Intake manifold oil leak

Every Mopar wedge I've ever seen, from a 273 to a 360, and from a 361 to a 440, excepting of course the TRUE original "Max Wedge" heads, HAS that cutout and it is EXposed. I can assure you that it has nothing to do with your oil leak.

Could be a cracked manifold or valve cover, or gaskets. Improper crank case venting, IE positive pressure, increases oil leak problems. Could be an imperfection in the VC gasket surface of the heads which is NOT machined "as one might think."


Other advice given above, IE VC interference with the intake, and leaking bolt threads is also a possibility.
