After hunting around the web for a few, it sounds like the spring is from the timing chain tensioner. It looks like there is a button on the end of the cylinder, that end goes in first, then the spring. See if the spring is the same on both ends, the picture looks like it's smaller at one end and that end goes into the tensioner, not the bolt. I'll include a screen shot of the picture.
Good luck!
