I was recently putting new gaskets and o-rings on my oil pump and didn't find the little spring when I took the oil pump off. Should I be concerned?! And will it work without it?

bump

anyone?????

It's there for a reason. It likely serves a pressure relief purpose of some sort. Without it I would expect either the engine to starve for oil, or the oil to bypass the filter. I haven't looked closely enough to see what it does but I would never attempt to use a pump without the spring.

You may want to start over with another oil pump. I have one in my pile of subie parts if you need one.
