I had the same idea with the EGR gasket, should be off a ford I believe. I changed my mind tho, seemed to hard of a seal, no flex. Your best best is to get the right one or buy a gasket roll, about 3 bucks. Simple razor/scissors, pen, outline or general Idea of what you need, you can whip up a gasket for anything.
post some pictures on your setup and some of the oil spills. If it was clocked with the center(CHRA) having drain pipe angle wrong, it could be the cause of the oil.
A little RTV like suggest above is best also with most gaskets.
