    Snorkel & Rain

    Driving home at 100 km/h into very heavy rain tonight; had me wondering if any one has ever sucked in too much rain and caused trouble with their Snorkel. I have a D2 TD5 with a Safari and I seem to remember reading somewhere that you have to slow down in heavy rain. Something that I have never done so curious if anyone has ever had trouble. Tell us your story if you have one.

    I have never had any dramas and wouldn't worry about it but if you are turn the head around so it is facing the back of the vehicle

    i doubt you'd actually manage to get enough water in there to do anything more than make the filter a lil damp.....

    Sounds like myth is busted. From my experience and your posts sounds like someone should tell Safari not to include "slow down in heavy rain" in the instructions.

    think of the velocity of the air going through the snorkle, the size of the water drops getting sucked in, the number of times the air changes direction before it even gets to the filter, everything except water vapour (even then not ALL of the vapour) is going to either fall out of suspension in the snorkle, or its simply going to hit an internal surface and slowly trickle down to the airbox.... where it *should* drain out of the ducks bum vent on the bottom of your airbox.....

    *if* you've literally sealed everything so the entire system is watertight right through to the intake manifold, you'll need a fair bit of water to get into the system before it does more than make your air filter soggy

    This warning is simply to save their rear ends from any one complaing from something like this happening

    I have definitely found rain wets the air cleaner element in heavy rain in my RRC with LRA snorkel with ARB type scoop. When I changed my element, it was stretched and misshapen from being wet then drying out, but there were no holes

    I now turn mine around while at home on the coast.

    If you look, none of the UK snorkels like Mantec have forward facing scoops,and neither do the Toyota factory snorkels.

    safari

    i think you will find the safari brand snorkels have a system where the raindrops hit the back of the air ram and then the water feeds down to the outside. check the below link

    Took a D2 on a trip as well as others. He his a creek crossing very fast and apart from popping out the headlights, enough water went into the snorkle to stop the car. When we opened the air cleaner box the air cleaner was saturated.

    His greatest concern was the sensors under the passenger seat as he sat in the creek awaiting recovery.

    I'm guessing that the Donaldson/MF pre-cleaner snorkel-top may be better in heavy rain, but it'd only really necessary if you're driving in torrential rain on a regular basis. Otherwise, I wouldn't worry too much - I'm sure they've tested the system under those conditions.

    Here's another thought, though. If the rain was heavy enough to cause concern about water ingress, you'd want to drive slower anyway.
