Ok, you have to give more information. Where do you see the oil? I would take a paper towel around the head gaskey you installed and check to see if there is oil coming from the gasket. I replaced my gasket and it was still leaking, I had to replace the gasket cover itself because it was old and warped. There are a lot of people that can help you in this forum, but you have to give them specifics to what you are experiencing for them to help you out.
