It's been a tough week for my two XC70s. My 04 is currently down as I believe the collar sleeve is stripped. And now my other XC is turning a one day's work job into a nightmare.
I bought an 05 XC with 150k and leaky cam seals. I replaced the cam seals and followed the instructions of this write up to a T which I believe to be the correct way to do it.

At the same time I cleaned the PCV system and put it all back together. Now the car runs as shown in the video. Codes on vida are ECM-670C and ECM-671C, both indicating the angle of the exhaust camshaft is too high. These codes only get triggered sometimes when I start the car. I am leaning towards the exhaust cam being a tooth off even though I'm absolutely certain I put the CVVT back on correctly. I know for a fact there was noticable in and out slop in the CVVT, would this be causing my problems even though it was fine before? Thanks to the ViDA I was able to see live data with the car running. Somewhere I read that if camshaft adaptation was more than +/- 8 degrees from 0, the exhaust cam is a tooth off- my value appears to be 30.6degrees when running and about 26-28 when the car is first started and idling.
Parts replaced so far: maf, exhaust cam sensor near hub.
This is the data I'm gathering from the 05 and a video at idle:
This is data from my dads 07 XC which luckily hasn't broken, (finger's crossed.) I see a noticeable difference in the ECM-Exhaust camshaft adaptation reading.
I am really stumped, I am 99.99% sure the timing is "right" considering I first lined up the marks on the crank, the cam to timing cover, and the rear of the cam when the sensors are removed. I used a cam locking tool on the cams when doing the work. Then I spun the motor two full rotations and checked it all again. Any help or input would be greatly appreciated.
