheel at an idle, which you feel when accelerating from a start. The noise started a month ago. From a cold motor, the noise starts after driving for 5 mins. Pitch of noise doesn't change from higher to lower rpm's though does fade in and out when coming to a stop. The noise is definatley coming from where the flywheel connects to the motor. I've sprayed a lubricant on this area and it changes the pitch of the grinding sound/whistle. Thankyou for your time.
have the same problem?
