    Does anyone know and can tell me where the PCV valve is located on my 1983 GT EFI? I can’t find the darn thing anywhere. Must be hidden pretty good! Thanks all!

    There's not always an actual valve so it's technically not a "PCV" that you're looking for - which further makes it hard to find/identify.....

    There's a bung on the valve cover who's hose goes to a black plastic box or cylinder (one of the many parts that varies between different Ford factories) that Ford refers to as an oil-separator between the valve cover & intake manifold. On the other end of the separator there's a hose that goes to the intake somewhere for the intake vacuum to draw the oil vapors through it. This is the same system Ford used on the 2.3 OHC/SVO.

    Here's the more common rectangular separator as seen on many/most 1.6 EFIs and ALL 1.6 Turbos - this is the same one used on other 80s Fords like the 2.3 OHC/SVO
    It is a little left of the upper intake manifold

    Here's an example of the less common cylindrical separator
    It's just left of the upper intake manifold Screen Shot 2020-05-25 at 12.44.34 PM.png

    Wish I could tell you more about the cylindrical one and the rectangular one but I haven't been able to play around with my Turbo yet (has a damaged rectangular separator) and the 1.6 EFIs are almost as rare that I haven't seen a whole one first hand yet.

    Sadly these machines are quite old so it's very likely that the original one was replaced or bypassed. My one broke after 100k and only 15 years so I bet there's few left haha

    Interesting. The later 1.9s don't use anything like that, and seem to have no trouble with their PCV systems. Maybe you could investigate one of those and use its working parts in a 1.6?

    Those are only in 1.6s and OHC/SVO 2.3s
    Don't believe any of the 1.9s use anything like those.

    But I think the 1.9 CFI and 1.9 carb use the same oil separator as the carb 1.6 but can't use the EFI ones on the carb motors without replacing the air box with something else.
