Yeah I figured I'd try this if I decide to not get the CCV changed out.
Thanks

It is very easy and recommeded

Yeah seems like it's easy enough. Just not sure if I want to bypass it yet tho.
I wish I could have seen the CCV yesterday when I was replacing the intake boot. I had it off along with the airbox, DISA, and ICV.
It must be directly under where this CCV delete goes. I missed it tho. I looked at ECSTuning for a CCV and it shows to have only three outlets.
Two of them hook to hoses (to intake and to valve cover) and the other I think goes to the dipstick hose. Appears to only have one bolt holding it on.
This is the cold weather updated and insulated version. So it may be different than others I have seen shown on here.
Honestly don't really want to pay my mechanic to change a valve and two hoses either tho. LoL

There are two bolts holding it to the intake. I don't know if it's possible to see it without a mirror. It is really up in there.

Just a suggestion, need to take a look at those hoses being used. When I did both of my e53 3.0's the hose will collapse due to so much vacuum. (as mine did) I used plastic fuel injector line and made any hose connection as short as possible. Also tried doing this setup with my son's 325xi wagon did not work, kept throwing lean trim codes. We ran the valve cover hose uphill (so the oil would run down/back into the valve cover) then into the air filter box and capped off the manifold vacuum. One more thing I forgot to mention, the clearance between the engine and hood e46 you will have to use close elbow's to be able to shut the hood. Just remember when it leaves the valve cover it has to go uphill immediately so that gravity will pull the heavy oil droplets back to the valve cover. If you run it straight to the vacuum ports you are defeating the purpose of this bypass.

quick update for me, did mine in feb, changed oil, getting ready to change oil again, and oil level hasn't moved a drop on the stick....zero issues....

Great thread. I just bypassed my CCV a few days ago, sticking to the instruction of the initial post. Everything went fine. The only thing is: I'm getting a strong smell of burnt oil inside the car once in a while. Not always, just after high revs. Smells like someone was grilling chicken inside the car.
It's an E46 320i convertible, M54 engine.

Here's a quick video I made showing a bad CCV for diagnosis, check it out. Functioning CCV should have no strong suction like you see in the video. Defective valve and or blocked dip stick tube can create excess pressure like shown here:

That's the potential downside when the CCV is removed. and when the engine RPM returns to an idle after reving one of the highest likely circumstances to generate your symptom. FYI- I think if stop grilling chicken with burning motor oil it will taste much better.

Just did this today as I got low idle cause of broken plastic hoses if ccv valve so that's easier than ccv valve and easier to replace and if I get better mileage and get rid of carbon on my exhaust it'll be better yes
