WK2 Snorkel

So based on this I should at least have another hole?

F1 cars use air ram but they need a huge plenum box to make it workable.
In fact almost every factory Mitsubishi, Toyota and aftermarket Airtech snorkel are facing forward as standard. Also check the ARB and TJM websites which show forward facing snorkels.

The reason for forward facing is to give a "Ram Air" effect at moderate to high speeds to compensate for the extra distance between the new snorkel's air intake point and the air box. It is usually a much longer distance.

The disadvantage of forward facing snorkels comes with torrential rain or very fast and steep entry to water crossings where you have to be watchful for waves over the bonnet as demonstrated in an earlier attached video.

You are right. I had in mind more the utilitarian vehicles like the Toyota Troopy and the Australian army G-wagon

Yes, many mining vehicles and military vehicles turn them around to minimize dust intake when in convoys. This is usually at lower to moderate speed. I have done this myself when acting as "Tail end Charlie" and found it effective. However this is not possible with some snorkels so "socks" are available as in-snorkel pre-filters. These are pretty effective provided you don't over oil them and change or clean them regularly. Another option is to change the head for a circular canister type but these are expensive to buy.

However none of these options are available with the Murchison snorkel, so I am carrying a spare main filter.

Re: WK2 Snorkel

Yes, the US military trucks I used to drive had circular snorkel heads on them covered by a dome, bell shaped protector so that heavy rains would not enter - if memory serves, as I retired 23 years ago. I never attended the official driver's school, my license was an additional responsibility, but I distinctly recall talking to Marines who did, and part of the training was fording deep water right up to their chin. The only way to drive any deeper is if the driver wore a snorkel or scuba tanks so he could breathe.

Unbound1 please keep us posted, I hope you get this straightened out. Also, am sending a PM to ask about your aux fuel tank, I'm interested and don't want to hijack the thread.

Whereas a bypass as I described placed low in the snorkel tube should clear all water entering it.



Furthermore the installation instructions, that had to be sent separately as they were not in the original snorkel package, did not mention any need to drill the 2 holes you ask about.

I have just completed 999ks today, I reckon 800 of them have been in the rain, I checked the air box on arrival I had a puddle of water the size of a 5 cent price in the bottom of the box and the filter was stone dry, in my opinion the two holes in the back actually work....I have driven in a lot of rain today and followed a lot trucks that were throwing up a heap of water.

Well Hutch, there must be something very different between your snorkel and mine because I just did a round trip Canberra-Melbourne-Canberra (1500km) in the rain and my Jeep air box had water over the bottom and a very wet air filter. BUT the Pajero accompanying me had a completely dry airbox and filter AND it doesn't have holes drilled in the head but a proper water escape below the tube. It's a Pajero branded Airtech snorkel.

In the attached photos you can clearly see the difference in the air boxes and the band of saturated air filter from the JGC. Photos taken the next morning about 11.00am as I got back well after dark.


I'd love to know the difference between your's and mine, if any, apart from me driving in heavy rain.

Yes mine is different as quoted previously mine has the two holes drilled in the back and they work....

Have u drilled holes in yours yet?

Yes the airtec snorkel has a different water dispersant system I had one on my Prado.

Yes, I drilled the 3 holes before going to Melbourne and still have the problem but to a slightly lesser extent. I also drilled them in the lower section of the extruded box as recommended by Stuart of Murchison.

DID NOT WORK as you can see by the photos.

As I am about to travel through the Australian interior I want this problem solved fast as I do not want a damaged engine.

Yes, the Airtech clearly has a much better dispersal system as I stated earlier.

I am really regretting spending the money on the Murchison snorkel. I bought it as a device to protect my Jeep BUT so far it has endangered my Jeep. NOT HAPPY.

If it is not fixed soon Consumer Affairs will be in as will my lawyers as so far the unit is NOT FIT FOR PURPOSE!!!!!!!!!!!!!!!!
