Ls1 ta blowing white smoke and vibrating from engine compartment while driving

If it is blowing white smoke, and the smoke smells sweet, you most likely have a blown head gasket.

Its a lil sweet but also pungent

If your losing coolant and that white exhaust smoke smells a little sweet, You most likely have a head gasket blown, meaning coolant is dumping into one of your cylinders via cracked head/gasket and in turn making your engine misfire/run rich, burn too much fuel, Engine repair is needed. You could also check on line or the salvage yards for a used engine if repair is'nt an option.
