leak no more!
Well, luckily it wasn't even the oil guage line. The valve cover gasket gave out. And I think I know why. 2 weeks ago after I changed the oil, I was checking for any loose bolts and tightend down the valve covers.. the bolts were easy to turn. Anyhows I guess after squeezing the old gasket and then taking it for a drive from Long Island into New York City, the gasket had just about enough from highway driving and then stop and go.
Thanks again for you everyones concern and help.
