What's the correct air filter for my van

Cheap is rarely best, just use steel or aluminium or even copper pipe, b@q sell it

 

To be honest it wasn't cheap . or at least it was £12.50 for 2 meters of stainless steel tubing with the 7mm outside diameter that fits the little rubber t piece , i searched high and low for any suitable tubing without gain , except for flea bay , I never thought of B and Q though , suppose i live and learn , thanks for the tip.

 

The stainless tubing came today , this will enable me to complete the job, i have borrowed a mated small pipe bender to assist , this will be needed because as far as i can work out the rubber T joint that fits in the roof of the engine bay is formatted wrong , i would have thought a 7mm straight through and a 5mm T of it in the middle , but is a 7mm to a 5mm , then a 7mm T from it .
should crack on with this at some point over next couple of days.

 

Did you ever get this finished?

Looking at replacing some of my missing bits, so keen to see your outcome. Cheers.

Hi. Yes i got the right bits from all over the place . The main filter was from the autojumble at a VW show, if i remember right there was a number on the filter , i put that into google and the reply came back exact match for my twin port 1600 . It already had bits of tubing i needed to attach to oil filler . I remember i got a rubber T piece that cost more than the filter . And it seemed to be a reducing T but in the wrong direction . Its not on the van at the moment as i will be removing the engine soon for a rebuild hopefully over winter . Other than this theres not much more i can add unless you want to know something specific .

 

Cheers. Yeah I have the oil bath filter so no probs there, but the t piece is broken and not connected to anything on the roof of the engine bay, someone has removed the piping to it from either side. I have the condensers in the air scoops, so lucky there!
The T piece seems to be about £6-7 at JK/eBay, it's the metal bits of pipe and the Flexi hose that I will need too.

I also have the metal pipe near the spare wheel area, so it is the piping to the t piece and to the air filter that I need. Cheers.

You could use brake line as an alternative.

 

Well! Looking at my air box set up, i have the oil bath filter, fairly original.
I looked at the air box and where the spigot should be to connect the fuel tank breather to the inlet tube (another project), there was a brazed piece of metal filling the hole.

Worse than that I realized (after reading the Haynes manual) that the cold feed tube has been cut off, with a blanking plate brazed over!!
Also, under the brazed spigot there looks to be a crimped tube (pic3). Should that be connected to something?

Why oh why would someone have done this scorcery!? Will this just feed hot air into the intake? TIA!!

It could be the hot air flap part broke, and the owner didnt realise the cleverness of the system. As in original condition it feeds hot and cold air at the right instant. And because they knew how to braze they fixed it the only way they knew how....

Hi there. Thanks for the reply and the video. I can't recall seeing any electrickery going to th casing, I presume there must be some sort of heat feed sender?!

Its a vacuum feed from the manifold via a thermo switch on top of the air cleaner. Your setup is very hacked.

 

Great!!
