Has your car ever run Hot? (240+) When my 2000 S AOS failed I replaced it & it still smoked slightly, cleaned thin film of Mobil 1 from Throttle Body & intake tube & cured smoking. Later removed Intake Manifold & saw simular amount of oil inside but no smoking. Removed sec. Cats & no sign of oil there. I would think if you had oil in cats it would light the check engine light with codes. Has your car ever run Hot?
SO... does it only smoke when the temp gets to a certain level ?
It will run fine at normal temp, then i'll get on the freeway or go up a hill and it will just go crazy with white smoke...its very random and never happens at the same speed, place, rpm, or temp...it is coolant, right?
After a lot of scratching my head and staring at my baby...Im pretty sure its a cracked or warped head.
Aftermarket headers were put on it recently (will never go there again). The power steering line rubbed up against the drivers side header and eventually burned a hole-- caused a fire underneath :ah: . I was able to get most out with an extinguisher, but then hit it with water as it kept coming back...the VERY hot then cold could crack or warp a head, right?
Might want to do a compression test. I can't believe the "mechanic" hasn't done that already, as that smoke looks nothing like thick burning oil (to me, could be a camera issue too).
Draining your oil/coolant is another way to check and see if there is crossover, but on this car both things will wind up running you over $100-150 in parts & labor. A simple compression test should tell you whether or not coolant is entering the combustion chamber through a bad head gasket or cracked head (won't tell u which), and it's cheap and easy to do.
