1998 Sonata 2.0 - Doing head job found mystery steel tube under car

hi, I'm doing a head job on a 1998 Sonata 2.0 and I found a steel tube laying under car on shop floor, about 3 inches long and 1/4 inch thick with a pinhole orifice on one side and open on other side. Looks almost
like it's for a vacuum line. concerned it might be for oil flow because head is back on engine but I still have to hook every thing up. Any ideas out there.... tomorrow I will try to get a good pic of it and attach it to this thread unless someone knows for sure what it is thanks guys joey m...............
