Is this possible, Oil leaking externally from head gaskets? I replaced the upper and lower intake manifold gaskets successfully last winter and havnt had any leaks internally or externally on the intake gaskets. These leaks have been happening for some time, I have oil that runs down the back end of the heads along the gasket, down the block and coating the oil pan and transmission pan. Both heads are leaking in the same spot (back ends along gasket) and running down to the oil pan. The valve cover gaskets look dry all around the edges. I just find it hard to believe both head gaskets would be leaking in the same spot externally with only 125k miles. my oil is staying nice and clean, as well as the coolant. They are not mixing. Has anyone had problems with the heads leaking oil externally on these? I don't really want to pull the heads for oil leaking out of them, but its annoying having an engine and bottom of car coated with oil.
