1977 Westfalia correct engine parts

[palmgreen57]

Hello
Just bought an original september 1977 westfalia bay window
I'd put this 1600 engine back to 100% factory original specs.
I can't find official press picture or brochure showing it
Anyone could help, what's not correct ?
I guess coil, fuel pump, carb
I'd like to see also how the right way for fuel line around carb and pump
Thanks for your help

My advice is to remove the inline fuel filter.
As the trick here is to have as few connections that could fail and spray fuel over a hot engine.
The fuel pump looks correct and the coil is roughly in the correct position.
The oil pressure switch is disconnected which I believe is the loose wire.

Yours is a European bus as some did still come with the type 1 engine.

sure my thought was to remove this filter as I already have one fuel after the tank
the coil is not in the correct position but I can't see any others way to put as earlier engine
the carb is an empi repro, I'd have a 34 pict 3 from what I know
do you know where find vw pictures of 1600 bus engine ?
thank you

Hello,
what about my fan shroud ? look like early round 30hp style, I guess I should have later style more squared ?

[heyskull]

Could be from an earlier bus.
What is your engine code?
It is a 47 year old bus so will have had some chai.

SC

[palmgreen57]

it's a 1600 dual port AD code

[heyskull]

I think that is correct code AD or AS.
I can see by the riveted plate this is a remanufactured engine.

SC

[heyskull]

AD code is a 1971-1973 engine code.
AS as what yours should have in it is 1974-1979.
Basically the same engine with 50bhp power output.

thank you for the informations
I think this dog house style fan shroud is a repro and I'd have a "squared" one

[busdaddy]

Yes, the shroud is wrong, it's a repro some install for that "vintage" look. Many of them lack the internal vanes for proper cooling, any later dual port shroud will be an improvement, although a proper bus shroud has a larger scoop for the oil cooler air supply.

It appears your vacuum connection for the brake booster is coming off the left intake manifold outer end, instead of the original one on the intake center section right below the carb.

That vacuum nipple looks tiny, like 4-5mm, most likely for the aircleaner preheat on a beetle. The Bus manifold has a 12mm nipple in that location.

Most European 1600cc buses did not come with vacuum/power brakes.
At least all the 1600cc ones I have seen in the UK do not have a brake booster.
Check whether you have a brake servo.
