everyone is missing the main point here that the snorkel is DESIGNED TO SHED what tiny amount of rain would actually make it into the vertical opening of the snorkel head...

Lived in Seattle and the outskirts most of my entire life.
Yes, it does rain here a lot.
We had wind and a nice rain storm yesternight.
Do I flip the head around on my snorkel?
No I do not.
Have had the snorkel on for a year come next month.
Most snorkels such as the Safari ones have a water separator system built in:
I have checked my air filter many a time after a nice rain storm to find it perfectly dry.
I have never rotated it backwards either like some do.

All Safari Charge Air Rams feature a highly effective water separator system built right into the air ram in order to remove rain water from the incoming air stream - thus ensuring safe engine operation through even the most torrential tropical storms

I have the Safari Snorkel like Corey has. I've driven through two tropical storms this summer with 60mph winds and torrential down pour....didn't turn the snorkel head around.......and had absolutely no problems. I was also driving at highway speed. The only modification I've made is I took a piece of home window screen and cut it to fit behind the intake grill, then glued it in place. I was getting alot of big bugs stuck in there and some made it down to my airbox.

Hey now, it's MY job to break out the numbers lol. You stole my thunder. But yeah, here's another way of looking at it.
Seeing as how our yoters are 2.4L 4-cylinder four-stroke engines, the displacement per cylinder is 0.6L. Lets assume that all it takes to hydrolock an engine is for a single cylinder to have half of it's volume filled with a non-compressible fluid (we'll say water for this example. though it's not really since a hydrostatic pressure of 6.89kPa reduces volume by ~3.4e-6 of the original volume). So theoretically 0.3L of water entering the engine on the intake stroke could hydrolock the motor due to the "non-compressibility" of water during the compression stroke. That would be roughly 1.2 cups of water at any one time to fubar the motor. You'd have to be in one HELL of a storm to get 1.2cups of water into any of the cylinders during the intake stroke with a motor turning at 1500-3000rpm. You'd literally have to force 1.2cups of water down in 1/6,000th-1/12,000th of a second to get it all into one cylinder depending on your engine speed.

Different calculation, same result. You cannot hydrolock a motor in rain (unless you hit a puddle with your cold air intake, but not your snorkle).

i couldnt find a picture of one but there are water wicks made for street/rally cars that go on your intake that allows water to be spewed out and the air to go where it needs to go. my friend has one on his car. it works good, ill get a picture.

Better luck next time you try parking in a lake. Honestly, what is clean rain water going to do in small volumes? Its going to go down the intake, into the cylinder's turn to steam and exit out. NO sensitive electronics, nothing to worry about. You might worry about cold shocking the metal, but I've never heard of rain causing any engine to crack.

^Yup, been around forever. Mostly used for keeping EGTs down so you can bomb more fuel boost. I use water injection on my Cummins. Though it's a water/methanol solution. Good stuff.

I have never rotated it backwards either like some do.
im going with this considering he has thought about it,done it,and then checked it thoroughly..i really cant see any RAIN situation on earth that would disrupt things considering the snorkels design and all the other info..i guess the only real worry for water would be total submersion or maybe goin under a waterfall or somethin...i feel pretty good bout it now and i think the o.p should now too.
stay dry!

If you are that worried about it, get a moisture eliminator like they have for the engine rooms on yachts. You can aim a firehose at those things and water doesn't make it through.
