I screwed it in and started the engine. While the pressure reading at idle was better, it was still low enough that it worried me. It was dropping lower and lower as the engine oil temps rose. I shut it off. It still bothered me that it should got belly up after an oil change, so this morning I went out again. I decided to put more oil in it just on the off chance that it was too low. The stick is bright alum and it is difficult to read with clean oil. As I was taking the paper towels that I stuff in my funnel to keep the dirt out of it, a inch and 1/4 long Scorpion made his escape from it. I then took an air hose and blew out the overflow relief tube. The tube runs over my root tube and down through the bottom of the cage. I started the engine and the pressure readings were in the 19 lb range. I ran it at idle in the hanger for a while to see if they would begin dropping as they did before. They stayed around 19 to 13 lbs, and at 136 degrees oil temps. I decided to push it outside and see what it would do at operating speeds. All seemed to be working properly, so I took off and at cruise it was showing between 44 and 52 lbs of pressure. I flew for about 30 minutes or more and the pressure stayed where it should be. I went up high and cut it back to idle and the pressure was steady at about 19 lbs. I am not sure if my overflow was plugged (manual troubleshooter suggests it as a problem concerning low oil pressure) or if I just didn't give the new one a proper test. I have been called a pessimist occasionally.
