Swap or Rebuild!!!

Hey Guys,

Although I had been a member on here for a decent amount of time & must admit I'm a silent browser hence not many or any contributions will be seen as in my 4 years and 100K miles of owning a 4.4l M62 upgraded to look like a 4.6ls, I never had any issues with the car that any of us had never had... and solved.. Infact, someone had done a thread recently about the E53s most common problems & crankcase ventilation was the only thing I never had issues with. I stil have my X5 even though almost everyone wonders why I put up with it. I'm sure I dont need to explain that here. So sadly enough, its sitting outsde my apt in Grand Prairie, TX looking all nice outside but almost dead inside. Following is my story. Suggestions on what to do, how to get past this one & where to seek help in or around my area would be highly appreciated as getting rid of it is NOT an option.

I have a 2002 BMW X5 4.4l with almost 200K on the odo which was running fine til it came out of the shop after a valve cover gasket n vanos seals replaced. One day after pushing the car past 120mph (frequented on my car), very prominent tapping noise was heard n calmly driven home. Oil sludge showed all around the motor under engine bay. Oil level dangerously low. Refilling it muffled the noise but didnt erase it. Next time I drove was on my way to the shop who changed the gaskets but STOP ENGINE OIL PRESSURE warning came up in the middle of the highway. Stopped, let it cool & then started. Light was gone, tried driving back home. Noticed the light on again w warning when lost power on a climb abt a mile b4 reached home. The last mile was tortorous & almost n0t making it. The car seemed to run better once its on a higher gear. The shifting was extremely rough. I finally glided to a stop as hydraulic brakes seemed inactive. I dont know what to do or where to take it or what to replace. Rebuilt kit seems the way as my car had never had any engine issues & wud alwax drive like a much newer engine than it had on ita odo, no significant leaks, no tapping, no excessive oil consumption before this. Plz advise in the right direction as I'm absolutely clueless & I know there r more ppl trying to con in the name of help than who actually help & I truly dont have a loaded pocket.
