Air Filter & Exhaust

Could you stick with the beetle filter as this has the vacuum operated flap. Is there a reason this filter set-up wasn't used on a bus.

 

Don't fit a chromy pancake thing. They're awful. There'll be no provision for warm air pickup when the engine's cold.

 

There’s not enough height in the engine bay

 

As Paradox has replied don't think enough room in the engine bay, not tried or measured as yet as awaiting transmission return and rebuild.

 

There may well not be enough height. "Proper" Bay airbox setups do pop up on eBay from time to time. Best to get a paper one if that suits your van.

 

You might be able to find the stock T2 oil bath air cleaner with the vacuum operated flap around .. try e.g.FBI VW in Swansea.
It has been said that the fine spray of oil entering the engine from the oil bath rather than paper filter element type is better for the engine than " dry" filters .. but. It has been said without proof .

If that were the only filter in the world available I would mount it beside the engine on the filter stand then hack it a bit to run a piece of 50mm diameter wire reinforced neoprene hose to the top of the carburettor.

 

Found an oil bath filter £30

 

A or B seems to be positive & negative no matter what type?

 

Though there's nothing wrong with the workings of the oil bath filters, they were fitted to all vehicles for a long time - up to the 70's and so there are a 1001 different versions.
Only for this reason I suggest you will find a suitable one more easily if you look out for a pukka bay window 1600 paper element filter and stand. If you can find a proper bay oil bath setup that's fine but you'd need to know exactly what to look for or trust the seller does.

 

What year is your bus
Does it have a metal stand on the rhs of the engine bay as you look through the engine hatch?

 

This is the paper element one.

Still need the stand that's welded to the van.

 

It had a type-4 so no stand.

 

Engine Bay is currently empty as awaiting return of transmission so could install/tack a shelf in if needed. 1973

 

Will this filter from the Bettle definitely Not fit?

 

Type four in a 1973 is interesting I didn’t think they started using them that early.

 

No was a Type 4 previously installed, its a Type 1 now, AB Engine originally a 1300cc.

 

Mines a December 72, so 73 model…left factory with 1700 engine and auto box.

 

What gearbox do you have as that may need a different input shaft for the type one engine.

 

There are 72 model years with them too, they don't have the top hatch at that point.
