Helo: Cam and Eccentric shaft sensor issues
 

I have a 08 BMW 4.8 (E70 with a N62.) The timing chain guide on the passenger side, in the middle of the intake and exausht cam, broke and I replaced it. While I had the valve covers off I replaced the valve stems, did new seals, spark plugs, and coil packs. Because the work was done with the motor in the car the eccentric shaft, and camshaft sensors took a beating. When I fired the car up after the repairs I got 8 codes: P1040 ( Virable Vale timing), 3 missfire codes 4, 6, 8 cylinders, and both cam shaft sensors B on both banks reading high. There is also metallic tick on both sides now as well. Even though I used an AGA knock off tool, I still pulled the cams ( it was a lot easier to complete the job.) I torqued the eccentric shaft and intake shaft to 20 nm on all of the bolts. I used the timing tool to check the timing on both timing chains 3 times, sping the motor 2 rotations each time. I still need to change the oil but was waiting to be done with all the work first.
With all that said I still cannot find a good source on the resistance on the mentioned above sensors to make sure they are working properly.
I feel that the eccentric shaft sensor is broke and is engaging the selenoid causing the issues.
The car almost idles normally when cold, but when warm, almost "lops" like a taller cam is in it like older V8 with a bigger cam.
Does anyone know of a good source to the resistance of the sensors, so I can test them with an Ohm meter or have any suggestions? Thanks in advance.

Fixed. The eccentric shaft sensor was broken when put back in. The metal sound was the lack of fluid in the lifter.
