I take it that the bug has carbs or just one carb, the problem could be the fuel pump leaking into the crankcase or the carbs themselves leaking fuel down into the manifolds and it finally finds it's way into the crankcase. All this happens after the engine is shut off and sets in what they call a hot soak condition. Hope this helps.

thanks Mark---was wondering if it was the fuel pump or the carb or maybe the piston rings---

If the fuel mixture is rich, gas could get past the piston rings into the engine oil while running. A rich condition can be confirmed by the color of the spark plugs and the smell of the exhaust.
