The rearward facing stainless snorkels came from the comp trucks, so when hitting water full sting it wouldn't enter intake, when in trees it wouldn't take the head off and if the car falls over they didn't break. Then it got transferred into the town cars

Hello, my name is Gareth, live in South Africa, grew up in the Eastern Cape and Transkie, was a teenager in the 70 ties!My uncle, who had a trading station in the Willowvale district, developed the "snorkel" as everyone has come to know it, because of endless vehicle trouble involving dust kicked up on gravel roads. He, uncle Ernie Smith, fitted these extensions on the vehicles! It was a winner, worked exceptionally well! A delegation from Toyota, Japan, made a trip to my uncles trading station! All the vehicles used, were Toyota! They were very impressed, promising follow a follow up, which NEVER happened! Never received a dime! All the best buddy 👍

Petrol and diesel are also incompressible, just like water. The air that occupies most of the cylinder volume, however, is compressible. Replace some of that air with water and you end up with a much higher cylinder pressure on the compression stroke, which bends rods like you said. The fuel doesn't compress, its atomised into droplets and just doesn't take up much space to begin with. It's also a controlled amount, unlike water entering the intake

Heres the rub, last two decades up until 2021 I have utilised a Safari snorkel, in the last couple of years with the purchase of a now well modified Hilux I have elected to not use a Snorkel. The snorkel equipped vehicles have ALWAYS dirtied up the Unifilters much much more than the non snorkel vehicle. I must admit I drive most of the outback roads and tracks of Australia and am so happy now I have not spent $ on a snorkel. I simply do not drive in the dust of other vehicles or thru water more than 700-800mm deep and guess what it is cool to go around or camp up and wait until water levels drop by 24 hours. OH and by the way those snorkels are noisy bastards.

Yep, I had a SWB Prado, dust got past the filter and made its way to the crank shaft bearing, plus every where else. Catastrophic failure, the whole engine was kaput. That was one very expensive lesson, especially in the middle of the Kalahari desert.

a couple of points from over here in blighty, a rear facing snorkel top is a good idea if travelling through our greenlanes as I have lost two snorkel heads over the years after they got caught on tree branches. I do leave it facing backwards as our lanes are short with lots of road trips between them. If not laning for a while it goes back to facing forwards. After breaking into the air system, I always check the air tightness of the pipework and snorkel by using a haynes manual to seal off the top of the snorkel pipe ( after removing the top ) if the engine stalls then I feel happy it should do its job.

I had an AEV snorkel for dust on my 2013 Jeep JKU. I loved it. With the pre filter cap on it I could go more than twice as long without changing my air box filter. It was a great mod

Thanks Ronny! I have been looking for few day for a complete 4wd snorkel tutorial on YouTube. Today, I found your new posted video, perfect timing) Greetings from Canada!

On my 70 series I swapped the standard Toyota raised air intake (with all its leaks) for a relatively cheap TJM snorkel which is fully sealed and does not require any cutting of the bodywork. Rather than use the TJM supplied ram air intake (which I guess does not really have much of a ram effect) I stayed with the original Toyota cyclonic head. It was a bit fiddly to fit because of the slight mismatch in pipe diam but a piece of 100mm pvc pipe cut lengthwise serves as a filler. End result works like original equipment without the leaks.

Great advice indeed, I recently watched a different 4wd show where one driver went fast in a water crossing sucking water down the snorkle and drowning the engine. So drive smartly when going through water :)

I put one on my 1985 4 runner with a vortex top. Keep most dust out. Going deeper than headlights..engine fan issues. Great video, thanks.

My Ram 2500 has an AEV snorkel. There are 2 connection points that are held together with hose clamps. One is under the fender and the other in the engine compartment near the airbox. It's probably pretty water tight that way. However, i decided to have insurance by installing 4" diameter rubber plumbing couplings over the joints. As for the airbox, all drain holes have been sealed. I learned early on when i blew up a perfectly good 4.0L engine on a '97 TJ. I also have had 2 friends blow their enginess on a water crossing I had no problem traversing. If you are expecting water, a snorkel is cheap insurance.

great video! Imho you are explaining things best in the offroad community.
Without exaggerations and drama 👍🏼

You can always use a Donaldson type head on the Safari type snorkel instead of the sock in dusty conditions .Easy to clean.Just empty it each day and you can see the build up on dust in the bowel.I find this more effective, Cheers.

[janfourie]

The duckbill valve is also to release water that came past the snorkel head. The ram-type was tested and are very in-effective to remove rain from the snorkel, but the valve still clears.

Thank you Ronni great subject to talk about there is one thing you have for gotten to bring up on this subjected recovery on a tint tray to cover your in take up as the turbo spins up on the back with no lube when the engine is not running

I’m only new to 4wding (6 years) but this is honestly the best advice given to new people entering the 4WD playground.
It’s not all about show or water crossing!
I did my research before getting my snorkel and only put it on as an insurance policy nothing more.
So big thanks Ronny for putting this out there and helping the new 4WD people in making the right decision.🥃

This is THE best raised air intake video on the internet! Well done, Ronny! 🥇

[ADayInTheLifeOfJames]

Legend Ronny; loving how far your channels come buddy! You should be proud of yourself coz we all are. 👍

I had a tjm and a genuine Nissan one on a couple of cars ranger bt50 f250 always got full of dirt and bugs and crap in the filter front facing nilly drowned a patrol in the rain with a front facing Nissan snorkel.
Then went to a stainless 4” rear facing. No bugs hardly any dust better for filter service intervals.
Thanks for the video.
Also the plastic in the heat with a sock pre filter over the ram head doesn’t like a lot more boost they suck the plastics in especially if a bit of dust / mud clogging the pre filter.
