Major OIL leak in intake manifold/head gasket on 2005 5.3 Z71
Oil is spraying under the intake manifold on the valley plate between the heads
I posted a few times here, but nothing like this. My engine has been leaking oil for a while. Now I opened up the hood to see oil all over the top of engine. Could this be a cracked head? What are the symptoms?
Oil in the valley leading to the intake manifold, which is also covered with oil.
I would appreciate any replies or suggestions. Thank you.

Start your truck and watch under the hood to see where its coming from...could be something minor or something big...just an idea

Oil runs down and back. It is leaking from the highest area that is wet. Clean and validate.
