Hi All

Have seen this on an unrestored car…does anybody have anymore details…? I assume the 022 refers to the 1.7L but what about the other number?

Any insight would be appreciated…thanks

@JeffBowlsby .

The tech page is from a training manual from 1975.
correct?

that names a A and B version of the EC engine.

and in 1975 there was a difference in the cars for cali and the other 49 states?
cali cars had cats. (min?). egr. etc.
was this equipment on 49 state cars?
i remember reading that cats were phased in stateside due to supply chain production questions. so cali got them first in 75 and rest of america next in 76.

so my proposition is A and B in 75 are because there is two different versions running concurrently. one for cali and one for 49 states.

go back to 74.
i can find no evidence anywhere in anything technical that there is anything other than a USA wide approved 1.8. California and 49 states.

but there is an A and B version.
the stickers you have prove that.
does not mean they are concurrent?
could mean they are chronological?
an engine bay can car is going to have the port on the rhs of blower fan opened up for the hose to the can.
a frunk car has the port on the lhs for the can? i think.

whats the date on the EC-A sticker car? do you have it.

just another thought.

i mean in my game A and B versions can mean a lot of different things.
there is an A and B version side by side.
and there is an A and B version one after the other.

its blowing like a gale down here so i got nothing better to do.
apologies.
the roof is probably going to come off my building soon. (IMG:style_emoticons/default/sad.gif)

i believe what you are saying is right.
the A and B thing is due to emissions changes or differences.
my thought is that for 74 its chronological.
they shift the can.
its big enough to warrant an emissions approval for variant a and b.
but both versions meet california and all states - as cans are in universally and have been for some time.
in 75 its concurrent?
there is a california specific variant and a 49 states variant? don't know. you would.
what are the stickers like in 75?
do they state 49 state specific only (if don't have cats and not sure about that anyway) unlike the 74 stickers which do say meets california and all states together.
