Dont want to refit the 200tdi air filter box after rebuild

greyhair · Jul 21, 2016

i all
I am almost at the end of my rebuild of my 1992 200tdi defender 90
and looking at the engine bay i wanted to do away with the large airfilter housing
my thoughts are fitting something like this

but what would be the best way to incorporate the cyclone breather pipe ?

lynall · Jul 21, 2016

You could just route it to atmosphere, I did the this with my tdi into series conversion, the engine is well worn and does eject a little snot from the breather pipe, I have also done the same with the defender, just ran the pipe over to the inner wing under the servo, not a drop of oil or oil mist.
I did try an oil catch tank on the 90 and they seem to generate their own ecosystem of water and snot in large quantities.
I would guess yours being rebuilt wont make any mess at all.
Obviously no good for serious off roading due to the possibility of water ingress.

Thank you Lynall
will have a look at doing that

Put a tee piece in the hose after your filter. I think I used a water tank plumbers fitting.
Unless your directly coupling to manifold.

I'm no expert here by any means but I would prefer to keep mine standard. I suppose it also depends on how your going to use your Defender. A friend who has a 300 tdi modified his air filter to some supposedly top johnny filter. He as done several trips to Morocco. On the last one his engine blew in Spain on the way back. The Defender was relayed back to the UK where it was put in for repair. The verdict was the air filter did not filter out the dust which caused the engine problem. He has since reverted back to the standard filter.

Oil bath filter is what you want for dust, anything else wil clog up or pass the dirt/sand into the engine.

The yanks do some sort of test involving running a make of filter for so many miles, removing it and then wiping around the inlet stub with a clean white cloth to see how much dirt has passed through the filter, apparently one make in particular left the white cloth filthy guess the make, begins with a k!

Cone-type filters allow the engine to breathe better for the simple reason that don't filter air as well as a standard paper element does.

My series always used to have oil bath filters, and I have often wondered about fitting one to my Ninety. They are a good system, and a cheap one to run!
I haven't done so mainly because I am unsure of their suitability with turbocharged engines.

I agree, and there is no cyclonic pre filtration as on the standard set-up.

And agree with the above comments, standard is best!

Interesting read here http://www.aulro.com/afvb/technical-chatter/50650-air-filter-tests-finally.html
I would be looking for a paper filter in a standard air box.

On my Series 2 with 200tdi engine I am running the std series oil bath air filter, the crankcase breather also vents to atmosphere and there is zero yes zero oil residue in the intercooler and pipework, lots of people said it wouldnt work, naturally I ignored them and did it, 5 maybe 6yrs later its still good.

That is interesting, I might re-visit that idea at a later date!

after lots of looking around and getting pricing think i will stick the standard one back in for now
could mess about with it when its back on the road

IamRobbie · Jul 29, 2016

I don't run a filter and havnt since I've owned it. Although I don't plan on driving to morroco either

lynall · Jul 29, 2016

I change lots of filters on trucks at work and I certainly wouldnt run without one, theres all sorts of crap that comes out of them.

Turboman · Jul 30, 2016

Just changed mine a few days ago, cyclonic bit had plenty of dust in it, and the filter itself was grubby. Plenty of dust in summertime even in the UK.

I can't seem to find a decent place to fit a filter at all. Ive tried. I could do with a water proof after market unit that's small

Didn't yer motor come with an airbox, then?

IamRobbie · Jul 30, 2016

Yes as a 19j soaked in oil and got ripped out the day after purchase by my friends who said I didn't need it. I then put in the 200tdi and never found a place for one. Tried the 200tdi box from the disco which was round but it just didn't go in and sit right so I left it. Every 6 months I go out take a look then leave it be again lol

Can you find somewhere to vertically mount a 19j airbox, or even, as dicussed before in the fred, a series oil bath cleaner? Vertical fitment takes up less underbonnet room than the laid back position of the Tdi.

Possibly if I can source either
