Is this normal VCT behavior?

one thing I did notice though is my engine oil pressure seems like it's all over the place. it's not low or high necessarily, just sporadic. This might be normal, I don't know, but I can't really find any examples out there that really confirm what I should even be seeing.

This is what it looks like at idle. it can swing 20 PSI in a split second.

If it's a high accuracy transducer (sensor) it's possible to read like that. If you ever watched mechanical oil pressure gauge for hydraulic system, that's why they are typically oil filled.

You're probably right, but it would be comforting to see other logs out there showing something similar, or someone familiar with these to confirm it, but I can't really find any. Any examples I've seen were from gen 3 motors, and they don't seem to have this behavior.

Nobody? I was watching it today and noticed that it seems like the angles separate slowly as the truck warms up. The duty cycle slowly increases on both as well. One thing I also noticed is that VCT_INT_DIF doesn't seem to show that it's happening. They still hover around 0.

The first thing I thought of was oil viscosity. Or more accurately, as the oil heats up, the viscosity drops and camshaft control is less precise. Remember, it takes pressure to move the phasers.
