Testing Snorkels

Sounds good.. but be careful.

A guy at Volvo in Brisbane told me of a service manager in a Volvo Truck workshop in Scotland who had his "rug" sucked off his head, sent through the turbo, through the engine, through the turbo again and out the exhaust pipe.

Would have loved to see that!

I guess the filter would be your safety gate in your case.

G'day Snowy.

Just thinking about the same thing today, i have recently removed my toyo original snorkel because of a mounting issue.

I thought along the same lines as you with stalling the car, that lasted about 1 mili sec the next idea i had was to pressurise the snorkel system the with the engine off of course. After checking with safari they recommend the pressure system.

As i don't have a compressor i will do the tried and tested method of she'll be right and have a few snatch straps ready for the first crossing.

Spray aerostart around joins with motor running.Revs will rise a bit if any is getting in.

Most filter boxes have one or two water drains made from reasonably soft rubber. Blocking a snorkel will induce sufficient suction pressure to invert the rubber bleed/s and break it/them.

Separately the suction will then draw on the seal on the oil coolant supply to the turbo.

Then if the rubber feed pipe from the air filter box to turbo/or to the manifold is relatively old you could potentially induce early failure due cracking.

Would need to place lots of caveats on such a piece of advice.

Pressurising the system to say 5psi would be a better method. Soap solution on the joints and check for leaks, would be my recommendation.

1. Find deep water, preferably croc free.
2. Drive into water until it comes over bonnet
3. If engine goes BANG the snorkel needs better sealing
4. Buy new engine and repeat procedure until you find and seal all the leaks (or run out of money)

In my troopy I reckon I could seal the top off and she'd make no difference whatsoever. It is a design nightmare straight from the factory. That probably why the safe wading limit is 700mm??
