Forum:
I have just had a look in the engine bay of my recently purchased hijet 993cc just to get a general idea of the condition of things like the oil, coolant and air filter etc. I was left a bit confused after following the ducting from the airbox forwards (away from the engine) to find that it branches out in a Y shape - and more confused when it became apparent that both arms of the Y terminate at dead ends? One end is moulded closed and the other seems to finish butted against the chassis. Thus there actually appears to be no route for the air to enter the airbox, which shouldnt be possible.
Have I missed something?
Air intake
Looked at my manuals and i don't have any sections on this. Mine's a 1.3 efi. Just went out and looked at mine and I can't see this either. Can't see what's going on underneath without gettin my clothes dirty. I don't think it's a concern though, it's the design (I think) :?. Show us some pictures so we can compare our vehicles setup to yours.

Thanks for the reply, I'll
Thanks for the reply, I'll see if I can get in around it for a picture to try and show it better. It isnt really a concern, it just made me curious since as far as I can see the motor runs without the luxury of an air supply
Ok, think I got it...
Although mine is a 1.3 and therefore likely to be different to your setup, I went out and had another look tonight. You know that part of the pipe that seems to end at the chasis? See if you can stick your fingers into the end of it. It should be a hollow end!
ie. the entrance to the air intake that we're looking for.
Mine has a section of air intake pipe that runs into a seemingly dead end at the chasis, just like yours. But that is the entrance where the air enters.
Let me know what you find.

Canadian... eh!
The intake
It looks on your picture like its jammed against the chasis. Mine sits out about 1/2". See if you can re-adjust yours by pulling it up a bit. Is it possible that it's fallen down against the chasis?

p.s. Put a picture of your van in the images section for us to see!!!
Right, after a bit of
Right, after a bit of fumbling around I found that the pipe was infact plugged into a round hole in the chassis, revealing that the metal beam is actually hollow. So the air is drawn inside the beam which must have an opening to fresh air somewhere underneath. Well that's one part of the little mystery solved, I do still wonder what the point is in the other pipe that is moulded closed though.
I have also added a picture of her in the gallery, she's a bit rough around the edges but serves her purpose well!
Air intake
The moulded pipes that appear to serve no useful purpose, are to stop induction roar as the air enters the engine, and also to act as a sort of 'reservoir' so that there is always a large volume or air in the intake system.

Took a few pictures, not the best quality but I think I can show what I'm talking about.
Here you see the airbox and the intake ducting branching out into a Y towards the front of the van (one to the left and one downwards):
This is where the pipe that takes the left turn leads - a dead end:
And this is the other branch that turned downwards at the splt, it simply stops when it reaches the chassis:
I find it very strange, when I followed the route forward from the airbox I expected to find some sort of funnel to scoop the cool air into the engine. It makes me wonder how the engine is getting air?
