- -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 it’s 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. I’ll get a second option from one of our techs tomorrow and see if I’m 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 I’m 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/showthread.php?t=214052. Thank you. Peace.

Wonder if my 99 can be accessed the same way? I would love to manage this without pulling the intake manifold.
Yesterday Check engine came on again with P1189. Idle was bad and low.
Today I checked for leaks and I found out that CCV have a bad gasket.
Tomorrow I will put a new one so...

How in the world did you get the CCV valve out??? i tryed today for 2 hours and still couldnt get it out, so i just unplugged the bottom tube and flushed the CCV with carb cleaner... well the car started to work better... but back to my question how did you get it out??

hi,
can anyone tell me where it's located in a 540i6?
thx!
Hmmm My OBC says 20.9 all the time too... never changes. Is that indicative of anything? ('97 528i)
so does that big piece of shit do the same thing for the most part as a $2 pcv valve in other cars?
p.s. little tip when taking close up pics, hit the botton with a little flower on it then it wont be blurry and worthless
Yes. Back in the day, before we drove E39's, we tuned up our cars with distributor caps, rotor, wires, plugs, fuel filters, air filters...and a new PCV (positive crankcase vent/valve). Most cars had them sitting right there, on top of the valve cover, the E39 hides it down near the throttle body.
I changed mine and wrote about it 4-6 months ago:

My deaership said I have an oil leak at this location(oil seperator) they want $540 to fix it. Where would th oil be leaking from? The actual unit ofr where a hose goes into it, or where it goes into the intake manny?
01 530i "to borrow from 1 is plagiarism, to borrow from many is research"
please note: in production dates 9/98- the CCV is located UNDER the intake manifold.
getting this fixed on Tuesday at an indy shop $798 + tax. Half the price of stealer. what else should i get done at same time?
