    Question PCV Valve

    Does anybody make a PCV valve with a 45* or a 90* outlet? I know I need to purchase the molded hose or whatever is available for my MGM; just would be nice to use regular fuel hose or something in a pinch; without kinking it.

    Doesn't that fitting come with the valve?

    Yes, but it's a straight fitting. If I use a regular hose and bend it towards the throttle body; it kinks. If the PCV valve came with an angle, it would be much easier to deal with.

    Strange as my OEM PCV came with both. That is why I asked.

    I think Packman is asking for his '05 MGM, which looks quite a bit different than what I'm used to seeing on a Box/Aero/Early Whales.

    Rockauto listing for '05:

    vs Rockauto listing for '98 (same as Box and Aero):

    ~ 1991 Mercury Grand Marquis LS "The Scab" - plenty of rot, backup/summer cruiser
    ~ 1997 GMC Yukon SLT - wannabe winter DD - many issues, returning sometime in the 2020s
    ~ 1991 Mercury Grand Marquis GS "The Ice Car" - Rotting Retired Winter DD
    ~ 1989 Mercury Grand Marquis GS - Rotting Retired DD

    When did Ford change the style for the PCV valve? The one for the '98 is the old style; like what you would find on the Windsor engines (pushrod variant).

    Yea, I was referring to the Box part and/or '93 through '95. Not sure about anything newer than that.

    It looks like the last year for the Box style PCV was 2002. 2003 and 2004 are similar to 2005, but 2005 has that electrical connector (some sort of sensor I would imagine.)

    I believe the connector is for the heater. Both my 09 P71s had heated pcv valves. Kind of strange being they were originally Florida cars. Maybe after 07 Ford made it standard on its fleet panthers.

    My PCV has a 90
    None of the RA pictures are showing the actual part.

    The part comes with a twin port elbow. Pull the plastic off to use as single straight port, plug the skinny port to use as single large 90.

    They went to a heated pcv valve.

    Packman, got some 1.4" copper pipe? Make your own 90ishº elbow.
