I don't think it is 4 in the diagram. I just replaced mine. The oem version has rubber to the plastic midsection, back to rubber on the air valve bolted to the head. The joints between the rubber and plastic are small diameter and very, very snug, and the plastic midsection is about a foot long.

Well I just tried checking the wifes and it doesn't look anything like the other one.

Her's is a 2005 and the other one is a 2001. Both 3.0's but they did the plumbing different I guess. There isn't much of anything behind her x5's intake.

I guess the main thing tomorrow is to find out if the side I didn't check has vacuum on it or not. If it does I need to cap it for now and get the check valve ordered.

This is for the M5 but I'm sure it would crossover.

I think you had it as of post #8. Here is a pic from my 2001 3.0i when I had it apart last summer.

Thanks for the pic. I should be able to know for sure using that tomorrow.

If the other hose is connected besides those two capped out spots I will know for sure that's it and it should have vacuum on it.

That would definitely be a noticeable vacuum leak engine running wise :)

One has to wonder if the SA was giving problems and removed. Back when I had the SEL pop up about 9 years ago I did a lot of reading on the subject and remember that the pump seems to fail if the system is left unused and open to the air. Again, going back in the not so reliable "Wayback" machine, youtube had a video of someone opening and reconditioning one of the pumps to save the cost of replacing. (I just checked and the price has dropped to around $100.)
Be careful you are not opening Pandora's Box.

Well if nothing else I have to stop the vacuum leak via plugging the hose. Smoke came out from there when I did the smoke test.

Well I haven't got it plugged yet but I was able to find out that it is for sure the hoses in question and all that is missing is the plastic check valve.

For right now Im going to plug the hose that has vacuum on it.
