Snorkel and air box drain (1 Viewer)

[kcjaz]

I recently installed a Fabulous Fabrication snorkel on my 200 and drove it around in the rain today. I had installed a check valve in the air box to deal with rain getting in the snorkel. I’ve read some threads with some people saying to plug the existing drain hole. You do not want to do that. A temp plug for when u r actually attempting a water crossing would be ok (probably good idea) but you don’t want the drain hole permanently plugged. Here’s why:

Heck valve worked:

In the air box. You can see some water has been getting in:

Airbox inlet at elbow:

This isn’t enough water to hurt anything but you need to have a drain. My check valve works but I will need to keep at eye on it to make sure it doesn’t get plugged.

What direction is the check valve instead? Is it water tight?

How does a check value that allows inlet airflow to the engine block water??

Check valve allows water to drain (out of air box) but not air or water in through the drain hole. It’s a tiny little valve inserted in a small hole in the corner. I have some more details in the Fabulous Fabrications group buy thread.

Any concern that it can get clogged by dirt or the other junk that ends up in an air box?

Lots of heavy equipment uses a “duckbill” valve to let any potential water and even some of the dirt in the air box out, while maintaining resistance to air flow back in. Key advantage is there not being any mechanism to clog.

Potentially. A duckbill would probably be better but there isn’t any room on the low point. I’ll just keep an eye on it and if it clogs, I’ll just go back to the drain hole and plug it when I go into submarine mode.
