That test port plug is impossible to get out. I've been trying to an hour and a half and the 5mm allen socket wont go into the plug all but maybe .5mm. Its not enough to put any torque on it with out stripping it.

I'm trying to hook up an oil pressure gauge to check pressure. Is there any other way to hook the gauge up?

The pressure switch looks just as much of a bitch to remove as well. The coolant lines from the oil cooler keep you from getting a 24mm wrench in there.

Any other tips?
