Sounds like it's pretty serious. Blue smoke is usually indicative of burning oil.
Hopefully it's your valve-stem oil seals as this is just a case of removing the head and having it refurbished.
If it isn't that it will more than likely be worn piston rings. This is the more serious option as it is possibly an engine out (depending on access) and internal rebuild and replacement. Both of the above options are expensive only because of the labour involved in replacing the parts.
Try to do as much as possible yourself to minimise expenditure.

The problem with this car is one of two things, if it is not running extremely bad it is more than likely a valve seal leaking oil into the cylinders. The other problem would cause the vehicle to run rough and possibly shake a little, and that would be a bad piston rings on one or more of the cylinders. Both are a little costly, but the rings are far more expensive due to the engine having to be completely torn apart to fix.

Blue smoke is usually bad rings. But in the meantime, try changing your oil, see if that helps.

My 325i is smoking alot


Depending on what color it is, you could have to much fuel, or a coolant leak, or oil in your engine.


Blue typically means Oil
White usually means coolant
black smoke usuall means fuel.

My car is smoking blue smoke


Blue smoke out of the exhaust is indicative of either worn piston rings or valve guides. Either of which will require extensive work to fix. Oil is basically slipping past the rings or guides and into the combustion chamber, where it is being burned and expelled as blue smoke out of the exhaust.

Keep an eye on your oil consumption. A newer model BMW like yours should be consuming less than half a quart of oil every 3-5k miles. If it is consuming more than this then it needs to be diagnosed as either the piston rings or valve guides and repaired, typically by a shop for a job this big on a late model BMW.

Starting using oil abt 125K miles, abt 1 qt per 1200 mi. Dealer recommended repl PCV valve and hoses which we did. Repair had no effect and car now using abt 1 qt every 800 miles. No leaks detected.


is the car smoking blue or is the oil leeking out ?

if the is consuming oil by buring it while driving the faults are either :

Valve seats / Burnt valves
Piston Rings
or sump compression which can force oil into the combustion chamber causing it to burn it and expel the burnt oil via the exhaust system.

Either way, its going to pretty expensive on a 2002 5 series.

2003 F150 4.6 w/ 90K miles using a quart of oil every 3 weeks. what's most likely cause?


A V8 engine will start to consume more oil as they get more and more
miles on them. The valve stem seals and piston rings wear, and let
more and more oil burn off in the exhaust. How many miles are you
travelling in said 3 weeks?
