On the rhs the carburettor pre-heater riser looks pretty good



But on the left hand side, it looks like an aluminium cover is missing, the jubilee clip doesn't look OG, and the area is covered with soot



Does anyone have a spare missing aluminium bit ?

Any theories as to what he jubilee clip is for would be welcome too !

Thanks
 
I agree. It's likely the pre heat pipe has maybe rusted through and the clip is to cover the hole. With the clip on there it might not have been possible to get the cover to fit back on.
 
Also, the aluminium piece is not original.
All tinware is made of steel.
There are some pieces of tinware that go in that point but these seem to be missing from most engines. Next time I'm down the garage (Saturday?) I will dig out the pair I have (sorry, they're going on my engine, not spare) and get you a photo.
 
Thanks George

You're absolutely right - it didn't occur to me the aluminium bit was not OG - but looking at it it does have a home-made look about it and I can see the proper part on my wife's Beetle with the nice asbestos (?) seal.

Could you see on yours if both lhs and rhs are the same...?

Many Thanks

I don't think the 2 pieces of tin are identical. They might be simple reflections of one and other but either way, I doubt they are interchangeable.
 
Many Thanks - since routing around my tinware I've found a few bits missing - one that could be important is the short tube that ducts hot air from under the car to the flexible tube that feeds the air filter.

Been reading about Bernoulli's principle, apparently he predicted carbs freezing up hundreds of years before the car was invented.

Also missing the bit that goes in front of the pulley - but that doesn't seem to do much - maybe safety....

The "hot air pick up pipe" can only be used if you are running an original oil bath air filter. In all other circumstances the hole in the rear tinware should be blocked off.

As for the other piece, it depends what you define as "in front" of the pulley.
When you open the engine bay you are at the back of the engine.
If you are referring to the piece that sits "above" the pulley, then this is just a guard piece and is not strictly necessary.
 
I am running the standard airfilter - so should have the pipe - though the bus has run fine for a couple of years.

No really surprises about the purpose the jubilee clip - looks like a replacement manifold in the near future - might try 2 jubilee clips to keep it going till winter

Are the "new" manifolds any good, or would I be better off getting a second hand one



Thanks in advance for any comments...

I would find a solid used manifold, make sure air passes through easily at both heat risers. If it doesn't, make a loop heavy gauge wire at a length that will reach halfway into your manifold and spin with a drill until clear of carbon build-up. Flushing it with kerosene during the process will help soften some of the carbon. It's surprising how much can come out of those little tubes. Buy used/order new tins & 3 piece gasket sets for the base of heat risers ... they are mirror images of each other.
 
Hey man I have a couple of og single port intake manifolds.
Will take pictures tonight if you're interested.

Is the gasket material between the parts above asbestos?
I just scraped all of this out and put new Wolfsburg West gaskets in, they are too thick so couldn't connect them up with the tin below, but are held solidly in place by the single screw on the cylinder shrouds and pressure from the heat riser tube.

Good Luck

Hi 70-CA-Panel,

I would be very interested if they've got plenty of life left in them. Looking at various pictures it seems some manifolds are one piece (ie mine), and others have join mid arm about under where my coil is. Are the two types interchangeable ? What are yours ? (are the two part ones dual ports ?)

{{No idea if the white seal material is asbestos - coming from the 60's, in a heat blocking capacity, and looking white and flaky it could be}}

 
Hi Matt,

Yes the joined ones are for dual port heads, I have two single port intake manifolds like the one in your picture above.
I'll take some photos for ya.

Andy
 
Hi Matt,

Here are some pictures of the two manifolds I have.

The black one has a vacuum port and has been blasted and powdercoated. The aluminum has been bead blasted as has the pipe above. There is some light pitting on the heat risers but the pipes are clear.

The other one has been stripped and has surface rust now. There is no pitting on the heat risers but they are fairly blocked.
