It's been a while. I finally tried cranking over the engine to get oil pressure built up. I have a tee on the oil pressure sensor for a turbo feed and oil pressure gauge. Neither had oil pumping through them. I slowly undid the oil filter and it is still filled half way with oil. As that is how I installed it. I am unsure of what is going on. The oil filter housing is twisted about 90° that is what TCD told me to do so the wastegate would fit. Need help!

You could try spinning up the oil pump with a drill to see if the oil pump is working - oil should start squirting onto the drill bit once you spin it up if the pump is working.
To do that, there's a cover right over the oil pump, you have to remove the airbox to see it, it's a single 13 mm bolt I'm pretty sure. Then you pull the circular thing out from under it with the BMW logo on an indent in the middle. You may need to do a little bit of prying with a screwdriver to get it moving. That should expose the gear that translates the motion from the intermediate sprocket to the oil pump drive shaft. You take the gear out, which leaves the oil pump drive shaft there, and you just put a 6 mm or something like that on it and spin it up with a cordless drill. I did this to prime my oil pump after I had removed it doing the oil pan gasket and it worked great. Once you're spinning it up there's a stream of oil directed at the drill bit cuz that's usually where the gear sits. -
You used a drill bit? Wouldn't that scratch the metal and get flakes everywhereComment

No oil pressure

Fyi I was swapping an LS motor with a friend. Brand new out of the box. It took about 2-3 minutes of cranking to get oil pressure at the gauge.
Some pumps perform very poorly at low rpm. Since your car doesn't have assembly grease on all the wear points I would try priming the pump.

Thank you guys. Finally got oil coming out of the pressure sensor hole. Had to take out the plugs so I could spin the engine much quicker. And took a little bit of time. Appreciate it. Good to knowComment
