I did a smoke test and the only leak I have is coming from around the alternator.

I believe there is a crankcase breather hose that runs under the intake manifold. Can you upload images of the location the best you can? This is what it looks like. Check out the images (below). Please upload pictures or videos in your response of any problems so we can see what to help you with.
