There's no mention in the Camry's owner's manual or
scheduled maintenance guide about PCV valve replacement.

Wikipedia says, "Typical maintenance schedules for gasoline
engines include PCV valve replacement whenever spark plugs
are replaced."

The '06 Camry Maintenance Guide mentions to replace spark
plugs at 120,000 miles or 12 years, and to inspect the
engine valve clearances at that time, but no mention at
all is made of the important PCV system that recirculates
blow-by fuel and water vapor from the crankcase to the
intake manifold en route to the combustion chamber
for re-burning.

By the way, iridium spark plugs lasting 12 years is great.
I remember my old Dodge Colt needed new plugs every couple
years or so. I guess that's one of the advantages of having
iridium and also having a Direct Ignition or Distributor-less
Ignition system. I'm getting into this car talk.

Not sure I'll be able to resist changing the spark plugs
for 12 whole years, though. Maybe 8 or 10.

Is it possible that the PCV is not a V at all, but a simple orifice?

Back in the olden days, the PCV held a ball on the inside and a calibrated
spring. These days, the PCV is just an orifice and does not have a
maintenance schedule.

PCV = positive crankcase ventilation so there is a "V" in a PCV system.

Yes, it is possible that there is no valve in the positive crankcase
ventilation system, not sure if the 2006 Camry has a valve or not.

There are two easy ways to check - follow the crankcase ventilation tube
from the throttle body to the engine and look for a PCV valve, or look in
the factory service manual.

Do it every 30K miles, along with the PCV grommet. Many cars only call
for "inspections." These valves can still click but do not work as
well as new valves.

Now the crank is open to the intake hose through the vent hose, but
how some of these still can get over pressurized is beyond me.

Jeff, you're a very smart man who knows a lot about cars, but it
looks to me like the '06 Camry's PCV valve does have a moving part
inside (a valve), so it's not just an orifice in this model :-)

Judging from a diagram in the Emissions section of the Camry
service and repair manual I downloaded from CamryStuff.com , the
moving part looks more like a cone than a ball. But I know
there are both types. The diagram is on Page 1,500.

For other beginners like myself, since the PCV valve is not
the empty type, it's possible it may wear out over enough
time, and it might be a good idea to change it with the
spark plugs every 12 years, or 8 to 10 years if you
wanna jump the gun a little bit like me.

I just saw John's posting. I'm sure following his suggestion
would be a very good idea, too.

Older Toyota did use oirfice valves, but I don't think any late model
car does.

These things like to gum up over time, and spray cleaning has been
recommended against. There are cars without a replacement schedule and
the valves check out according to instructions (clamp hose, listen for
a click; shake valve, listen for clicks; blow in both directions etc
etc) but still do not work.

The fact is, a PCV valve and grommet are cheaper than an oil change.
I'm just saying do not wait until the seals leak because of an over
pressured crankcase (even if the vent hose is supposed to be open to
the atmosphere it still happens).

Older ones dont have a pvc valve just an intake hose to the valve cover

Jeff, I actually should not have conclusively said that the
'06 Camry uses a valve in the PCV system. I think most of the
Genertion 5 Camry manual documents available at CamryStuff.com are
from the 2002 Camry, and although the '06 Camry is also
a 5th Generation Camry, there are some minor differences between
the '02 (first model year in the 5th Generation) and the '06 (last
model year in the 5th Generation). I guess the '06 Camry is
considered Generation 5.5 with the '07 Camry being Generation 6.

There actually are a few documents at CamryStuff.com that are
specific to Generation 5.5 (the '06 Camry), but most documents
there refer to the '02, which is very similar to the '06, but
again, there are some minor differences. So you might be right
after all! Hard to say, though, without spending a lot of
money to buy the '06 repair and service manual.

All I know is the Camry's official '06 Owner's Manual and the
official
'06 Scheduled Maintenace Guide I have at home (in hardback edition)
don't mention a thing about the PCV valve or system.

Judging from the responses here, I will take a guess and say the
'06 Camry does use a PCV valve in the PCV system. We would have
to examine an '06 Camry to say for sure. However I'm not going
to remove my car's PCV tube to find out until it's time to replace
the spark plugs, which is still years away. No use in accidentally
breaking something that ain't broke yet :-)

You do not have to remove the PCV tube to see the PCV valve because the PCV
tube is connected to the PCV valve. In other words, the valve is not inside
the tube.

Open the hood, look for a black hose about the diameter of your little
finger between the valve cover and throttle body. If there is a PCV valve,
it will be sticking out of the valve cover and the hose will be connected to
the valve. If there is no PCV valve, the hose will be connected to a
fitting in the valve cover.

Use an oem pcv valve if you replace it.

The '06 uses a PCV valve. It is threaded into the valve cover. It is

OEM valves are competitively priced. Make sure the grommet gets
chagned too at the same time.

I do use Fram PCV valves but not their oil filters (for those I use
Purolator PureOne or Bosch Filtech).

Absolutely. A PCV valve and a grommet is about $5-8. Try changing out
any over pressured engine seal for that price.

I've never seen one, I only broached the possibility. I was searching for a
reason why they would not present a replacement interval in the Owner's
Manual, and if it is just an orifice, that might explain the omission.

I spoke to a Honda mechanic about the PCV valve on an '05 Accord. Basically
there is none you have to worry about servicing. I forgot exactly what he
said, but I think he said it was metal and there was no maintenance
timeframe on them. He's never had to change one.

Some vehicles don't even have them anymore. e.g. my Ford pickup has the
valve cover directly vented to the air filter housing. Wierd but true.

(my '55 Stude - engine is basically a clone of a '63 Avanti engine, but
with the '55 water pump/accessory drive - has the same exact setup,
except the oil pan itself is what's vented, but there is also a PCV
valve connected to the carb base.)

Yeah, I heard newer engines are doing away with EGR and PCV valves.
Some don't even use throttle plates in controlling accelerations
anymore.
