    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 :neutral:

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