Looks like I have a bigger problem. The problem is that I don't know where the oil is coming from. I removed the exhaust manifold and took out the center stud. When I removed the stud, the threads were dry. No oil. Everything is a mess so I can't tell where the oil is coming from. The only thing above the exhaust Manifold is the cam cover but that does not appear to be leaking. I cleaned things up a little and I'm going to have to reinstall the manifold and see if there is still a leak. If it still leaks, I have to remove the manifold again and look for fresh oil.
