Welcome back.
It's really easy to do, but it does require a mechanical oil pressure gauge. Most parts stores will lend one to you. Basically, all you need to do is remove the electric oil pressure sensor on the engine and screw in the mechanical gauge. When the engine starts, the mechanical gauge will indicate what pressure is being produced.
Here are the directions for checking VVT oil pressure. The attached pics correlate with the directions. If you get a gauge at the parts store, tell them you need a 1/8th x 28 pitch BPT adapter for your vehicle. Don't use the incorrect thread type or we will end up with a new problem, oil leaks or worse.

CHECKING VVT OIL PRESSURE
This test can be used to help diagnose VVT faults.

Disconnect and remove oil pressure sensor (1).

CAUTION:
Threads in block are 1/8”-28 British Standard Pipe (BSP). Do not install a National Pipe Thread (NPT) threaded adapter, this could crack the cylinder block.
Install an 1/8-28 BSP male to 1/8-27 female threaded adapter (2).
Install oil pressure gauge (1).
Start engine and record oil pressure.
CAUTION:
If oil pressure is 0 at idle, do not perform the 3000 RPM test
If oil pressure is 0 at idle, shut off engine. Check for pressure relief valve stuck open or a clogged oil pick-up screen.
Remove oil pan and inspect for debris (Refer to 09 - Engine/Lubrication/PAN, Oil - Removal).
Remove oil pressure relief valve (Refer to 09 - Engine/Lubrication/VALVE, Oil Pressure Relief - Removal) and inspect, if damaged replace pressure relief valve.
If pressure relief valve is ok, replace balance shaft module assembly (Refer to 09 - Engine/Lubrication/Pump, Engine Oil - Removal).

After test is complete, remove test gauge (1) and fitting (2).

Install oil pressure sensor and electrical connector.
