No matter what internal combustion engine we're talking about; if the oil rings or valve seals go you get blow by - characteristic of blue smoke usually at first start up which can go away after warming up and/or under hard acceleration. Burning oil is what happens here.
Leaking oil is a whole other story. if a seal is blown you should see visible signs somewhere to indicate this; an external leak, smell of burn off on the exhaust, leakage into your anti freeze and not necessarily the other way around. I've seen cases where the ccv valve got plugged on some X5's and 46's which routed the oil into the cats. This can also happen. Most bimmers today are known for oil consumption and not uncommon to go through 2 litres per oil change maybe more depending on conditions.

Hey guys; my 2004 330Xi burns about 1L/15,000km and it has 185,000 km on it. Nothing should be burning @ 1L/1000km.

i agree with that....if i upshifted later the oil consumption definitely increased.

and that was after i changed the CCV too.

I dunno guys, it just seems like a serious problem, and a real headache of a fix, prob 2000$ atleast!

I don't think i'm down anymore to try to fix it! It def does not have a leak anywhere, it's def in the engine!

I topped the oil up, and i'm recording the mileage to see exactly how long it takes to burn 1L. I really hope its more then 1000K but i think it will be close!

Like mentioned above, it could be many things and i'm not ready to dump more money into this thing! The fact that it burns THIS much oil, annoys me, especially when i put enough cake into this thing to make it so mint. Now this.

I'm gonna look into 02 carrera 4s. We'll see how that plays out! I'll let my car go for cheaper then i wanted just to get rid of it. Engine runs so strong, i don't understand how this is a prob...

let me give you one piece of advice regardless of all the stupid bobtheoilguy articles and other so called "expert" articles you will read; DO NOT USE mobil1 ow40, the stuff shears and is way too thin, if your engine has over 120k use a BMW LL-98 approved oil such as Castrol Syntec 5w40 or what RMP uses, RS200 5W40 etc, your oil problems and "puffing" will go away......ask me how i know......

0W 40 is only thinner on start up, which means less ware and tear on the motor in the morning, and at normal running temps, 0w 40 and 5w 40 are the same viscosity. once your motor reaches 212 F both 0w40 and 5w40 have the same viscosity. oil thickens when it reaches room temp, so in fact running 0w40 would be the wiser choice to run, and maintain your motor. so how you came up with this bro science conclusion totally boggles my mind.

If anything, I used to use 5W30 Castrol Syntec... and for some strange reason, I'm liking the OW40 Mobil 1 instead.

Just yesterday the car was sitting for 2 days, i start it up and i saw white smoke for about 3 seconds.

I have the same problem. I'm losing about 1L every 1000 km. I'm going to be replacing my CCV next week (bought it 2 months ago, too lazy to change it).

I've noticed a smell of oil sometimes on my engine (especially right after I top it up). I've noticed a little oil on the side of the motor, looks like my valve cover gaskets are shot

Anyone else experience this? Try looking at your engine to see any signs of oil on the outside.

I looked on my engine and i don't notice anything.. the previous owner said he cahnged the valve cover gasket.... but this isn't the case with me. Also, depending on the severity of you're gasket leak, it will burn some oil, but not 1L per 1000Km. You're problem is like mine, internal.

Let me know if the CCV works out for you. From what i researched, it doesn't do the trick, but who knows, for you it might! Good luck!
