Well gentlemen I think I have found the problem... first no slapping! Thanks to your help and a little of my own blood (stupid hood) I may have found and corrected most of the problem so far for under $10. But I still need one more part. So I finally got time to take apart and inspect. I was taking the intake out to check lower intake boot and disa valve. When I touched a vacuum line and watched it disintegrate before my eyes. Seriously it made me laugh to watch that. I found 2 small cracks in the intake boot and temporarily patched them with electric tape and duct tape (already taken off) I then began replacing vacuum lines. I get a great deal on stuff like that.
First start after still made a little noise but stopped in a few seconds. let it run about a minute.
second start. no noise idled a little lower. let it run about 2 minutes.
third start. no noise let it hit operating temp then a little revving... 1.5k slow rev(no noise) 2k slow rev(no noise) 3k slow rev (no noise) just about to do a slow 4k rev when my neighbor yells down. " So you finally figured out your vacuum leak!" I've said probably 10 words to this guy since he moved in. I shout back up "yeah I think I did". He then says "I was wondering when you were going to figure that out!" come to find out he has a mini and a 330 both not stock. I thanked him for not letting me know the problem sooner. He said he knew I would figure it out sooner or later.

I then decided to take it for a test drive. about 50 miles into the test drive. I get my first kill story!!!!! I catch up to a little green honda civic with BMW badges riced out! after laughing out loud with my widow down he heard me. We make eye contact he shouts out "BMW bitch wanna race!" NOTE I can see the "H" on his steering wheel. I really don't think he saw the grill or logos or for that matter even really knew what a BMW x5 looks like (but he does now) He revved that big ol fart can exhaust the light turned green I took off I hear the bumble bee getting quieter with a couple times it sounded like he was going to catch up (vtech kicked in) then he'd shift and I pulled away my X was in rare form. and now because of that little bit of fun.....I WANT AN X5M!!!! or any turbo model. yes it's on my Christmas list...and Birthday list as well as any list I get something free.

Thanks again guys
