    Proper SVO PCV Valve

    This question comes up every now and then so I'll just leave this here.

    The correct PCV valve for the turbo EFI 2.3L OHC as used in the SVO and TC is Motorcraft EV-127-A (aka E5ZZ-6A666-A).

    (Yep, it really has that many sixes in it.)

    Thanks Mike, I think I am about due to purchase 3 of them, one for each turbo car.
    When I asked for one for our SVO & the TCs at the local parts stores they tried to sell me units that had a vacuum tree.

    Funny you should mention that.

    The NOS ones I have here read "W.A.P." (with attaching parts) which one might think to be the hose clamp. But no. it comes with a runner cap end to cap the non-existent vac hose nipple. And an instruction sheet.

    Any chance that you have a pic of them to go with your very detailed collection of SVO parts pics?

    Thanks for the pics Mike,
    I guess that is the kind of detailed photographic work on cars & parts that we have learned to expect from you.
    I am going to buy three of them as soon as I get home.

    I don't recall the part number, but Yes, the first production engines used a different part. You can find the part number from rockauto. iirc the upper hose that goes to the bottom of the in-line intake was a slightly larger internal diameter, but I've slept since then.

    I replaced mine recently by ev127. My car is very early production 84 (#126). Had no issues with valve, sits tight and works as supposed

    According to the Ford Parts Catalog, 83 & 84 turbocharged engines with EFI took the EV-76-C PCV valve. D9DZ-6A666-A

    That's what I was finding in my search. I need to check the PCV on my 83 TC but I know it's white and the EV-76 on my 84 SVO is black. Different manufacturer?

    Amazing how many PCV valve part numbers there are. Sure seems complicated for such a simple part.

    Thanks for the info guys.

    Since Napa, Autozone, & OReilly are all within two blocks of each other in Prescott Valley Az, I drove up there & tried all three of them today with the numbers above.
    None of them were able to correlate the numbers with anything they carry.

    Are these PVC valves only available from Ford Dealers?
