Tipo (Classic) After many modifications and lots of TLC:

It looks like I over engineered it.
Here's a couple of pics of one from the Argentine Tipo forum:
Just a plain box with the filter sitting in it.

oh!

that's interesting, about the pollen filter...

I recently bought a filter from eBay for the 146 (which seems to be an identical ventilation plant) as the picture showed it in a frame, which looked like it would fit the intake, above the fan.

However, when it appeared; it was just a large filter, like an air filter, about the size of a piece of A5

Interesting subject. I orderered a part shown on Eper for the Tipo. As you can see it is designed to hold a cartridge filter and appears to resemble the equivalent hole in the scuttle. However annoyingly the unit is too high to fit in the space available !

Looks nearly right, jonti, but maybe this is closer, it appears to be a lot slimmer:
Parts Nº 20 and 21:

Thanks for your help with this. Mine was part 4641214 so different again. It wasn't cheap so rather than risk it I may look for one off a scrap alfa 156 as they look to have the same arrangement and there are still some about.

They're far from being cheap.
When mine needs a new filter I'll make one to that pattern, it will be easier than the one I made.

crikey!

'how deep does the rabbit hole go?!'

Those guys in Argentina fabricated that from galv steel. Looks like a piece of electrical trunking lid.

Ooh- you've really got the hooks in me now for a result.

Did you ever have the water cover for that intake SFB..?

Of course and I've discovered how to remove and refit it easily.
The top comes out last, but goes in first.
Here's a pic of Tommo_2's, dare I say poorly fitted one.

And mine.

Right-

Yeah: that looks about correct.

I think I'm going to try for a filter frame that drops inside the mouth of the intake.

I need a good morning with access to metalwork stuff at work, but with the car scuttle panel removed at the same time.
I've had some major clear outs in that area before- in Scotland; you don't want the leaves and damp collecting in that spot. I taped up the intake aperture whilst washing it all out.
The 146 & Tipo are identical in this respect...

Over complicated and harder to seal off.
The Argentinian method is much simpler and does the job.

Over complicated ? Maybe

Harder to seal off? Let's find out...

I always think; how would it have been done if it came out of the factory...

Admittedly: I've got a tendency to pursue over complicated solutions..!
