Hey guys, I'm a new lexus owner (lexus is250) so please go easy on me. My car has been burning oil heavily. Its also got white smoke coming out the back. I've been told it may be the pistom rings and that it's gonna be a costly repair. Can anyone recommend someone and tell me how much it'll cost exactly. The symptoms that my car has are as follows: White smoke out the rear (none of it blue) Burning oil It pulls fine No misfire Engine runs smooth Just worried that it may be a catastrophic faliure
