When I did this procedure I used a different PCV valve and it did not work correctly. Got the correct one and all is fine. Gave my e39 to my son over a year ago. Practically no oil consumption. The car has over 175,000 miles with regular maintenance service.

Finally did the CCV delete
After resisting for years and going through quarts of oil, I finally got around to doing the mod posted here by BavarianE39. Thanks for the excellent detailed instructions.

I'm not sure how to adjust the size of the image here.

That looks real good. On mine I have the pvc valve tilted up slightly maybe 25 degrees, to let gravity help with the valve. Mine works like a charm. Great write up as noted.

951 miles since doing the ccv replacement and it seems there's no oil consumption so far. I'll post again when I've got more miles on it.

I've shared this ingenious repair to a couple of BMW drivers.

I did this mod and it works great, zero oil consumption, so no complaints.

Question re decommissioned system...

1. I leave the Oil Trap alone b/c it is not sucking any oil or any air (I blocked the end of the hose where it joins the valve cover).
So is it OK to leave the Oil Trap in there "forever"?

2. The Return Hose ---> Dipstick Housing, this hose can break with time but since the Oil Trap is decommissioned, is there any harm of ignoring this hose? Let's say it is broken but you ignore it, any issues?

Status Update
I've got 2,228 miles on the car after the CVV removal and it looks like the oil's down about a 1/4qt.

I still haven't replaced the valve cover gasket which I suspect has a leak. I don't see any oil on the ground yet but I do smell burning oil in the cabin after long periods of highway speeds at about 70mph (after exiting the highway or slowing in traffic). That could be a contributor to the 1/4qt drop. Either way it's a huge improvement over what it was before removing the CVV.
