More on filters

Had my turbo deisel 80 series serviced at Berrima Deisel Service last month. I had a K & N foam filter and they said to bin it and put in an original as they perform a lot better in the setup I had, snorkel, turbo deisel, etc. Might be worth your while to call them and find the full reasoning behind binning the foam filter. Can't see the reasons would not be similar on your Disco. He suggests strongly putting a pre filter on as well. I am thinking I might look into the snorkel inserts as suggested by Kev in post 4092. They are only $46.50 for a pack of 3. Says they are serviceable, I guess this means you clean them like a normal foam filter and then oil, etc? Would be good for general use, then go the full blown pre-filter (Donaldson?) for really high dust areas. Again (thanks Kev):

Used a finer filter foam pre-cleaner sock over the snorkel of my 110 on my trip around Oz. Certainly helped on the dusty sections like cape york and the gibb rv rd. Left it off on the highways.

A lot easier to clean than getting the filter element out. Given the amount of gunk accumulated on the sock, I'm sure it was effective in precleaning.

Yes you can get paper precleaners..

The Sock things, mate uses on his GU 3.0, and he likes them, to me precleaners are just another restriction.

If you check your filter daily on a dusty trip you should have no problems.

You seem to want foam, so go with what you like. What works for me maynot work for you , Kev, Colin, Dave, Fred, Jim etc... ;-)

YMMV.

As we are talking about checking filters on a regular basis(sometimes daily). Don't forget to loosen off the clamp on the rubber hose that goes from the filter box to the inlet. You can then pull the filter box top off and not have to bend the hose. Constant bending leads to cracking which could lead to water getting in. Even if the water (or dust) does not get in, the hose costs a small fortune to replace especially if it is a toyota.

i have to say im all for foam filters was shown a test with the paper filters where you remove the metal caps from the paper of your old filter & you can see where the dust has got through via gaps in the glue that holds the paper on , i have done this on a few of the paper filters &most have at least one spot where there is a gap in the glue which has alowed dust through. but having said that it is not aparent in all of them.to me yes the foam filters do get dirty quickly & are a bit of a pian to clean but i would rather a dirty pain in the ass filter than a dirty pain in the wallet motor

I have a good mate who is a diesel mechanic, 25years Cat mostly earthmoving. He reckons that the foam only filters bricks. The OE filter has a specification check that and ask any aftermarket manufacturers what theirs do before you fit them
