I'm not sure man, my tuner is working it out. They've been really good talking to all the right people to find the problem, no hint of trying to mask it by just locking the timing.
Phasers are being replaced. Oiling is stock, and the right weight oil is being used for the clearances.
Apparently the intake cam is all over the place on idle when it's hot, and it's noisy on idle. Oil galleries should be ok, its had the run in oil changed out already. They've done a very controlled and deliberate run in process, which is good to see.
