Totally agree. However, while motor oil may kill the cats, the only way to know will be to run them and cook the oil out with exhaust heat. I don't know the condition of the exhaust manifold to head bolts, but at this point I wouldn't risk breaking a few just to see if there is oil in there when we all know the answer to that one (see post 38). If the cats fail deal with it then. They may be fine. Lots of failed AOS that oil soaked cats came back from.
