70 series cruiser air filter leaking dust

Pity it is too small to read!

Had same issue with gunuine Fiat tractor filters years ago, swapped to Donaldson = problem solved
they recon our dust is beyond some of the european filter specs as they have very little dust and no where near as fine ads ours

I find that very dissappointing that Toyota have said that, as dust is an enemy to diesel engines.....we don't except that in the mining industry and servicing the air filtration sytem is top priority as a dusted engine is very costly for us.

As a result I am very fussy about my own engine in regards to oil, water, fuel and especially air......and even more so because it has a turbo.

I absolutely agree with you...it should not be happening.

Remember though despite what you and I as the end user thinks most manufacturers consider a vehicle life to be 5 years, especially the Japs as anything older than that is nearly impossible to register in Japan.
Toyota obviously consider that it can ingest that level of dust and make it to 5 years, if you want it to last longer then might be worth adding better filtration. Oiled foam will let more through than a Toyota filter though.
The original round Toyota filters that used to be fitted to all cruisers were very good at keeping dust out, I fitted an oiled foam element to two 70 series and both showed dust traces like your photo's, went abck to genuine paper elements, no more dust in the inlet tract. The foam filter was oiled by the manufacturer so I did nothing wrong as far as that goes.

Your photo shows more dust than I would consider to be normal. I share your concern.
