2001 XC70 644A:camshaft reset valve faulty position. 13 deg

[HollowTank]

Short story:

I had my belt and cam + crank gastkets replaced after oil leak. I then replaced the PCV system myself. I now have a check engine light for high camshaft adaptation values. Is the belt on wrong or could I have messed up some wiring?

long story:

I have a Volvo 2001 XC and moved from the northeast to the gulf coast within the past year.

I was working on a construction site that required some slight off roading to get to the parking area. I left the site, drove home, and a few hours later when I moved my car, noticed a huge puddle of oil.
My local indie said I blew my cam and crank shaft seal. They replaced the seals and timing belt, and told me the likely culprit was the PCV system. I decided I would tackle that job on my own.

I borrowed a car for a week and replaced the entire pcv system using the IPD kit (I plan to add some comments to the current threads, but it was def overkill). I probably only drove about 25 miles on the new seals before I garaged it and installed the kit.

everything seemed fine, then about 100 miles after the belt was replaced, a check engine light came on for cam shaft reset valve - faulty position. I checked the shift degrees using my chinese VIDA, and all four flanks were around 13degree shifted. The values were varying slightly, so they appeared to be current.

I took it back to the Indy to have the belt checked, and they told me the belt is on correctly according the marks they made when they put it on before, and that they think I messed something up when I put in the pcv system. I suppose it is possible that I screwed up some wiring under the hood when I installed the PCV system, but this is the only error I’m getting.

They cleared the code and about 100 miles later it's back. The adaptation values read 13 degrees even without the engine light on, so i'm not sure why the light takes so long to come one

Do you think the belt is incorrectly installed? Is it possible for a bad install to require a 13deg shift?

Could screwed up wiring be causing this? Did I leave something unplugged, damage a wire, or mess something else up?

Any ideas would be greatly appreciated.

Thank you
