Racing Beat's Holley carbs have had a nipple for oil injection for decades. Works well enough. The oil doesn't seem to mess up anything.

I'd like to add a nipple to an Edelbrock so I don't have to premix. There is an undrilled vent casting for marine use that I'd like to drill and tap for a nipple. How would the introduction of oil affect the accel pump plunger and other carb seals? Any thoughts?
