Just saw this online and found it a bit interesting:
Could Honda have any further over engineered it?
Although its made like that (the vacuum schematics) for the Double fuel-delivery system
(one for the extra-rich initial combustion chamber
and another for the lean main combustion chamber)


At least its not bad as an FD (Mazda RX7)




Runner ups:

Ford's variable venturi and CFI

Chevy's electronic feedback Quadrajet

Chrysler's lean burn

and any carburetted 80's japanese import with wires

 

Hello fuel injection!!!

 

The FD is still bad for a EFI vehicle

 

Yea, if I had an old civic with a vacuum leak I'd junk that bitch. With an FD hello LS1

 

Phil goes to Casey..."Hey Casey"
Oh no you don't be touchin mah Arr Ex Seven with one of those blastid LS swaps ya hear"

 

Thank god we have the Vac-U-Tec machine nowadays

yikes!

 

my 89 fuel injected accord is pretty damn bad too.

i have a vacuum related problem with the brakes..yikes.

im hoping its just the master cyl.

 

My jetta's vacuum lines are easy as pie

 

LOL, I remember when i worked on my friends 86 civic with that same bullshit. Lets just say it lost about 30lbs in vacuum lines.

 

i think thats the same as the carbed 86 1.5 motor i did a head on. that was a bitch getting all those vacuum lines on and correct

VV carbs are EVIL, I was just tinkering around with one in my freetime once and thank god I never had to work on those things when they where the norm in dealersihps. The late 70's and early 80's where a dark time for mechanics indeed.

 

it coule have been worse, the B20a3 with 2 carbs, i countes over 64 vacuum lines when i started taking **** apart

and yeah, it was confusing as hell, i had a vacuum leak and refused to track it down

 

lol thats crazy compared to a mid 90's B series which has like three vacuum lines

I think it does use only three... one for FPR, one for EVAP and... i can't think of any more.

 

It looks pretty straight forward to me... But I am Japanese to

lol yea thats about it. and "EK's" use a vacuum controlled cruise control IIRC

 

I've changed my mind after looking under the hood of my 84 prelude... V Lines suck

 

holy ****..

 

Early emissions controls + lack of reliable, sophisticated solid state controllers (ECUs) = lots of vacuum lines.

Keep in mind what the state of computing hardware was in those days. Hint: RAM numbers had a "K" after them . . .

 

to bad your in cali you could just devac the thing and bring it down to 3vl at least that is what i did on my carb'd 1500 crx

 

webber carb conversion FTW!

Funny, the CVCC motor in 79-82 Accords was called the EK1. Also, all of the older Hondas have a vacuum motor for the cruise control. Maybe all the newer ones too.

And if you ask me that RX7 diagram looks a hell of a lot simpler than the CVCC one. I've removed the vacuum nests from both of my old Accords, and boy was it fun.

Uh yeah:
