Well after a long time and a lot of head scratching I got this one figured out. It got worse and they finally decided they wanted it looked into more. I used signal generator on ids to watch actual icp and pcm interpretation. pulled rh valve cover. New check valve is broken. Not so new anymore I think it's been 2 years since I had put in.

I think the pin lock is mechanical. Pin is locked by spring pressure and the pcm commands oil pressure to unlock pin then adjust timing as needed. I also think that if oil pressure gets low it cant get them neutral

Got this truck fixed after replacing the lift pump, fuel heater, fuel return lines and seals on metal lines. I let this sit 2 days without being touched. She runs great when started and driven after sitting now. Thanks for the help. Tony
