I have same problem. Water is coming trough hood hole and between hood and firewall and drains to the starter.
Winter hibernation in oil is my solution for bendix rust problems for now. Im also calling the better solution. I tried motor silicone for better water resistance but turned out that actually keeped the water inside better.
Actually dragster's PG adapter with Mopar starter have similar problem.
When it bolts upside down, draining hole is pointing to the sky.
