Thumbs up - -CCV(Crankcase/Oil Seperator Fixed!!! w/Pics!!!- -

- -Well today I tackled the common CCV (Crankcase Vent/Oil separator) problem. My problem was a very loud intake leak sound and once I placed my finger over the side port on the CCV, the leak went away as best my finger could make it do. Also motor would shack back and forth, lighting in and outside the car would dance to the misfire that the CCV was causing among other things.
Here is the new unit: , , , .Here is a view from the front of the car of the old unit , .
Just before I started this I asked myself could the CCV be replaced without taking the intake manifold off. The answer is YES It can be replaced with out taking the intak manifolid off. Here are the intake manifold gaskets I bought a while back thinking that they were the problem .
On to surgery, first I started with removing the air box from the fender to the throttle body .
Once the tubing is removed you can see the 3 bolts that hold the CCV in place on the bracket .
As you can see
the three bolts are easy to get to. They are 10mm. After disconnecting a couple of pigtails and moving a few lines out of the way for clearance the CCV came out without much fuss , , . Once the old CCV was out, I took these picks to show them both , ,
the CCV on the left is the new one and the one on the right is the old one. After that itís just a matter of doing the reverse and making sure you reconnect any lines or pigtails that were disconnected. This is a go time to check all hoses and cables while most of the big boxy items are out of the way. Also check the hose coming from the bottom of the CCV to the oil dipstick to tube. After a while the rubber becomes spongy from the heat build up and if you look inside you can see that the inside of the hose is starting to deteriorate. So it would be best to change it at this time. Here she is all buttoned up back to normal . I was curious to see what the old looked like inside and out, so I took it apart and snapped some shots. I hope this helps anyone out there whom may have the problem I had with a bad CCV(Crankcase/Oil separator). I have more photos and info if anyone needs it. My car now runs and ideals MUCH, MUCH better. When I get to work tomorrow I will have the check engine light cleared and wait to see if it will come back on. I have yet to drive it since the work has been done. Going to fill her up before I go to bed just thought I would go ahead and right this up first. I still hear a very faint air sucking sound but it could just be me and my superman hearing when it comes to this car. Iíll get a second option from one of our techs tomorrow and see if Iím just hearing things. Just a side note, while the CCV was bad I did smell the fuems in the cabin from time to time and my OBC said my gas MPG were 20.9. I thought that was very strange, so Iím going to reset the MPG and the MPH gauges and see wha I get after a few tanks. Here are the pics of the old CCV in its nakedness enjoy. , , , , , , , , , , .
If I missed anything let me know. Here is the link to a thread that helped me out http://www.bimmerfest.com/forums/sho...d.php?t=214052. Thank you. Peace.

Were the vibration issues you mentioned occur when it was cold out in the morning only? did you have constant idle problems....even in warm temps?

- -The vibration was in cold weather and in the morning. I did how ever notice on warm days it was not as bad. I could be at a red light and with my foot on the brake it would shake pretty good. The idle was pretty consistant for the most part, say If was going from light to light about 3 blocks apart. Once I would get to the light, thr RPM hand would fall all the way down to zero and sit there. The motor would shake hard and the after a few seconds the hand would raise to about 300-500 RPM. There were times that the car would just die all together. One more thing, the leak at the CCV was so bad that after I found it and placed my finger over the vent port the motor ran fine then once I let go it died. All is will now though, the CEL light went off on its own after about 3-5 cycles of starting the motor. I hope this helps. Peace.- -

Good work.

Two questions.

First, did you replace the grommet that goes into the intake manifold and into which the CCV fits?

Second, you didn't mention the hose that goes from the bottom of the CCV to the dipstick housing. DId you just remove that tube or did you remove the dispstick assembly?

- -The only hose I wanted to replace was the hose coming from the bottom of the CCV to the dipstick tube. It is 10 years old and just didn't "feel" that great. Plus the end at the dipstick tube was hard to come off without a lot of work on my part and I didn't want to risk damage to anythng with it being Sunday. I will replace that hose once I go CAI. Other than that hose non needed replacing.- -

- -I didn't replace the grommet, it looked real good. No cracks and held the old CCV in place after I removed the 3 bolts very well. I would suggest that you inspect that hose and replace it if it is collasped or soft to the touch. You will have to take a pair of good pliers and work the hose off the end of the CCV first then off the dipstick tube. You do not have to remove the dipstick tube.- -

I replaced the CCV on my son's '98 323is a few weeks ago. It was the same part number as your CCV. Removal was similar. I managed to reach down to the dispstick assembly and pull the hose off the dipstick, then I just remove it with the CCV. I did replace the grommet, 13 41 1 733 217. It probably is not necessary, but I figure it's just a $2 part and I would want to do it over for that.

BTW, the 530 CCV is entirely different. And the 540i does have a CCV, but it, too, is different.

yes, it does. It looks slightly different though. Open your hood and look between the firewall and intake manifold. The CCV is on the back of the motor with the brake booster line and some vacuum lines coming out. It's an easy DIY.
