---> Corteco $19: I would trust Corteco, a very reputable company, major supplier for MB, BMW etc.
---> I'd not touch Elring, Victor Rein etc.

It is NOT worth the time redoing the job 2-3 times.

Thanks, I will try Corteco next; the Elring is already here (and I read Elring is OEM for m54 VCG). I also had a VR gasket fail on my S52, and replaced it with Elring, and it's good so far. As for doing 2-3 VCGs, I'd rather do 20 VCGs than 1 CCV. :-)

Ps. This is actually an X3. I've only done a CCV on a RWD e46 330i, and I am not looking forward to doing it on the AWD X3. Even replacing the X3 DISA was twice as hard than on my e46s. You X5 owners have all the room in the world.. :-)

An elegant solution would be to retrofit the sulev valve cover from the M56 engine. The valve cover is aluminum, has apparently a N62 CCV valve, but the cover has to be removed to access it. There is only one hose that goes out from the top of the valve cover and attaches to the intake manifold, meaning, you either take a sulev manifold (I wouldn't because the M56 is for a 325 car, so I think it's more restrictive) or one would just cap off the original intake manifold where the other original CCV hoses get attached to it. Also, I wouldn't bother with a new dipstick, just cap off the original CCV connection. Here is a detailed post on e46 fanatics. Be sure you read to the very end, where I posted a few tidbits.

Here is how that valve cover looks with the only 1 hose attached to the intake manifold. You can see where the CCV valve is lodged on the top - the black round plastic cap:

^^Clean work Dorin I agree this is the best solution - Pricey though especially with the "beauty covers" if you can find them -

I wouldn't care about the beauty covers, but from I read what people posted, the WHOLE thing incl intake manifold & beauty cover can be had from scrapyards for around 200 bucks. Not bad considering how much the OEM CCV kit incl. hoses cost.

200 for the cover, but watch out for having to convert to newer-style push-on coils vs older bolt-downs, which needs the newer ignition harness. So that can get pricey if you have an old E53, near as I can tell.

True, but AFAIK, my ex-e39 530 had push on coils and had the M54 engine. My son has the e46 325 and also push on coils....

That's true, I think E53 switched at some wacky time to push-ons. Probably just a generation 1 issue for early build-date E53s.

That's me. Now the Elring gasket is in and so far so good. The PCV & tubing was clear. The old VR valve cover gasket had completely failed and 5 of 6 spark plug wells were full of oil; I think a long left sweeper caused oil to dump onto the exhaust, causing the white smoke-out. I'm blaming the VR gasket for now, and will update if things change. Sorry for the alarm.

Another Update at 2,000 miles AFTER CCV Mod: Zero oil consumption.
See the detail of my setup in post #164.
