1998 Saturn SC2 • 4 cylinder FWD Automatic • 120,000 miles

Describe your problem. 1998 saturn SC2. The serpentine belt tensioner was loose from the mounting. When I removed the tensioner, I noticed a hole on the bottom right of the tensioner mounting (engine block), with oil in it. This hole corresponds to the location of the timing chain tensioner.I was concerned about whether the hole is supposed to be there, or whether my loose serpentine belt tensioner may have made this hole.
