After puachasing my second hand 3.0 GU patrol, I went about the usual stuff... fitting spotties, decent tyres (BF Goodrich TA's) brake controler for the camper and a dual battery system.
This is where the trouble started.
Whilst following the instructions supplied with the battery tray (ARB), I had to push the air filter box towards the front of the vehicle (gently), so that the battery tray would slide down into position. But in doing this, I accidently broke the seal between the inner guard, where the air intake is, and the air filter box. This is a flimsy piece of foam wedged between the inner gaurd and the piping into the airbox, so, obviosly I didn't notice it.
As luck would have it, two weeks later we are travelling up to
Millstream / Chichester NP through Wittenoom, where she sucked up a lung full of dust. Straight through the air filter, through the airflow meter, through the turbo and into the motor. This tripped out the ECU (the computer running the engine) which constantly kept going into "limp home mode", which I quickly came to call Limp Wristed Mode!!!!!
Basically we didn't have a major breakdown, but it was a major pain in the backside because we were about 700 klm's away from anyone who could help. Please do youself a favour and inspect this if you own one of these cars.
Even if you have a
snorkel fitted, this little peice of engineering excellence can still let
water in. Thanks Mr Nissan !!!
Long winded I know but worth the read.

That does not make sense.
Even if you rip the tube right off, all air still passes through the filter element before getting into intake.

I agree with HL here , I think its just another Nissan 3.0 with a shot airflow meter or turbo.

ARB did not design / fit the duct into the air filter, Nissan Did. And this may also happen even without fitting a second battery tray.
So much dust got into the air filter that it not only chocked up, but it actually failed to stop all dust particles getting through.
While I was at Nissan in
Port Hedland, two other guys with same problem.
Don't get me wrong, this is a great 4WD. Good on fuel, good off road and tows camper with no fuss at all. Just one little thing that should be looked out for, thats all !!
Oh and of course Toyota owners having a crack at any oportunity, but thats OK, I used to be one of those, te he.

Hello muzzgit,

You appear to be getting stuck into Nissan for their seal design, when it was ARB's installation instructions that led YOU to damage the seal.
However, I doubt the seal damage made any difference in this instance.
The main problem here appears to be a lack of air filter maintenance.
Gotta clean 'em regularly in dusty conditions............

When i fit a
snorkel, i remove all the ducting that has foam seals,a nd seal them with sealant, so as any vacuum the engine creates while running through
water will not draw
water past the seals, and rendering the
snorkel a waste of time to fit initially.
I also use one lap of duct tape around the lid / body seal of my vehicles, to help the lid stay sealed, and is easy to remove to replace/inspect element.

I like your approach, sounds like you do this a fair bit, but I don't follow what you mean when you say that sealing up everything renders a
snorkel a waste of time?

What that means is, if you fit a
snorkel to keep
water out of the intake, and dont seal the other joins in the inlet tract, then its sort of a waste of time fitting the
snorkel ;-)

Unless ive missed a point here I cant see why dust should get past the filter even if its rather clogged.

I also can't see why there a cracked seal will let more dust in than all the dust getting sucked in through the inner guard even if there was no crack. I've had to bang out my air filter twice a day in dusty conditions, even with a fully sealed
snorkel setup with the top facing the rear. If you don't like so much dust in the filter an option is to get a
snorkel with pre-filter or fit some sort after-market pre-filter (assuming the GU only has 1 filter at the moment)

Paper elements actually filter (not flow) MORE efficiently when they become dirty. They just flow less air and performance suffers accordingly. Which is probably why your ECU went into 'limp home' mode - it wasnt getting enough air flow accross the sensor. Did you see evidence of dirt in the clean side?
Servicing paper elements is a balance between airflow and filtration efficiency. Which is why most earthmoving gear uses a vacuum restriction indicator in the intake system to indicate the ideal time to service the element. Cleaning it too frequently allows dirt to fall into the clean side and also means the elment isnt filtering as efficiently as it can be. So, service it when it needs it and not before, this is one example of overservicing doing more harm than good.

After installing a
snorkel its not a bad idea to seal the intake at the top whilst the engine is running at idle. If the
snorkel is installed correctly the engine will stop very quickly from lack of air. How dust got past a normal nissan air filter or any other filter is quite beyond me. If the filter clogged totally the engine would simply stop. My previous truck, a disco did this quite often till I worked out the rubber tube was collapsing and cutting off air. Dam hard to find that one.
