    Default Toyota Camry's PCV valve

    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.

    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.

    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 don't have a pvc valve just an intake hose to the valve cover

    Use an oem pcv valve if you replace it.

    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).
