The TD5's have that in the airbox too. It spins the dirt out of the air, which then drops out through the duck bill.

Slunnie, Erich's already stripped down a few Td5's and I don't believe he found this before. Was it something that went in late in the Td5 Defender and carried over to the Puma perhaps??
You're explanation is reasonable and may well explain why the air filter stays so clean.
I cant see how that can work very well, those blades look as tho they would be stationary, and the distance to the filter housing is not far..
I think that would be more of a restriction than anything else...
But I have been wrong before..
I will see if mine has 1 and might remove it to see if there's any noticeable difference..
Cheers Ean
You are right Simon, the TD5 Disco does have this and the V8 D2 doesn't. Also the TD5 Disco has a duck bill valve and the V8 Disco doesnt have one.Quote:

Memory lapse on my part some D2's are the same, not the sort of thing one looks at often. :bangin:Quote:

Diesel 4x4s often have a higher spec filter assembly than equivalent petrol models.Quote:

Probably not a good idea to remove it if driving anywhere dusty.

Computational fluid dynamics (CFD) is one of the branches of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the millions of calculations required to simulate the interaction of liquids and gases with surfaces defined by boundary conditions. Even with high-speed supercomputers only approximate solutions can be achieved in many cases. Ongoing research, however, may yield software that improves the accuracy and speed of complex simulation scenarios such as transonic or turbulent flows. Initial validation of such software is often performed using a wind tunnel with the final validation coming in flight tests.

im 99% sure that all deff td5s pumas have that in the air box,
also you say the starter is easy to get out,;);):mad: iv done about 6 starts on pumas and td5s are way way easyer,, like you say heaps of hoses and the body is very close to the stater, thank god for ratchet spanners,
Given that the engine is out, this would be the ideal opportunity to give us a couple of shots of the EGR. Any other shots I have seen are taken from a downward angle through all the pipe work. A clear unobstructed shot from the side would give a better idea of the EGR area and make it a little easier to suss it out before I have to dismantle it. I know that you are busy with this project but it seemed too good an opportunity to pass up. Inspirational post to say the least - just might give the lawn mower an overhaul this Winter!
