It is more likely that the oil passages are restricted. They are very small.
Or some other issue. Like the green O-ring seals failing (as mentioned in post #4 this thread).
If your Duratech has a live test feature you can trigger the solenoid.
Take the engine cover off and engine not running. Trigger the solenoid and listen for the solenoid to click. That would at least tell you if the solenoid is responding correctly.
You can also trigger the solenoid with a small battery like a nine volt.
Use the search function: There should be info on replacing the solenoid.

Yes, I definitely need to find a procedure to remove and test the solenoid.
