1974 914 1.8, the mystery of the EC-A and EC-B Options

[wonkipop]

i'll be dropping the information we have gathered over Dec 2021 in with a set of posts.

the material was prompted by mr b ( @JeffBowlsby ) who observed that for the 74 MY there was an EC-A and an EC-B engine. mr b's thought was that the EC-A was a 49 states car and and EC-B was a californian car for emissions.

mr b's view was rational and reasoned. 73 EA engines are 49 states. 73 EB engines are california. 75 engines are documented in factory literature as EC-a (49 states) and EC-b (california). the logic should follow?

BUT

as per the mystery of the 914, the truth about 74 1.8s turns out stranger than fiction (or common sense?).

the material is not necessary to running a 1.8 or having fun with a 14. (IMG:style_emoticons/default/smile.gif)

its for historical purposes and as information to 74 1.8 owners to assist with restoration if they want it.

@wonkipop As promised, here's the white font version; I think the text shows up much better.

"L" is for L-Jet, obviously.....

[Van B]

First off, you two are ridiculous lol...

Second, there's a reason for my numbers question: I'm wondering if we can figure out a reasoned number for surviving L-Jetronic cars. I was hoping that the vin database could be filtered by engine type, but it looks like it's not so. But, if we could export to xls and read by the remarks for 1.8's that are original FI or carbed, then we could prove out a market for companies like URO to make some replacement FI components. The AAV, CSV, and TTS are all NLA in their original form and could be easy to reproduce.

Good move, Van.
My thought is that 1.8s may be the most rare except for the two LE cars. 6-cylinders might originally on par but many rescued and many converted, leaving 1.8s produced only 15-18(?) months and many not salvaged or have been converted to 2056, as are the 1.7s that were produced 2+ years.

correct.

twice as many 2.0 D jet were made.
4 times as many 1.7 D jet.

approx 30,000 1.8 L jets in 412s
with mostly identical components.
close to zero still running?
be more 914s preserved.

all parts for this L jet version 1 would have been warehoused in the USA.
sold nowhere else.

thanks.

the red and black version is the one i love.
same as the car.

Great! Works for you so go with it. Can appreciate the “colors”.

Well, I straight up missed this page...

yep.
but the figures are for calendar years not model years.
so it gets mixed up from that point of view.

[Van B]

Not really. You said you could figure exactly the number of ‘75 models, right? So the remainder would be ‘74 1.8’s produced in 1974.

i've already done it for you mate.
its on page 4 of this thread.
got you the exact number of 1974 1.8s 10,452.

the figure was inclusive of euro 1.8s which i cannot separate out.
(you can waterboard me to interrogate the maths, its all up there for airforce scrutiny).

i got you exact breakdown figures for 75 1.8 L jets and 75 1.8 euros which i could do off engine numbers.
my kremlin source leaked a dossier on those.


steve's smokescreen of beer labels distracted you.

now you can order an airstrike on URO parts.


EDIT
a bonus for you, since i failed to provide military grade intelligence on 74 L jet numbers - and i know you want to slip some 1,8 euro pistons in yours.
glove box manual for uk 75.
respected owners enough to tell them to lubricate the distributor.
don't think those of us with USA cars were trusted to do that?
(no retard on vac can! - poms still loved NOX and pea soup fog).




check out the use of the word "bonnet" in guidance to lubricate the rear trunk lid rollers.
thats a pure bit of pommy lingo.
our USA booklets call it a rear lid hinge.
these booklets are so tuned to the language of their markets. (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/biggrin.gif)

i must admit i can still remember my mothers' datsun 180B handbook written in Japlish - which she would put in front of me at the dinner table and ask me what it meant. (IMG:style_emoticons/default/smile.gif)

@davep

i mentioned in pm that i had also seen an example of karmann rivetted tag on rhs of front trunk similar to what you brought up.

digging through files accumulated on ECA/B research i located them.

here they are. more surprising than i recalled.
perhaps you already have these examples.

1)
VIN 4742918254
K # 2019552
= mon 13 may 74 build commencement.





2)
VIN 4742918255
K # 1959559
= friday 10 may 74 commencement




cars are 1 VIN # apart.
tags gone in on the lhs on friday car and rhs on monday car.

after that date examples i have (2 weeks later and a june car) the tag goes back to rhs.
a momentary abberation.

new data
entered into tables on page 1 of thread.

05/74 low miles original condition 1.8 L jet.
VIN # 4742917931
K # 1939542 Wed 8/MAY/74

no emissions sticker visible.
2 hose tune up sticker = EC-B
distributor vac hose hook up consistent with EC-B
Sold new in West Virginia.
engine stamp = 604. consistent with EC-B, no temp gauge option installed from factory (EC-B engine with standard sump lid).
metal fuel expansion tank. (to note fuel tank was replaced with new part but original expansion tank appears to have been re-used, see original sticker). 8 may consistent with cut off date of approx may 10 for metal expansion tank.

@wonkipop I’m planning on redoing a sheet of tune up stickers. Could you remind me which ones had the single vacuum hose sticker (EC-A Caalifornia?) and which the dual hoses (EC-B non California?).
I think I need to make a scorecard sheet to keep these variants straight. (IMG:style_emoticons/default/dry.gif)

Got it! Will let you and @Van B know when they're done so if you want you can sport a correct 2-hose tuneup sticker. (IMG:style_emoticons/default/piratenanner.gif)
Just revisited the 12/25/2021 entry above which indicates the reverse (EC-A are 49 states and EC-B are California). (IMG:style_emoticons/default/blink.gif)

not sure what entry you are referring to.
perhaps @JeffBowlsby at the start of it all suggesting EC-B was california and A was 49.
jeff was using the logic of the 1,7 engines and later 75 cars.
as we discovered it is german logic of a different order. (IMG:style_emoticons/default/biggrin.gif)

EC-A = 74 california.
EC-B = 74 49 states.

its all there on page 1 of this thread with the photos to demonstrate.
and as we know our cars are EC-B and are 49 states from new.

in 75 it goes EC-a = 49 states. and EC-b = california.
not capital letters.
however that engine labelling only happens in a service introduction guide for dealers and mechanics to the 75 model. the engine emissions labels on all 75 cars is done in an updated manner that refers to engine families and engine type and no longer uses the EC format.

i do believe there is a reason that happens with the capital A and the small a but i won't go into it here. suffice to say that basically a 74 california engine is in fact a 75 49 states. hence A becomes a. and in a more complex way the EC-B of 49 states becomes the EC-b of california a year later. but i will save that up unless someone really wants to know. its just an observation rather than something you can document from any contemporary technical documents.

I was thinking about the charcoal can air supply and vapor exit lines again, and how switching them cleans up the 1.8L engine bay a bit. Might even do a better job of cleaning up the vapors. Eliminates the crossed S-hose in the middle of the engine bay.

It looks so right for all the wrong reasons and so wrong for all the right reasons. (IMG:style_emoticons/default/aktion035.gif)
