FAO Carlo and any BMW tech's. HELP!
My X5 had a missfire recently. It's the 3 l petrol engine. It was eventually traced back to a burst inlet manifold. A garage removed the manifold but we had to take the car away to get the lpg fitter to do some work on the system. Then my mate offered to refit the new manifold as a casher.
Anyways he's fucked if he knows where the below pipes go. Pics arent great but surely someone can help. The hose leads back to the rear of the engine bay at drivers side and iirc he said they go to the servo. They are some sort of vacuum hoses. When blocked up the car drives just fine but need to get them back where they should be
oh and i think the AFM has to be disconnected also and then car idles nicely. Weird.
I need this sorted so we can get it back on gas.
The 1st pic is just beside inlet manifold towards back of engine bay.
2nd pic shows main hose to relocate and also the bit i'm pointing at.
3rd one might be a clue if part number is there?
Cheers

One of the boys thinks it may be the wrong manifold mate have you made sure its identical to the old one as there was a change in the way the pipes went.
Pipe 3 should run up from cyclone vale to above the manifold between cylinders 5 & 6 pipe 7 runs along top of manifold to front at cylinders 1 to 2

thats showing the 2 pipes. 666 and 603.
my mate who did the car is about to come here for a look. we were pretty sure the manifolds were correct. they looked the fucking same

Carlo i'll call home and get the chassis number to PM you.
I've just discussed it on phone with mate mattie who fitted it up. He's looking at the thread and will post up his thoughts. Seems that everything in your pic is in place!!
He can describe what is what.
It's driving him/us insane!

hello folks, Im the man who put the new manifold on.
Both manifolds were identical there were no additional hoses or anything.
on the old manifold both hoses to the cyclone valve were cracked and broken so i used the new ones that came with the manifold. all the hoses breather related ie to rocker cover etc are all in place.
The issue that im having is that the hose that steve has posted pictures of has no home. I traced the hose back to the master cylinder/servo. The hose comes from there round the back of the engine to where we see it in the picture.
NOW the confusing part, just in front of the adjuster unit or the flapper valve i belive it is called (black box bolted to manifold) i have a hose coming from under the manifold with a plastic valve (sucking jet pump as called on Real oem) as do i also have one fitted to the hose that we have no home for. There is no where that this hose can connect to under the manifold.
As a temp fix i have plugged the hose with no home into the top of the sucking jet pump that is sitting infront of the flapper valve and the engine is idling fine and running perfect all be it with the airflow meter disconnected.
scratching my head

bollocks lol had one in this morning for same valve swap
From under manifold hose with 2 90o bends one vertical and one horiztonal plane to sucking pump jet then 90o elbow then another hose with 45 angle to underside of large inlet boot rubber from airbox to manifold.
The long hose with 1x 90bend goes from rocker cover to cyclone lower horizontal hole
The U bend shaped hose with a smaller take off goes from under manifold to top of cyclone
The other long hose with 2 90 bends goes from cyclone bottom hole to oil drain on dip stick
Then smallest bore hose middle of cyclone goes back under the manifold to the adjuster unit
The only other one is from brake servo with right angle check valve goes under into manifold
You sure not got 2 pipes mixed up somewhere underneath the manifold its easily done!
