Explain that one.

IMHO. it`s just ANOTHER "Diabolical Device" (added to a long list of other DDs) that is destined for early failure on these cars....
There are MANY first-time BMW buyers (mostly non-DIYers) who get into their ownership before doing the necessary research, and quickly become disillusioned when the repair bills start mounting up (they thought "German engineering" would save the day....)
Most of these people will NEVER buy another BMW....

Does anyone know where this hose that's right in the middle of the screen connects to? I connected the Cvv lit up and even put back the throttle body and forgot about this piece and have no idea where it goes. It has one of those squish tabs on the top left of the screen and its slipped to the car itself near the bottom right. This is all I need to finish this project up. Lmao. Thanks!
are you referring to the hose with the F connector? that goes on the inake hose

That looks like where the dip stick goes.

One of my favorite discoveries of a failed CCV, just listen to this suction. So much pressure it cracked the valve cover (very common for hairline cracks on these M54's):

Along the lines of what happens with a failed CCV on an M54 engine, is this thread, with lots of pictures and three videos with a distinctive loud chinking sound clearly audible that was caused by a plastic CCV having been accidentally sheared in half.[*] Have you ever heard THIS SOUND inside your M54 engine?

There is a ton of research in that thread, showing how to determine that it's not the DISA and that it's not a manifold backfire (valve leak testing) but that it's the CCV.

There's also good information about a CCV delete with a PCV that can pass emission visual testing.

I suddenly have hope for the future of my 2000 323i manual transmission...I did not realize the longevity of these cars... 400k that is quite a few miles. I have had my BMW almost a year now and it has been a love HATE relationship. I love the car...Hate the way it was previously treated. I have replaced countless parts, sensors, relays, pumps, hoses, you name it. I failed smog 4 times before FINALLY passing...I am still rolling the snowball...I have always worked on my own vehicles with much success and read countless forums all different makes and models. This is the first I have ever signed up for. This car has serious HEART.

Why does the M54B30 engine have LTOCRs? Fuel economy is the accepted reason. The problem is that LTOCRs require a constant and consistent crankcase vacuum. The CCV is supposed to provide that vacuum. While the CCV is apparently ok for the other engines, it's inadequate for the M54B30 engine. Hence, these engines burn oil.

I believe this CCV design is common to the M52 and M54 engines only. However, the only M54B30 engine has the LTOCRs. That's why the CCV needs to be replaced with an oil catch can. It works, relatively inexpensive and easily installed system.
Old thread, I know.

If the low tension oil control rings require a consistent level of vacuum, (actually absolute pressure,) how is using a simple "catch can" supposed to generate the required vacuum and regulate the crankcase pressure correctly?

Despite popular opinion, BMW did not design the CCV to be complex for that reason. The OEM CCV must perform the necessary crankcase ventilation function and provide for a sightly negative crankcase pressure ( ~ -3 to -6 inH2O water column,) for all operating speeds and loads, while minimizing lube oil loss from oily aerosols induction.

Who made a rule stating older threads should not be revisited? Why do you believe this?

If something new can add to an existing topic thread, why not add it?

When the original question/problem is something that needs immediate attention, posting a response a year or two later serves little purpose. THAT`S why....

I agree, provides info that may be useful when someone is searching old threads for a solution to their current problem... years later.
I was taught in other forums, proper etiquette is to look for answers to my problem in previous posts, rather than automatically starting a new thread.

Catch can questions

I am at the stage where I am going take on the catch can. So far this is what I have done up to this point. I have not put anything back yet b/c it seems to me the catch can is the last item in the list of things to do.

- Took off the expansion tank
- Took off the DISA and rebuilt it
- Took off the fan (will replace it with an electrical one)
- Took off the belts and replaced all the pulleys and tensioners.
- Took off the valve cover and VANOS. VANOS disassembled. I have the new rings but waiting for the anti-rattle retainers. I don't think my VANOS rattles but might as well do it since it is out of the car. It does wiggle a smidgen. Hate to go back in again to replace those some K miles later.
- Took out the alternator in preparation for the OFHG replacement. Oh btw, i lost a bolt down the crevices of the engine when I took off the power steering reservoir. I hope I can find it and not have it fall into the internal of the engine when I take the oil filter housing off.

So now I'm looking at the CCV thing and researching on its replacement with a CC. I bought a CC without a return port so I guess I will be capping off the return line into the crankcase. I have 2 questions to ask of you.

1. I have been watching 50skid videos on YouTube and his videos are extremely helpful. His videos recommend not doing an oil return line to the crankcase for cold weather. Does this mean I will have to empty the can periodically vs. if I do the return line, I don't ever have to? Should I do the return line? I've bought a CC that does not have a return port, just IN and OUT ports.
2. When I install my CC, what hoses go into the IN port and the OUT port? I am guessing it's the hose from the valve cover that goes into the IN and the intake manifold hose goes to the OUT. Is this right?

Before this project, I was pretty apprehensive about the whole thing. Once underway and taking my time, it was not so bad. The most difficult one so far was the expansion tank. It was hard to get out. I think I broke it but I have a replacement. The one surprise was the fan clutch nut. I thought I really had to work hard on that nut b/c of rust but once I had the leverage, that nut went out easily. Too easily.

Thanks

Aha! The good luck of the forum shines on me! After posting, I went back outside looking for that bolt and found it!!! Potential disaster avoided.

I guess you didn`t notice, but we have a Sticky Thread devoted to this very subject....it might be a good idea to add any future postings to that existing thread

Thanks FastBob. I've read that thread and the other linked threads in it. I have googled othr sites and read and read. I was just overwhelmed. If someone knows the answers right off the bat and let me know, I would appreciate it.

Now I broke the hose that runs atop the intake manifold along the fuel rail (?). I don't know what the part # is. Does someone know?

Oh and I got mayonaise in my hose lines and CCV.

Got my CC in 400 miles ago. Opened it up last night and saw some Starbuck cappuccino. Looked tasty. I put in a stainless steel wool pad because someone said it would help catch more. I will put a CC in my wife's brand new 2018 CRV after seeing how good this is.

Since you completed the install, have you checked the amount of vacuum at the oil filler hole ?

I did not, FastBob. What do you look for? Unfortunately my VCG didn't sit right and is leaking a little bit of oil. I need to redo that.
