Difference between Euro and USA M117 4.5L engines.

G´day mates,


I´ll be Down Under X-mas 2018 (!) for some gliding, sailing and other stuff (XXXX).
So I can offer my shipping-services from QLD to NZ if required If there is any chance for me to hop over (e.g. accomodation?), I´d be happy to deliver things personally

Best regards,

Markus

If she finds someone to swap those parts (don't forget injector and ignition distributor?) in NZ that would be great. Otherwise shipping is already expensive.

The engine has the blue Bosch 036 injectors. Don't know about the distributor.. If it is different from a 4.5L USA or 3.5L Euro distributor, perhaps that is another way of confirming it is the 8.8:1 engine?

Is the vacuum advance/retard system different for the 4.5L euro vs the 3.5L euro? Different advance curve? Hopefully the distributor is the one that came with the engine.and it has been adapted properly to the original vacuum system.

An owner in Australia has a 73/74 4.5L euro parts car and is checking if he has the needed parts.

Hi Graham,
yes also iggnition distributors are different. You find correct one in attachment A of my compendium.

Looks like both 4.5 & 3.5 had retard & advance in 1974. But just how car is set up is another thing! Timing could be another thing that is off. Hard to be helpful at a distance and it doesn't seem they can get much help in New Zealand.
MBUSA Classic could not tell me which engine it was from engine number! But I suspect that being RHD engine, it must be a Euro.

Hi Graham,

yes also ignition timing is different. And I am not surprised that MB USA cannot tell you what kind of engine it is.

Hi Graham,
hi Volker

aren't the piston bottoms of the USA and Europe M117 engines different?

Then a quick insight through the spark-plug-hole using a endoscope-camera would help to identify the engine.

'Obelix' will know the differences between the engines ... maybe I remember the differences were once listed in the sternzeit-107.
