Question about BMW 750i
Posted by Anonymous on
If its a water vapor it might be cylinder head gasket or a crack on the cylinder head, if its an oil vapor it might be piston rings or valve guide seal or valve guide broken due to drive while cold.

White smoke means engine coolant is entering the engines cylinder's . Which could be a bad head gasket , cracked head or block , or intake manifold gaskets ! I wouldn't drive it like this you could damage the engine more !

I had the same problem with my '87 Buick LeSabre 2 years ago. But it didn't seem to fit right, the car was running fine up until it just didn't. I had 3 professional mechanics swear it was a blown head gasket. I researched thoroughly and found out this particular engine make has a DEFECTIVE upper intake manifold which can break down and cause coolant to leak into oil, simulating a blown head gasket. The NHTSA had issued a recal on SEVERAL GM cars with this engine, EXCEPT for the '97. I filed a complaint with the ODI and as of today it is now COVERED as a "Defect & Recall". NHTSA ID number 96V116000. This MAY be your problem if it is NOT the "usual" blown head gasket. Hope this helps.

if the white smoke is in the morning,only then it is valve seals and if it is through out the day as your driving the vehicle then the engine need over houling,(rings metal and main bearing in the engine need to be relace,including valve seal , top gasket,botom gasket and oil seal for proper perfomance.
