Thread: series2aair filter

if your using original equip it is prob an oil bath type air filter, NIL element required. the oil will work better than the K&N. Ive got an old one you can have. it will require a good tidy up and a new flexible hose. its free if you want it.

HI i'm in Adelaide so I will need to arrange to get filter here but I will be really gratefull to have it. Thanks again Steve P

Actually, both will be pretty average.

I have a modified hilux housing in my IIA.

The series oil bath aircleaner must be about the most tested filtration system ever fitted . It works very well for the purpose and engine it was designed for and is very cost effective , esp if you use your old engine oil at oil changes to oil the filter , adds to the eco nature of landrover ownership JMHO

It is certainly COMMON on old equipment (with low tolerances, etc...).

When oil bath "filters" were developed, much of the modern knowledge about how filters work was unknown. Air filter theory wasn't developed until the 60's and 70's, and even then, significant advances were made in the 80's onward, and are still being made today.

The oilbath filter is a cross between an impinger and impactor/cyclone. I am sure that below about 40 microns (depending on engine speed), it would be useless.

You won't find a single piece of offroad equipment fitted with one of these today I am sure. They all have cyclonic pre-cleaners and 1 or 2 fibrous filter elements.

One of these days I will have to test one to put all the misunderstandings to rest.

I thought you were going to a year or two ago?

I would think that a worse problem on the earlier Series engines is the rudimentary filters on the engine breathers - these vent straight into the crankcase, and rarely get serviced anyway!

I thought about it, but haven't had the time as yet. If I had thought about it beforehand I could have tested one when I did the other test.

Breathers usually only blow out, so I don't know if they are as much of an issue.
