I just pulled the C-clip and removed the spring and other stuff on my bypass valve as well. It was a lot easier than I expected. I just have to remove the driver's front wheel, one splash panel, the acc. belt tentioner and then put a 1-1/16" deepwell socket on it to get the valve out.
Immediately it idled about 2 ticks higher while cold. I let the car idle with the AC on until my data logger showed 195 F. I looked at my oil guage and it was one full tick above where it was idling previously. I took the car for a spin. Unfortunately, I could not tell a difference in the oil pressure while cruising. It appeared to be at the same position as previously. My idle oil pressure stayed 1 tick higher than previously even after I did a 1-2 gear pull and then let it idle.
Sorry for just using my stock guage. I don't have an oil pressure guage and I don't plan on buying one. I just wanted to post my results to let you know that it did work for me. I have already ordered a new valve that will be going into my car with a new oil pump and rod bearings next month.
