Just picked up a new one, 93, teal ?.. ls. Yeah so, It is making a knocking noise.. while its on.. idle or not. Clutch is 3 days old, timing belt is 4 days old.. Its a bit of a clicking/knocking/clunking.. not very loud, but can be heard when in and out of car.. any ideas what this could be ? cause it sure would suck to have a new crap car.
