Need to know what's broken and maybe how to fix it ? Post here

As there is no 'ideal' location for the 200 Tdi air filter housing on a Defender Tdi conversion, I've come up with the 'mad' (I say mad as I can't find anything on Forums about other people who have done this!) idea of trying to graft the box-like 300 Tdi air filter housing into the front left hand side of the engine where there's lots of space.
I intend to fabricate a simple mounting bracket that will bolt onto the top of the timing cover (the 'unused' bolt holes where the air-con is fitted I believe). The picture below kind of shows where I want to fit it.
The orientation of the inlet/outlet ports on the filter housing however are almost 180 degrees away from where I need them to be and it's not just a simple job of turning the unit round and I don't think it would fit then.
It's a fairly basic paper filter cartridge on the 300Tdi and I was wondering if I could simply pipe it up back to front ie. use the air inlet port as the outlet and vice versa. Does anyone know if this is feasible and is a paper filter such as this one manufactured to only take air in one way?
Answers on a postcard or preferably on the forum
As far as I am aware, you may swap the inlet and outlet of the air filter housing without ill effect. However, the standard inlet comes in at he bottom of the filter for a reason. If any leaves etc got sucked in, it will drop back down to the bottom of the housing when the suction reduces. If the inlet is now on the top side, the leave etc will remain there and restrict air flow.
However, this can be avoided by 1) more regular check on air filter 2) place a net with gaps of not more than 10mm at the inlet (eg. snorkel cover).
Another possible issue will be water. If water gets into the housing, with the outlet into the engine being higher, there'll be less chances of water ingress. However, this issue will no longer be valid if the water is over the bonnet....that'll cover the whole air filter housing anyway. So, if a snorkel is also fitted, this is not an issue at all.
Apart from that, dont see why it shouldn't work.

Additional though is that if a small amount of muddy water (say a couple of cupfuls) gets in, then with it the right way round there is a good chance of your filter staying dry while it exits through the little drain - the same situation with a top entry will leave you with a sodden filter and possibly a covering layer of slimey-wimey stuff blocking it...
As I have often said - bottom entry is best
Mark, I have bought one of these http://cgi.ebay.co.uk/landrover-defender-air-box-air-filters-brandnew-/180610069859?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item2a0d32f563 for mine, they are the same as the military use on the 300Tdi wolf. The one I got has the twin filters for desert use. You can just see how they mount on the right hand side of the engine on this rather sorry looking wolf.

The beauty of this is a standard wolf snorkel kit will fit.
5/4 of people admit that they’re bad with fractions.
This looks like it is the right sort of clamp for the wolf filter.

From the offside wing inlet the pipes go pretty much straight across into the air box mounted on the bulkhead and then the outlet comes forward on the near side of the engine.
The air box is mounted with it's longest side against the bulkhead and the inlet is on the left hand side as you look at it from the front of the car in the middle at the bottom and the outlet is on the right hand side on the front top corner.
The platic box is attached to the metal bracket that mounts to three bolts on the bulkhead.
Hopefully that makes some sort of sense.
I'm googling for a picture, but can't find one yet, and my scanner isn't a flatbed one so won't scan the book - sorry.
