I:iagree: with you because as I look further today, 1bolt is missing on each side but it doesnt appear to be any gasket there at all. I was kinda wondering why they do not listed it under the exhaust diagram, and I cannot find them on any website, they only have the ones for the (X5 3.i) but not mine which is a X5 4.4i

Wait, so you do have a 4.4i? Then who's blue 3.0i is that in the pic a few posts up?

Exhaust manifold gasket needs replacement!
 

Thanks alot (weasel) for keeping-up with me, now you make me believe there's no such gaskets like that existed on my exhaust pipe because my blue X is a 4.4i with M62 engine. So now I just have to look for 4 new bolts and nuts because the only two that left there are welded with dust and would not come out easily.

This is just for reference photo only but my(01 X5 4.4) is 100% the same as described and exactly same color in/out. Except this one is a 3.0i. Otherwise if you see this one, you would not want to see mine because my X5 is shiny the same way even more...

Thans alot bro..

But I'm still confused... the blue X in the pic there looks like it says 3.0i on the fender....... The easiest way to end my confusion would be a pic under-hood I guess. :dunno:

Here's one of the major job I've just completed on my (BMW X5 4.4i)
I've been searching the entire web for pictures about how to perform this heavies jobs on my: (2001 BMW X5 4.4i M62) but unfortunately no body seems taking their chance to do this type jobs. Amazingly! I came across of: E38 BMW 740i/iL M62 Intake Manifold Removal

which is a link showing you how to do the same job, but on a different BMW models. However I have to say thanx to the guy who has posted these pictures on the web because by following them I was able to succeed and also saving me:$ 3,265 dollars jobs in labor. Please don't get me wrong! the entire job cost me:$405 dollars, only because my car was due for tune-up service and this is a perfect time for me to do everything at once. But some parts are not pictured.
Because the procedure of the intake manifold removal, replacing all the gaskets: rear, front, under the intake took me about: 8hrs job.

See pictures below for details....

Pull out all eight of ignition coil connections. You will need to pull the metal clip upward and as you pull it upward, take out the connector from
the ignition coil. It is tricky, but not too bad. We need to unclip all the connectors so we can move these electronic boxes out of the way. There is
a box on each side of the engine. Pull out (most of the plug sensors) and the knock sensor(3) connector. Loosen (4) 10mm nuts and you got yourself a loose box! Be
careful pulling them out yet. You will need to take out the connectors that hook to the injectors. Take a look at the bottom of the box, you will see
4 injectors hooked up on each side. Uncliping is a pain in the (S) specially the two last injectors by the firewall inside, but with a little plier, you can open the thin metal clips and once you unclip the metal, injectors may pull out free easily from the electronic box wires. However in my case, I removed all of them completely and do not use them anymore, because I found it more easy for future removal. And once you screw the two electronic box on top, they holds tightly connected on top of the injectors, so there's no need to have an extra ignoring clamps there to keep injectors in place.

I was by myself guys! and this was inside the parking lot of autozone 3 miles from my house. imagine trying to finish on time so, my car won't stay there overnight and taking pictures at the same time.

In order to remove the intake manifold, we will need to remove the plastic engine/cylinder cover, (unhook the injector's clips are the most part on this job, otherwise remove the throttle body and the top fuel rail together with the injectors are easy. You may used 2 markers with different colors just to identify certain plugs. Certain BMW's model are much different than other because I found the job more easy on my car than E38 model explained.

(REMEMBER THIS WAS ON A: 2001 BMW X5 4.4i M62)

I hope this helps for some of you... Because The $tealers will charge you $$$Thousandsss of dollars to get to this point, now you can do it for free. At this point, you can clean out the intake manifold, the fuel injectors, replace the back plate of intake manifold easily just like I did! Good luck! And for those who need to replace the valley pan gasket, you will need to remove the water pump and take out the center "cap and seal" part... However I do not mess with it and mine looks ok, once I do not have any leaking antifreeze under the vehicle.

Be careful on the gas pedal when testing the car later, because as the engine notice there is no more vacuum leak, the compression now build-up inside the entire intake system pushing his way back normally through the muffler now, which resulting the car to take-off like a jumbo airplane.

Nice job with pics, but you should have made a new thread for that. Now the intake manifold DIY pics are hidden in a transfer case thread...

I'm still trying to figure out how to make a simple link with those pictures, but I also posted and shared this heavy job with many other BMW's forum in the related task. Meaning if you search for: vacuum leak, intake manifold gasket removal, or search for code P0171/P0174/P1158/P1160 the tread will likely take you to my job and pictures above.
