Quick update - just passed over 25k miles with this mod. At 214000 miles engine runs like new - no codes and no oil consumption! My setup in posts 36 and 41.

For how long you are using vr
I've used it and used China and oem all are same but you have to add rtv to avoid leak especially in oem from the agent otherwise it's the worst valve cover I've Seen and vr is the best

Hello, new member here. I've been lurking for a few weeks trying to get smart on a new to us 02/04 with 3.0. Thanks to you all I was able to determine that the CCV had failed as one might imagine would happen in AK in the winter. I was hopeful that I had nipped the issue in the bud with the PCV bypass but alas I also blew the VCG.

I used pretty much an identical set-up as the OP did after he modified it to attach to both sides of the air distribution box. I used a poly pex tee instead of brass which probably has a larger orifice, and I used 5/16" fuel hose from bulkhead CCV attachment to the tee fitting. This eliminated the need for taping or hose clamps. I used 5/8" heater hose for the front connection to the ADB.

I fully intended to follow the procedure to the letter, when I encountered some history of creative fixes: someone had used silicone sealant to fix a vacuum leak around the #6 prong of the ADB into the intake manifold. I found that I was able to do the bypass WITHOUT removing the ADB at all. I understand that it would've been better to clean all of the mustard out but I was afraid of what I would find under the silicone, and it wasn't leaking now. I also unfortunately was unable to separate the bulkhead side of the hose, but I got what I could out of the other. I've seen stories where these things endure worse and figured that it had been on a constant diet of the stuff anyway, and would be happier once it burned out all of that crap.

Wondering if the VCG blowouts are due to strain from increase in vacuum in an older gasket, or just means that I wasn't quick enough to catch the CCV... Any opinions? I am reasonably sure it has it's original VCG (110k) so it may have just been time.

In my case we purchased from a dealer, we may try to jump ship for a e70 35d, otherwise on the hook for plugs/coils/O2 sensors etc from exhaust oil contamination in addition to VCG repair. I'm now concerned enough about the obvious delayed maintenance that I would rather not keep this one if I can avoid it. The Carfax proved to be misleading at best. Anyway, the local dealer enjoys good rep and likes to try to keep it so we'll see how it goes, I don't think that they have that much into it. If I end up stuck with it I'll be here grinding away with the rest of you!

Thanks again to all, I would've hydro locked it without this forum. Cheers!

Sorry to hear about the issues you've discovered when doing the mod, I know how much it sucks to purchase a new vehicle only to discover how the previous owner glued and rigged everything. At your mileage those VCG tend to be very brittle from heat and age so doing the gasket is a great idea. The X5 that I did this mod on is still running strong on the original PCV valve and the engine has not showed any ill effects so I'm fairly confident in this bypass, considering the number of cars I have done this mod on I haven't had a single one report any issues.

The CCV failed, crankcase over pressurized and blew your VCG, oil around gasket and in the spark plug holes. Lucky it didn't hydro-lock or crack the VC

Follow-up 6 months and 3,000 miles later, zero oil consumption: not even a drop, dipstick remained at MAX.

- Remember to check your oil level on a perfectly flat driveway and engine off for about 4-5 minutes. Best is to check your oil level at the same spot in your driveway or your garage.

- Sometimes I checked my oil level at a gas station: even the slightest incline at the gas station can give inaccurate reading, i.e., can move the oil level to somewhere above MIN, but after I got home and parked the car in the same spot overnight, oil level is at MAX.

- Anyway, those interested in the mod can see my setup at post #164.

Ditto on the VCG - replaced with Victor Reinz did not seal well - replaced again with BMW no problems for >10K

Thanks for you work to put this together! My X5 with 167k has always used an excessive amount of oil therefore I plan to install your mod. What is the latest version that you would reccomend?

My 2004 325i with the m54 was ideling very rough. This ccv delete fixed it. I notice oil spots under the car now. Is that just what was in the ccv oil separator?

Ok, I've done this mod to 4, M54 engines now.
Latest one was my son's '03 325....he called me in a panic thinking he had blown a head gasket. Temps were around 14 degrees and all the mustard gunk in the original CCV system froze solid. Name:  DSC05368 (1400x1050).jpg
Views: 713
Size:  309.0 KBWe let it thaw out when the temps got up to the 40s and now he doesn't have to worry. The only issue I have is with my '01, 530...seems there's oil leaking out of the tube which did go to the dipstick. I think I may have a bad oil stand gasket and the oil is running down from that. Again, thanks for starting this thread....
