Ive got 30k miles on my motor and every once in a while it will smoke upon starting it up then it clears. The color of the smoke is white. It is my daily driver and only happens once every couple of weeks. Im thinking this could be worn valve guides or valve seals or a even a broken piston ring, or water (im not losing any though). If ya'll have any input i would appreciate it.

 

i think white smoke is water. sorry i couldnt help much.

 

Could be a bad ring
