While doing an oil change I removed the hex head plug on the bottom (FE570) of the motor to drain a little better, however a little spring went sploing, and a ball bearing went plop into the old oil. What is the purpose for this ball and spring? I just placed the ball back on the spring and pushed it back up and in, in retrospect I wish I had investigated what it looked like up inside. Could that ball have slipped off the spring when pushed back up inside, or is it a tight hole?

That is the oil pressure regulator valve. The spring length is supposed to be .925".
It appears that you re installed it correctly with the ball on top of the spring. Tightening torque on the nut is supposed to be 14.8ftlb.

According to the shop manual, that doesn't appear to be a worry. This device is for when your oil pressure gets too high going through the filter and allows the oil by pass the filter and go straight to the motor.
As long as you put the ball on top of the spring when you re assembled I wouldn't worry about it.

Thanks Dale, I should have simply taken the time to shine a light up the hole to determine if there was a void at the bottom of the plug hole, or simply a bore hole all the way up. It was only at the end of the day (laying in bed) that I considered that the ball could have slipped off the spring (if there was a void at the bottom) while I pushed it up in.
