  1. My 2.0 Fi has this "tube" by the offside heat exchanger. Its a US spec motor and I understand its a cold air feed to ...something

    I assume there should be a pipe to join it to here..

    ...any one got the right answer - my guess is Joker will!!

  2. its the heater dump tube, when you have the heaters set tooff the flap inside the valve directs the air through this tube and away from the engine. its a 79 only part and yes there should be one on both sides, I am missing both of mine
     
  3. Cheers pkrboo, I only have the offside - will look for near at autojumbles ! Is the connecting pipe steel or an ali corrugated tube?
     
  4. not entirely sure tbh, i thought the pipe just went straight on, but it could have a bit of fexi pipe to join them
     
  5. What pkr says, I don't think it's a necessary addition so you can do without them. I might have some in the shed but quite crusty
    :)
     
  6. Thanks both - if you have a nearside one Joker I'd be interested!
    As they are not essential its not whats causing my fast running when warm - so back to the drawing board with that!
    Cheers

  7. Well thats' not correct, the pipe is a exhaust from auxiliary BA6 petrol heater that would be positioned under the floor of the van. Check under, it might be still there.

    I will be intrigued to know myself. I thought it was the exhaust for the espacher. I was looking at a bus a friend has in at his place that has that pipe but his isn't a 79. And is that 79 stateside only or for Europe too?? I've not seen one before.
     
  9. Any chance of a couple more pics.

    I think a Ba6 exhaust exits in front if the rear tire. As it Is in the centre of the bus. The Bn4 exhaust exits out the back but it has more of a bend on it
     
  10. Couple more pics then -
    ...from the side

    looking from front to back at the end of the pipe by the side of the HE

    Looking like heat dump to me - no sign of an espacher or and sign of where one could have been attached in the past..
