i have a 08 gt with just 2000 miles on it, sence ive got it. the car smokes every time i start it up.as far as i know thats the only time it does have you heard of anyone elses car doing this ford says theres no heat sink. what there the hell that is. i do know cars and motors built a few but never heard of that my guess with out doing some checking my self because of warrenty is leaky seals or weak rings until it heats up .what do you think.
