88 k5 flywheel noise
i have a 88 blazer 5.7 tbi ,700r4 trany . i noticed some noise under the truck , sounds like its comming from the torque coverter , i pulled the inspection plate and noticed my flywheel has a wobble to it , the truck runs pretty good but lacks power , could this noise get picked up by the knock sensor and retard my timing ? also what else could be making that noise? torque converter,flywheel, trany pump ? torque converter bolts r tight , the flywheel wobbles but not the converter, any help or ideas would b helpfull thanx

Could be a warped or cracked flex plate. A noise from the flex plate could be picked up by the knock sensors.

No they're not. Also check for loose bolts and oblong holes if the bolts are loose as well as the aforementioned cracks. Had a 82 2WD truck with this problem.
