What do you guys recommend?
For those of you who have done it yourself, how hard was it? Any DIY on the internet?

DIY, while you are doing it replace all the gaskets concerning the intake manifold. its about time for them to be replaced anyway.

The job is a bit tedious, but I wouldn't say it is terribly difficult. Before starting have the CCV and all three hoses that connect to it on hand. And it is a good idea to have a few feet of 1/4" vacuum hose handy. I didn't find it necessary to replace the intake manifold gaskets on my 01 525i, but it can't hurt to have them when you replace the CCV.

Note that while it is barely possible to replace the CCV without removing the manifold, not doing so increases the difficultly markedly. Any by not removing the maifold you don't get a chance to clean the oil out of the intake nor can you properly inspect the other small hoses that connect to the intake.

Words of truth to be sure. If you don't change all of them now, you're just prolonging the inevitable and making more work for yourself in the future. The CCV itself is about $75 from the dealer, tack on another $225 and you'll have every O-ring and gasket you'll need to put every intake leak worry to bed for a long time to come.

I think it is harder to do the CCV on the Inline 6 rather then the V8's right? Cause of where it is located (underneath the intake gasket)

Well, it's part# 2 in this diagram. Trouble is there are 7 Torx head bolts that are on tight as F***. There are several that can attest to having to break out the vice grip plyers to twist out the bolts after the torx stripped. There is only a few inches of space between the rear of the intake cover (CCV IS the cover) and the firewall. It's possible, to do I suppose if you don't mind breaking your back trying to reach 7 blind bolts that were tightend by the hand of god himself, then be my guest.

If you do decide to attempt changing the CCV with the manifold still in the car, Be sure to post how it went :eatpop:

Bump... What does everyone think?

I just had my CCV replaced by the Dealer.... i got it done for FREE. Just had to pay a $120 diagnostic fee. Don't ask how... as I almost punched the service advisor in the face, but he eventually gave in to my arguments.

This is the thing... i looked back there and found that it would be a lot easier to take the manifold off, as you would not have any room to really work. You will need the gasket cover (which is basically the CCV - they're connected) all the required tubing, clamps, o rings. Theres a cable that runs under the manifold that you will have to make sure is secured... otherwise it will have leakage and will be a pain in the *** to get back to. Other than that.. the job is doable. Get a Bentley manual and give yourself at least 8 hours. It takes a technician around 4 hours total. Good luck!

if you have the knowledge, time and resources to do it yourself, you'll save a huge chuck of change for your next mod :).

but if you are not sure of your abilities, this is not the job for you....had mine done + gaskets and valley pan by an indy shop...

How much did it cost you total?

1000 beans...

How difficult is it to change the CCV (PCV) without removing the Intake???

isn't it under the manifold on the six...?

yes... but a mechanic told me they can work around it...

Just got mine changed. If you got about $300-350 a good indy shop can do it. I wouldnt pay much more than that. Good luck!

1000 beans...

i woulda came out and did it for that price :shifty

I replaced the CCV and all hoses on our 01 525i without removing the manifold. Took all kinds of twisting (I had to break the old CCV to get it out). Stupid me used non factory hoses and the top 90* hose now has a hole in it 3 months later. Just ordered new hoses but I am not sure how I am going to do this a second time. Note to anyone that reads this on the I6.. REPLACE ALL THE HOSES WITH OE ONES! BMW makes great cars, but terrible cup holders and now I really hate the CCV, it is way to overly complicated.

"it is way too overly complicated" hahahahahaha
:lol

I think that goes for all BMW's!

What part is the CCV called in the Bentley Manual? I looked under crankcase and found zip. Also, could anyone post a link to the part in realoem for a USA config, 4/1999 build date, 528iT manaul? Thanks!

They call it a cover. They don't call it the ccv. Look at the above diagram. It is the cover on the back of the intake manifold in the diagrams. It will cost about $75 to buy.

I just ordered everything to do the job from oembimmerparts. They have good prices. Ask for max. Be sure to have the last 7 of you vin.

Only $45.00 for the CCV.

Thank you. Actually, the I6 is rather different than the picture of the V8 above. Nonetheless, your suggestion did point me to the correct picture on realoem.

As far as symptoms, I have read about doing the vacuum test. Just for sh*ts and giggles, I removed the oil filler cap while the engine was running and the sucking noise I heard sounded like a sick moose. Is it normal to have that with a functioning CCV? Did not have time to get a section of garden hose to trace, but the noise was coming from the general area of the intake manifold/throttle body.

Most of the conversation regarding the CCV has been from 540i owners. Since you have a 528i, I will be interested in knowing how hard the install of the CCV ends up being. Assuming that you removed the intake manifold, did you use the existing gasket or new? Any type of gasket sealant when replaced? Did you need to pull the valve cover?

If it turns out that I need to replace my CCV, I promise here on bimmerforums to take pictures and post a DIY for fellow 528i owners!
