D2a TD5 - my Provent 200 installation

Just a FWIW, I highly doubt a snorkel makes a damn of difference to dust ingestion, it'll just increase the time before maximum dust loading is reached.

What seems to matter is the sealing, most panel filters for the TD5 seal poorly and dust gets in around the edges, and the media itself obviously makes a difference.

I try to convince myself that dust couldn’t get past the oily intercooler[emoji37] anyway I agree re the filters .... I’ve found that Mann Filters have a generous cushion seal that fits tightly into the airbox base.

Mahle are good as well, I do recall many years ago that there was a suggestion the discovery 2s that had a bullbar fitted had the front of the plastic shield trimmed in the wheel well where the bullbar met it leading to dust getting forced up into the inside of the guard.

IF that is correct...IF.... then of course a snorkel would assist in providing clean Air to the filter box.

Then there is the original td5 filter box, it's an unmitigated disaster. And the filter itself needs a mesh screen behind it to stop it flexing.

Most td5s that I know of that were dusted, left home one morning fine, and in the space of a few hundred metres on the rd, went from great operating condition, too knackered.

Most seem to fill up with muck UNDER the filter , and then all of a sudden either the filter ruptures or moves away from the sealing lip, the whole lot gets sucked straight into the motor, usually number one piston, and Houston...we have a problem.

Cheers
James

Yep, that's all I'll use.
When I picked up the D2 it had a Ryco.
Lots of dust up the inlet tract and a crap seal in the air box, slightly undersized.
I went straight to Suttons in Alice and bought a genuine filter for the drive home

Lucky I have an custom made waterproof box that doesn't let any dust or water in

I think that over time the the foam bits on the filters shrink. I had the same issue with a Mahle and replaced it with a Ryco, last Saturday. I had trouble closing the box as the Ryco was slightly oversized. (Maybe they just made them bigger)

After having D2's,i thought that could be the case as well,the intercooler oiled up any dust.
Maybe i was dreaming.I used an extra strip of foam on the air on sealing lip, and grease around mine which did help.

In fact,when the D2 was first released,i read an article about one of LR's first trips with a heap of petrol ones in Africa.
Mobil tested the engine oils they were using and found they had a lot of Silica in them.
One would have thought they would have modified the airbox.But i don't think they did[bighmmm]

With the 200series LC,there are continual issues with dusting engines,one of the turbos cops most of the dust due to the design of the intake/intercooler pipework.Some engines have been destroyed,many blame aftermarket air filters,that don't seal as well as the genuine ones.

FWIW,the D3/4 have a brilliant airbox that seals very well.

Most everyone obsesses about the 'best' engine oil but it's dust/dirt ingress that shortens the life of most engines.
No engine oil can mitigate for dust (or fuel dilution)

Hopefully!
They might even be sourcing them from Mann now?

All filter companies source non core lines from other manufacturers and that can change over time

which begs the question how come the aftermarket industry didn’t produce a better air filter housing if it was such a known problem. After spending a lot of money recently on old Chaffy the last thing I want is another dusted engine.
