engine noise when idling 850 1997

I recently purchased my '97 850 turbo wagon with 107,000 miles. I have noticed that when my engine has idled for a few minutes when I'm in traffic I start to hear a somewhat loud ticking - a lot like the usual valve noise when starting cold, but constant until I pick up speed. After I've driven at higher speed, the noise goes away and the engine idles quietly.
Could this be a worn oil pump? other oil circulation problem? a bad lifter? Anyone have other ideas? I would appreciate any input.
