intake manifold gasket and installation

well i put it on last night and thought all was well because my vaccum leak was gone, but i drove it to work this morning and smelled oil real bad, so i popped the hood and i have oil leaking out the front and back of the manifold!! so aparently i didnt use enough rtv... I didnt use a whole lot because i didnt want it to get into my oil valley... So tonight i have to pull the intake manifold back off, and scrape the rtv i did have on the front and back off and apply a bigger amount.
