    I started to have oil leak from manifold exhaust gaskets. I replaced the gasket and the oil is still leaking from the new gasket. I uploaded an image where the oil is leaking. Its leaking from the squared ports in the cylinder where the manifold connects.

    It looks a little on the picture that it was leaking from above the gasket? Maybe it’s coming from the valve cover gasket? Cleaning the area first would be best and then driving for a while to better see where it’s coming from!

    The oil is coming from the manifold exhaust gasket. I’ve checked the valve cover gasket and its good.

    Looking at the picture I notice the burnt  oil on the exhaust manifold itself.  You say it is coming from the  square ports.  To me it looks like it is coming from above the exhaust manifold and leaking back to the spot above the quare port are and dripping down. It is possible that it is dripping down from the intake manifold.   Check around the front of the intake manifold for any oil residue.
