Go back to the diagram. Item a is the thermostat and the item listed as a star valve is a is the oil filter housing pressure relief valve (supposed to allow oil flow by bypassing the oil filter if the oil filter got plugged). I am not sure if one of those could block off the oil flow.

Also, there is supposed to be an oil pressure relief valve in the oil pump.

Some filters have been known to come with a thin O-ring compared to others.

I did write this one.
