Are you sure that the fuel pump, if you have a mechanical one, isn't ruptured. This will pump fuel into the oil.

Also, a carb. with high float level [flooding] will flood gas into the oil.

I've never seen an intake leak cause the gas in the oil. If the gasket isn't sealing at the cylinder heads. Well you'll have a vacuum leak and it will run terrible and won't want to idle.

I'd check the pump and carb first. Just my $.02.
