I have a 01 "S" , upon hard acceleration, usually in second gear over 6000 rpm I get a huge cloud of white smoke from my exhaust. No warning lights or engine running hot. I can continue driving without any additional smoke. 2 months ago I had my Air/oil separator replaced, so by now any oil residue should have been burned off. I have no smoke on start up, the engine runs very smooth without any strange noises. Also motor is not running hot. It seems very strange, any advise ?
