Check Engine Light, Runs Rough and White Smoke?

Asked by Greg Aug 23, 2015 at 05:32 PM about the 1995 BMW 5 Series 525i Sedan RWD

Question type: Maintenance & Repair

I have a 1995 BMW 525I and the Check Engine Light Just came on while I was driving, it started running very rough and lots of white smoke. I think it is the Crank Case Vent Valve/Oil Separator System. What are your thoughts? I have been researching online for a while today and if that is the problem I can not find the part any ideas?

White smoke is a indication of a blown head gasket, coolant getting into the cylinders, / Blue smoke is oil burning in the cylinders, / Black smoke is air fuel / fuel delivery system.

I have to agree with Jim, head gasket or cracked head.

white smoke is usual gaskets. too much water from exhaust gaskets too (head gaskets most likely ) BUT YOU CAN NEVER BE MISS CLEO AND PREICT UNTILL YOU INSPECT. Have a specialist diagnose your baby. Check pressure in exhaust and make sure your cat isn't clogged.

    if you let car idle for a minute or two it will stall. When you start it up again the engine light is on and runs rough, if you rev it up to red line on tac light will go out and run smooth.
