Small oil leak
Mine was leaking from most of the area's at the back of the intake. At first I thought it was the distributor gasket or oil sender leaking, as I was sure I had sealed the intake well. I honestly think my issue was just using the blue sealer I bought from jegs. It did great at the front, but not on the back. It will be difficult to get the intake sealed once it starts leaking without removing it. The "Right Stuff" sealer would be the way to go if you do take it off to re-seal.
