One could consider coming off the timing case cover. The accessories and their drives plus the water pump would provide visual concealment. The forward bulkhead would provide the much needed separation between the vent and the crankcase helping keep oil out of the vent. Boring holes in the timing case cover has less expensive impacts to the engine than having something go wrong with a hole you just put in a major casting like the block.
