In theory, those metal impregnated epoxies like JB Weld will work, but whatever you select, be sure it says it can be in constant contact with oil and can withstand 300 deg F or more. I would apply the epoxy on both sides of the hole. If it is large, I would add a piece of sheet metal inside to sandwich the epoxy on the inside and provide reinforcement, while still applying an exterior layer. One thing I don't like about the two part epoxies that come in two tubes like JB Weld or in a double syringe arrangement, the stuff is real runny. So you will have to be real patient and do the gluing in stages, like the inside first, or buy the metal epoxy stick, where you break off what you can use in a few minutes and kneed it together. It has the consistency of putty, so it lends itself better in your instance. I need to take my own advice on that as I have struggled and become very frustrated with the two part stuff running and sagging too much. And when it finally does reach the thicker consistency I want, in 30 seconds, you can't do anything with it anymore. There are also supposedly some adhesives and gasket making products that may be more suited for that repair. Without reading one of them, I can't remember exactly, but I'm pretty sure the copper, high temp, silicone gasket maker is oil resistant, but you'd have to check that. If I had a choice, I'd go for that first before the epoxy if it is rated for oil contact all the time.
