if the amount of smoke is too much the your piston rings are gone! and the valve seals also! check one thing.. drive the car for a few minutes then turn off the engine and open the engine oil filling cap! if there is smoke coming out of it (BACK Pressure) then your engine needs work, the oil will also get black and you car will reduce engine oil.. as mechanics say oil khayegi gari!
Its a 21 year old car dear it is supposed to get such problem! i have been there!
