Where's my oil going?

[Siggy]

Thanks, I'll try the google thing, plus I found the right posts mentioned up above so I should be good. I knew it was something to do with Crankcase Ventilation but couldn't figure out the first C Thanks for that.

I'm debating between doing the mod and just putting a new Oil Separator on it. Will putting the new oil separator on it resolve most of the issue or do I really need the mod to resolve it to a higher degree?

You don't need the mod. If your CCV is functioning correctly you shouldn't see more that a quart per thousand miles which is not unusual for the M54. My experience. Others claim much better. The mod looks like "redneck" plumbing to me. But, that's just me.

- I did the stock CCV using BMW parts, cost was about US $150.
What a waste of money, oil consumption was still 1 qt/300 miles.
I wrote the CCV detail below.
Looking back, I should have done the CCV Mod from the get-go!

In fact, when I bought another BMW (2004 X3 2.5i), I went straight to the CCV Mod, no regret!



- My CCV Mod is in thread # 164:

So, don't waste the money on stock CCV parts, save the money for beer!
