Question about BMW Cars & Trucks
Soon i fill the tank start excesive smoking
Posted by Anonymous on
Blue smoke coming out of the exhaust indicates that oil is getting into the piston cylinder and being burned along with the gas. This could be a leaking head gasket, worn piston rings, or the wrong weight engine oil (viscosity too low). A leak down test will be needed to diagnose.
Have you checked your engine oil level?

Volumes of white smoke is an indication of water in the exhaust. A certain amount of vapor will be present on start up, but if it is different than what has been the norm for this vehicle then a check of the cooling system is in order.

Blue smoke come from burning oil. This means that you have an oil leak somewhere that it is getting burned up and exiting the muffler. First thing I would do would be to check your engine oil level. After you are sure that it is good, I would suggest taking the vehicle to a mechanic to have them see if they can find where the leak is. Let me know if you have any other questions. Thanks for rating my response and for using FixYa!

Te blue smoke is oil getting into the piston/fire chamber..
If it is only at start-up - it is more than likely the valve seals.. Allot of the time they use plastic ones so therefor it is somewhat common for cars to do this..
If it is not to bad and stops soon after start-up,, its not really a big deal..
IF it is allot - and smokes all the time - it could be that the valve seals need to be replaced OR could be the piston rimgs are shot..
Please dont forget to rate well ;o)
