Disclaimers: this isn't an anti Toyota thread. It isn't suggesting Toyota alone has potentially serious dust problems. In fact it isn't suggesting anything other than some Toyota owners should be wary if travelling in very dusty conditions.
Hope it is useful to current and potential owners. If a bun fight at 40 paces ensues - don't shoot the messenger, I'm just an innocent, if interested, bystander.

North of the Tropic of Capricorn is Toyota country.
No one drives the Hilux.
Get my drift :)

So the 200 doesn’t have a dusting problem because the maf doesn’t throw a fault? Awesome news. All those companies making custom air boxes will go broke tomorrow.

I was aware of a potential problem with 79 Landcruiser air filter boxes, Bazooka, from reading certain pages on social media. There is often some useful info there, as long as you sift out the inane garbage!

A number of people have complained about the airbox seal leaking, and intake pipe being covered by fine dust, downstream of the filter. Towards the end of a 10K km trip through WA's deserts and the Pilbara, I checked the air intake, to find it as clean as the day the vehicle left the showroom.

I changed the filter element last week, and the element would have had enough iron ore dust in it to get Gina Reinhardt excited. Maybe I got a filter system that works as it should?

My personal findings follow, 2012 altitude 200 series diesel, safari snorkel, with unifilter sock over ram head, into the bungle bungles, across water and on dirt, at the camping area, i checked the filter, and there was dust on the motor side which had water droplets on the dust. There is only 1 place water could have came from, and that is through the filter housing sealing surfaces to the element, which are plastic and clipped into tension....this unit is then connected to the motor by a snorkel concertina rubber inlet, which is quite solid in construction, resulting in the top aircleaner plastic moving when the motor torques under load (crossing a river), overcoming the clips and letting dust and water in....I now have an alloy air cleaner, and snorkel socks for dusty conditions.

I have a 2015 3L Prado, the dust finds its way through the tiny gap between the seal on the side of the filter and the inside of the air box.

My solution is to smear the seal with grease each time I change the filter, this has reduced the amount of dust bypassing the filter by 80% ??

Very little dust there now :)

I would suggest water proof grease - I have a tub of bel-ray - I use to use on motorbike airfilters. Assume they still sell it in motorbike shops but maybe not - its been a while.

I am just using an old tube of thick grease I had in the garage.

I wanted a thick one because there is a bit of heat off the motor and I did not want it to melt away.

The idea came from a discussion I had with a mechanic .

Double filter in a canister and pre cleaner on top, should be used on all fairdinkum 4bys the same as earthmoving equipment and , build all the you beaut electronics around things that have been proven for years and years. might not look pretty but who cares if it saves a engine worth thousands of dollars?,,,,,, and besides who are you going to trust to rebuild a late model Toyo engine?.....Toyota.?....Pfffft!

My opinion only


Cheers Axle.

The MY16 lets lots of dirt/dust past the air cleaner. Toyota fix was to smear grease around the seals. Not sure how successfully this is and am concerned what happens to the turbo with the dirt getting past the filter.

Also, have lots of dust coming from the passenger side behind the rear wheel. Found the trailer wiring grommet was not fitted correctly leaving a huge hole. Refitted but the dust is back. It’s hard to get to this grommet as I have a storage system and cannot get to it from under the car as it has a 3 litre compressor tank fitted.

The MUX suffers from panel blow-by too.
Outback dust gets down to 5 microns I'm told. The panel/airbox seal doesn't cope. You can see the accumulation on the engine side pipe.
A Unifilter replacement does cope.
