I was thinking the same,but under the filter,the air on side,the lip is very small,hard to get the foam to stick to the lip.I recon a few real small g clamps around the edge of the filter box holding the top & bottom of the air box tight together would be the best option,but hard to engineer,i will keep thinking,as said air box design is extremely poor.

Also if you push down on top of assembled airbox,you can feel it squeeze up tighter.

You could also screw the top & bottom up tighter with sef tappers around the edge of the assembled airbox,but is a bit bodgie.

Oh well, I'd better put that on the "to do" list also. The other thing which I'm thinking, is to use a V8 box also, as they have no duck bill which partially devalues the snorkel. Actually, no hiclone also, so it will breath better.

Do we know if the v8 airbox seals correctly?The hiclone thingy may also be there for a reason.
The other thing i am thinking is that the actual pressure in the airbox in the diesel may be lower,therefore increasing the issue compared to a petrol.I could be wrong here as i am no mechanic any ideas?

I would have thought that the sealing is the same between the V8 and TD5 - I'm pretty sure (perhaps incorrectly) that the top half of the lower box is the same. I would also expect the TD5 would have a lower pressure in the box due to the hiclone and I would assume the TD5 pulls similar or more air when on boost.

The hiclone spins the dust out which drops out the bottom.

Dusted motor:mad:

Yes I too have had the dust on the wrong side of the TD5 filter. My LR specialist put it down to poor workmanship (ham fisted) by the previous service person. My box was distorted. Replacement box was about 3 c notes. Was also advised to use a snorkel to reduce the damage when the problem happens again as where the air is drawn from currently is one of the dustiers options they could have chosen.

I've also still got the wire mesh still in place pre-MAF, so any bits of foam that could get through that would be minute...

Went to ormeau yesterday for a play,Son took his navara,his mate came with his Pootrol tray back,the last of the td 4.2's,has lockers etc.It was real dusty.We checked downstream of all air cleaners when we got back,both Nissans were perfectly clean,disco was dusty:(.Before we left i had put more grease around the air cleaner seal,and also on the o ring near the maf grill....

Today,i cut up some real thin strips of foam,which is sticky on one side,and stuck it to the lip on the bottom part of the air box.I then fitted the air filter into box,greased the top rubber seal on the filter,and then fitted the top of the air bix and clipped it all back together.

Should of got photos,but forgot all about it.

The grease i used my brother gets from work is silicone,waterproof,non melting,they use it for sealing on vacuum systms,it never runs,which is good.


Anyway i will see how it goes,and let you know.

Just thought i would revive this thread:eek:

This is what i did before a very dusty cape trip.I fitted thin strips of foam to the lips on the bottom of the airbox,that the rubber air filter sits on.This makes the airbox top clamp on tighter.I also put heaps of vacuum grease on the top rubber seal of the air filter & also along the part of the top of the airbox that seals on the upper rubber seal of the air filter.

I also had a safari snorkle fitted.
The difference was amazing,no dust on the inner airbox top,just a very slight coating on the guard in front of the MAF.
Also one airfilter did the trip easy,last trip,same sort of distance,not as dusty though,used two air filters & they were completely clogged.

Hopefully the problem is now solved:)

Am kicking myself though,should have had a snorkle fitted years ago.:(
It not only reduces a massive amount of dust that goes into the airbox,on dirt roads,it also gives you a lot more confidence going through deep water crossings.

I recon the original air pickup in the inner guard,on the D2,picks up dust from the front wheels,which isnt good.

Would you be able to post a photo ? - would like to replicate your seals
