D15b3 vacuum line question
Juan-Pierre Herboth
I recently bought a 95 Honda ballade(I'm from South Africa elsewhere
its called a civic)
1.5 16v carb.
I recently replaced the timing belt and noticed a vacuum line that
have been blanked off.
It is part of 3 branches. One comes from the air intake to the air-
filter, the other from the
distributor housing(I assume it to be the vacuum advance) and the
blanked off one. They all come join up and seem to enter the back of
the engine (possible the carb).
My question is that I would like to know what this blanked off line is
for. I see that
there is what looks like it could be a connection on the distributor
cap, but I'm not sure.
I didn't get an owners manual with the car, I was able to download one
online, but its
for International models and does not include the carb model and thus
I cannot
determine what to do with it. The car drives fine, but I would like
things to be working the way they were designed to.
Kind regards

Photos? We haven't had carbs on Hondas since 1990, so your setup may be
different from what we ever had.

maybe the online usa versions dating back to 87 or older will show it.
here, the civic went injected in 88, but i understand that with other
markets, the technology only crept in slowly - for instance, in europe,
they kept carbs for a generation longer than us, then as we went from
throttle body injection to 4-point, they got the throttle body injection.
worth looking.

you can't directly, but you can load them to a photo sharing site, then
post the links. tinypic.com works just fine.

advance is seperate,so the blanked off line is joined by the one from
the air intake and then into the whole 'manifold' of connections
joining up.

the one from the intake, i.e. north of the carb, is just vent not
vacuum. anything south of the carb is real vacuum. thus, i'd guess
that the blanked tube and the distributor cap nozzle are supposed to be
connected - in a lot of cars, the distributor cap is so vented to
[theoretically] reduce moisture condensation.
but don't take my word for it - find the manual. if you bought the
spark tube gaskets from your local dealer, try them and see if they will
let you look at their manuals or microfiche.

your posts are really f-ed up. google groups for posting is a /really/
bad idea. download a /real/ newsreader, and sign up to one of the free
text-only newsgroup servers on the net so you don't keep on polluting
this group with multiline whateveritis. please.

The vacuum line with the screw in it is for the air-cleaner heat-riser
valve. If you're in a warm climate, you can just remove that vacuum line
entirely and forget about it. Just make sure the riser valve is CLOSED
(look or feel inside the air-cleaner snorkel: should be clear through and
not blocked).
Notice the exposed pipe under the valve on the snorkel? That should go to a
heat-stove on the exhaust manifold, but the corrugated connecting pipe is
missing.
The supposed vacuum line on the distributor cap is just an air-vent. Leave
it alone.
The "vacuum line connects to branch" photo is taken from too close-in. I
cannot tell what's around it.

take a better one.Regarding the corugated pipe, this is my 2nd Honda
and both had the same snorkel on the aircleaner and a similar pipe on
the exhaust manifold cover.I assumed that it could be for colder
climates to pre-heat the air.However on both Honda's thats missing.I
guess since we here in South Africa generally have weather never
goiing below 10 deg C that we dont make use of that.Thanx again

That's correct. It's to help vaporize fuel in the carb when the temperature
is near or below freezing.

Where you are, you don't need it.

nah, it's an icing thing. important in a moist cold climate.
/essential/ with ethanol fuels that contain their own moisture.
