Camshaft deviation is 0.0 on one and -9.0, is it even connected...that is weird.

First of all, cam deviation values should only be check on a thoroughly warmed up engine, say after a 10-15 min. drive.  Second, if you get the same reading, you have a possible issue as the limits are +/- 6 degrees.

I just drove it for an hour in two directions and got the same reading....
I have been checking the oil and I see no debris on the last 3000 miles. I think I am just going to swap out the bearing it is going to have to be done anyway. I just don't get the 0.0 reading it is like nothing is being read. I don't think I am going to drive the car until I swap out the bearing. I thought ran great. 

What is your recommendation?

You haven't said what year the car is, so I don't know if it is a 3 or 5 chain engine; if it is the five chain, I would be looking at the wear pads on the short chain between the cams.  These are well known for wearing prematurely and causing out of spec deviation values.

I would start with the most simple 1st which would be timing. I think mine at some point was were yours is at after doing some work on it. I thought it ran great and thought for sure my timing was not the issue. Sure enough …..it turned out my timing in one of the banks slipped. V
