Purge control valve vac hose help!

Hi all thanks for all you do and all the info on this site. I'm in the process of restoring my 2003 e39 530i. I bought it in 2006 with 33k and now it has 225K. A new house and a layoff has forced me to put maitnence on the back burner for a while. Little by little i'm working on getting her back to tip top shape.

So i just did ccv from bav auto and new valve cover gasket and coils, icv clean etc. I'm getting the po444 so i got the PCV and thats where the problem lies.

While wrestling out the older valve the vac tube that goes to the intake maniford or throttle body came out. I can't for the life of me find where it goes. I've searched the board and I even called bav auto and they got me the picture; it the same pic that I found on realoem.com. Still no luck!

Any help is appreicated; trying to get her back together; so its the end that allows the vapor to be burned by the engine when the valve opens up. I appreciate any help.

Chad

EVAP system in all cars is very similar.
Hose #3 simply connects to the intake, either upstream or downstream of the throttle plate.
Use a mirror to look for the nipple in the intake throttle housing.
Or run engine and listen for hissing (sucking) noise, you will be able to locate the nipple.

Cutting out at full throttle: the car tells you to slow down otherwise you get a ticket.
J/k....

OK, replace the fuel filter if you have not done so. Info in forum.

lol....i did i was hoping that was the case. I'm thinking crank position sensor. It was right around 4 k....<3k if power is lacking i understand its the vanos seals. It would die and I'd get a misfire cylinder one.

We traced out all the vacuum hoses in the M54 engine.

Typing /vacuum hose F3 in the best links nets these, for example:

Did you get that purge valve hose back on the intake manifold? It's hard to reach with the manifold in place.

bluebee thanks a million...steve not yet. I was preparing for some meetings i have today; i took a minute to go out and feel around but sure enough I couldn't put my hand on it. I'm thinking I need to undo the CCV/oil seperator again. I plan on making it happen tonight! Is it possible to reattach with the manifold in place? or am i better off removing it?

Thanks a million guys! As i'm still gaining some bmw knowledge if anyone has 1978-85 240d/300d mercedes diesel questions/dodge cummins questions/ questions on making biodiesel please hit me up! I know this is a BMW forum but thats what I can bring to the table. As we all know the bmw straight six is one of the best motors built along with that the cummins straight six and the mercedes straight 5 3.0.

I'll keep ya'll posted on my progress!

Any chance this PCV going bad could cause a vapor lock with my fuel tank/prohibiting max fuel flow at high rpms?

That hose is the only one I have never changed on my car--it's hooke to the intake in a place that I can't get my hands on--and there is a clamp that would need to be dislodged before you could remove it--are you sure that the hose that your wanting to remove is leaking air--you could remove the purge valve and then plug that hose on that end and crank the car and then go under the hood and check and see if it's leaking by removing the plug and then reinserting it--you would hear the difference in the sound--the charcol cannister is in the back driverside under the wheel well--there might be an air leak back there causing your problem

I helped a person replace the CCV and some vacuum hoses on his 330i with a M54 engine. When he removed the purge valve from the bracket, the hose was dislodged from the back of the intake manifold. It did not have a clamp, but that may just be the case with his car.

I did manage to get the hose back on the vacuum port on the backside of the manifold. It was not easy, but it is possible. IIRC, I positioned the hose as best I could and just managed to get two fingers on it to slip it on the port by reaching under the manifold.

The CCV was in place. The intake boot was out, and I think the wiring box was still unmounted.

Note I changed my other post. It was the purge valve, not the ICV.
