Great idea! I think the duck bill is also meant to release the grit that the hyclone thing spins out of the incoming air. I also suspect that the safari snorkel at least also works like a sump that collects a certain amount of water.

Dang, I was hoping to convert my TD5 into a amphibious vehicle! ;-)

i just serviced my safari snorkle, it turns out that even after being installed by a reputabull 4wd company, it was not 100% tight, the conection from the wheel well to the box was not cyliconed all the way around. so water would have come up from inside the 1/4 panal into the box, also the flex part of the air box has parreshed and was rotten, i had not seen any online so i repaired it my self, after pressurewashing it enoughf to get the dirt out i baked it in the oven at 110C to dry it, then covered it inside and out with rtv cylicone and cyliconed the elbo entering the box and i chose to fill the small hole at the bottom and the duck bill seal, if i feel i may have water in there ill just pull the rubber plug off and let her drop out. to tell the truth, i was crusing around with a snorkel i new was not 100% but after pulling it apart, it was anything but tight.

dose any one know of a test to do to check for 100% seal

Man that was hard to read!

In reference to your final question:

Disconnect the intake pipe closest to the intake manifold and seal it up.
Pour water down the top of the snorkel (use a hose) until it is full to the brim.
Look for spot where the water leaks out.
Drain water and allow it all to dry.
Seal leaky spots.
Refit intake hose to manifold.

Note: Remove air filter element while doing this test.

Simple, fit a thick rubber glove /cover over the intake, if your snorkel / airbox is sealed the engine should stall
