RE: Oil pump
Some PB Blaster will help that stuck plug.
Why do you want to increase the oil pressure? Spec is something like 3-50PSI. If you want more than you have now, run thicker oil. Too much oil pressure robs HP and doesn't provide less wear.

RE: Oil pump
DON'T DO IT!
All these "adjustable" pressure gadgets and heavier springs actually do is cause the oil flow to the crankcase to be starved at low RPM.
Oil goes to the valve train first, and when it gets enough pressure, THEN it starts going to the bottom end. Long as the lifters are rasttling, again, don't do it!

RE: Oil pump
I run 30w winter, 50w summer. I've had a "performance" spring in mine since I bought it, 80,000 miles ago until I switched to 20-50 one time. I had basically NO oil pressure. Went the the dealer and bought a stock spring and it came UP 7 pounds (same oil)
So again, replace the spring it you want, but use a stock one... Just my opinion based on my experience.
