Check part number 17130-PC6-003, Valve Assy., PCV This part is found in:
Accord from '83 through '87

Check part number 17130-PE0-003, Valve Assy., PCV This part is found in:
CRX from '84 through '87
Civic from '84 through '87

Check part number 17130-PK1-003, Valve Assy., PCV This part is found in:
Prelude from '88 through '01
Accord from '90 through '02

Check part number 17130-PM3-003, Valve Assy., PCV This part is found in:
Civic from '88 through '91

Check part number 17130-PM6-003, Valve Assy., PCV This part is found in:
Civic from '92 through '00

And so on. The fact that the most recent use I found of a PCV valve is
due to the fact that my Honda EPC (Electronic Parts Catalog) is from
2002, not because Honda stopped using PCV valves. Also, don't run out
and buy parts according to the list above, it is just a small sampling
of the 46 results I found for PCV valve, several different part numbers
were in use on the same model in any given year.

Keep looking, it's there!

The other way around. The Helm service manual for my '94 Civic list a
PCV valves for all trim levels, but only a select few have EGR valves.

Indeed.

The manuals at http://www.honda.co.uk/owner/workshopmanuals2.html cover various
seven models of 1984-1997 Hondas. The manuals are supposed to be identical to
Helm manuals, as Honda publishes both. Every one of these manuals discusses and
describes the PCV valve in these 1984-1995 Hondas.

For example, w_tom should see

http://www.honda.co.uk/owner/Worksho...b200/12-21.pdf
(1984-1987 Civics, carbureted)

http://www.honda.co.uk/owner/CivicManual/pdf/11-109.pdf (1995-1997 Civics)

If, incredibly, he's not satisfied with this, he can go to
http://www.hondaautomotiveparts.com/...catdisplay.jsp , inquire about
most any Honda model he wants, click on "Breather Chamber" or similar, and he'll
see a drawing of the PCV valve's location as well as the PCV valve price.

www.autozone.com likewise describes how to change the PCV valve, though it has
free online manuals only for pre-1996 or so Hondas.

I've got a 1994 Civic DX that I just replaced the PCV valve for, so
obviously that's not one of the ones in your garage...

Nate

Caroline properly cited Hondas that use PCV valves. PCV are
not used in carbureted Hondas and in some earlier fuel
injected Hondas. Furthermore, those PCV valves are not
obvious being located on the intake manifold rather than on
engine valve cover.

If a PCV valve becomes stuck open, it does not adversely
affect engine performance as PCValves would do to carbureted
engines. IOW many Honda mechanics don't even bother looking
at the PCV except if engine idles too high. PCV rarely create
failures and are so difficult to get at.

According to shop manual, PCV is something only inspected
every 60,000 miles or four years. Replaced only if seriously
stuck closed or open. Unlike PCV found in 1980 non-Hondas,
the PCV no longer creates engine (fuel-air ratio) problems.

you are mistaken...

1984-7 Honda Civic, Carbureted - http://tinyurl.com/5g5zs
Item #11 is the PCV valve

1984-5 Honda Accord, Carbureted - http://tinyurl.com/4asq4
Item #20 is the PCV valve

1986-9 Honda Accord, Carbureted - http://tinyurl.com/5anyy
Item #18 is the PCV valve

1985 Honda Accord SEI, early fuel injected - http://tinyurl.com/6zo2m
Item #20 is the PCV valve

as bush has discovered, merely chanting that it is so does not indeed
make it so. please stop insisting on this lunacy. thank you.

Try this one - 1981 Accord. Does IT have a PCV valve?

this is irrelevant. you had stated...

> injected Hondas.

as I noted earlier, pcv valves could be found in carbureted accords from
84-89 and in carbureted civics from 84-87. pcv valves can also be found in
the 85 accord sei which, to the best of my knowledge, was the first accord
with fuel injection. your statement contradicts the facts. it claims that
all carbureted hondas did not have a pcv valve. this statement is simply
false. now, had you made the statement that carbureted hondas prior to 84
did not have a pcv valve, then your statement would have been correct.
however, that's not what you said. it's not even close.
