Hi Guys

I have a Camel Trophy steel snorkel with the falt ait intake....When driving in rain the snorkel is sucking water into the air filter box. When I disconnected the hose water was not longer coming in....

I am thinking to make new air intake with a more inclined top so that it will not suck water as much....Any ideas?
Has it happened to anyone before ?

Thanks

Safari/Donaldson and other ram heads are designed so that rain will impact the back wall and drain out of the snorkel head before they reach the tube. Maybe you dould do something similar. I have a donaldson ram on my snorkel, and have never had any rain/water reach the filter. The air filter should stop any water reaching your engine, but it is not a good idea for the filter to get wet.

Mine was doing this in heavy rain, so I turned the scoop around. Although the scoops are designed to throw the water to the back and drain out the slots, some still seems to get down the tube and on to the filter, as mine was all sort of sagged when I looked at it. However I think I lost a lot of the ram effect which many will say doesn't exist, so I turned it back yesterday.
Water will not harm paper filters. In Seth Efrika they wash paper filters in the mining industry..
Just turn it around when it rains.

My old man went through a car wash in brizzie with his 200tdi offender and bent 3 conrods because of his safari. He was coming back from fraser is. and saw a sign saying 4wd carwash 'wash off all the saltwater'. water squirted directly down the snorkel and the car did a hydraulic. Moral - dont go through a carwash with a snorkel. He got lucky and it only cost about 800 to fix (inc labour).

I guess I will need to source out or make my own snorkel head as mine is the Camel Trophy style all steel....it is bad design in my opinion the roof racks kept the water away as I took off my roof rack

Jay,

My snorkel, as you are aware, is for sale - free shipping and as always, free consulting

I am suprised that the carwash didn't damage the safari head with the big rollers

it was a high preassure water car wash.

By the way, my scoop is a Donaldson type although no name appears to be the exact shape . Still lets some water in, but that was in VERY heavy rain. Why not buy one of these. I think they are available in UK.
I also have a Donaldson "Top-Spin" which I plan to use in bulldust. I believe these would totally exclude water. But it is a bit too high for my garage so I do not use it all the time and do not have any experience with rain.

Water or oil in an air filter increases the pressure drop across the filter, as well as weakening the cellulose fibres. If the binder in the filter isn't good enough it will mean your filter can fail. This could be in the form of rips or tears, or even small "pinholes" which are difficult to see.

So the bottom line is - if you wash your air filter, it may look OK, but it may not work anymore. I suspect the filters used in the mining industry are more likely to be made of cotton or glass fibres, which are much more washable.

Most diesel filter housings have integral cyclonic pre-cleaners which should remove any water droplets getting past the snorkel, before they get to the filter.

By "Top Spin" do you mean with cuts so dust can escape?
Or the classic prefilter with "dust bowl"?

As I have this,and it lets water and even snow in.
No need to be alarmed as it keeps everything inside,so you just need to clean it.

I "think" this works as long as you drive below a certain speed,
otherwise more air force will cause the dirt/water to fall into the center hole and drop down the snorkel body.
Just a though,as I never looked properly to check it there's enough gap between the plastic bowl and the metal cover...

Have a look at the Donaldson site
The Top Spin has a paddle which spins the dust which enters at the bottom through angled vents like the old bowl type. The dust is driven to the outside wall by the centrifugal force and outa vent

It is a replacement for the bowl type which does not need cleaning.
