Hello I own a 1987 500 SEC and it smoke at exhaust system when I drive on a downing road and after nothing. It smells burnt oil and it's white (little blue) fog behind the car. Where this oil can go to exhaust system ? Do I need a new valave job ? Is it a problem of emission control system ? Maybe a problem of oil level ? Please, I need your help with this annoying problem.
The car runs very good, starts very well but I'm just have this trouble so I'm very dissapointed to see this oil go out by exhaust system.
Anyone has the same trouble ?
Anyone have an idea ?
All infos will be precious for me.

You did not mention how many miles/kilometers on the car. Given it is an 87 I would assume high miles. My thoughts would be that the valve seals need replacement. I would do a wet / dry compression test, to determine if the engine needs total rebuild. If the compression is within specifications I would consider just a seal replacement. Jim

White smoke suggests that the transmission modulator is leaking fluid through the diaphragm, into the engine, where it is being burned.
