White smoke from My BMW 735I 2002 model automatic, what is the problem
\015 I have noticed a lots of white smoke coming out from the exhausted, not when I am driving, but only when I stop on trafic or when I reverse.\012I have changed the oil and the rest of it but still coming back, once i have started the engine no smoke at all only when car is warmed up.'\012what do you think the cause please?\012Kind regard\012Karim\015
This is most likely due to worn valve stem oil seals - this seems to be a common fault with v8 BMW's. Very expensive to fix. I was quoted today a price of $6 - 7,000 plus parts. They said the motor had to be removed from the car, and that I would be better off getting a new motor! And my car has only done 105,000 km.
I don't know much about BMW's, but white smoke...not blue...coming from the exhaust pipe...particularly once its warmed up...sounds like you've got a head gasket going out. A normal operating engine, expands and contracts a fair amount as it reaches standard operating temperature. A warn gasket may no longer expand well enough to fill the void or contract enough when cooled to continue doing its job correctly. If the smoke had a blue tint to it, I would then suspect valve seals allowing oil to seep into the cylinders. Sorry for the bad news, but I do hope this helps in some way. Best of luck!
