i have the same problem. I have a Kargomaster Congo Rack and run a snorkel would require some presidential modifications.I to, would like a snorkel. But I also want to retain the stock airbox and filter. I always regretted the day that I stepped from stock to a snorkel on my TJ. I went with Volant because they included an enclosed airbox of their own, I just was never satisfied with the cone filter. I also hated how the darn thing always seemed to be in the way. If I wanted a light bar or a rack, forget it, wouldn't fit anymore. I am trying to come up with my own solution to this problem, but it's tough.
Without knowing what damage was found, this is hard to say. It only takes a small amount of water to cause a rod, valve, or other internal part to bend. It doesn't need to break to cause the death of an engine. A little water can cause the piston to get ****eyed in the cylinder, causing a scar in the wall. Once this happens, the death of the engine is just a matter of time. Of course, the OP would be happy if his engine isn't damaged.....ok, I watched the video a couple of times. It looks like the first puddle was the culprit (IMO). It looks like you hit it way too fast. So have you or the dealership had a chance to look into it? I would be really surprised if you actually did a large amount of internal damage. Like others mentioned, if it truly was "hydroLOCKED", you wouldn't even be able to try to crank it over. It is possible that you have a wet air filter that is choking out the air flow or that you got some sort of electrical component wet that shorted out. Possibly in or around your coil pack.
So have you heard anything from the dealership? Did you open up your air box to take a look inside?
So in your opinion, does its placement make getting water inside the airbox easier, harder, or about the same as a TJ? Is it possible that water is hitting fan, fan is tossing water onto bottomside of hood then running in the airbox, or do you feel problems are generally caused by other factors?pretty much right under the passenger hood latch. the stock opening is shaped to match the contour of the hood in that area.
