    I need to the name or the part number of the PCV hose that goes from the drivers side exhaust manifold and runs down the drvers side of the engine then it goes behind the engine and turns into the firewall. I guess Ford has problems with the rubber elbows leaking?

    Can anyone help me out?

    If you just need the elbows then you can use the dorman 46027 for both ends. The tube is plastic and usually it’s the elbows that leak

    I need the elbows and the pipe or hose. Does anyone have any ideas where to get some aftermarket pcv pipe or some hose. The path the hose takes is like the letter L so it has a 45degree bend in it.

    I was just working on my car today... and I don't remember seeing any tube from the exhaust manifold to the firewall. I'm a novice at this stuff, but a tube linking the exhaust to the passenger cabin sounds like a tremendously terrible idea!

    There's a tube with an elbow that is known to fail, located behind the engine kinda by the starter. Is that what you mean? Fortunately (for me) mine hasn't broken yet, but unfortunately I have no idea how or where to source a replacement should it fail.

    First picture is the close up of the drivers side front part of the engine where the PCV (positive crank ventilation) rubber elbow which is part of the vacum hose that goes down the drivers side engine then goes behind the engine and to the fire wall. In the second picture I outlined in red the route of this vacum hose looking from the front bumper into the engine bay. This elbow and vacum hose is what I am trying to find even if it is aftermarket vacume line kit as shown in the third picture.

    Is something wrong with the whole thing, or are the elbows just leaking?

    Ha ha yes somebody has used pipes (like you use on air compressors) as part of the PCV ventalation system behind the engine where it goes into the firewall. The elbow in the front part of the engine has crackes in it so I am just thinking of the best way to re-do this whole PCV vacum line. Trying to see if anyone else has re-done their PCV system.

    The picture I included are from under the car looking up at the engine. You can see the starter in the pictures. Somebody has used pipes as part of the pcv system probaly because the pcv ventalation hose is known to collapse where the hose has any bends in it from the manufacturing process. The oil residue that is found in the pcv blow by contains oil that can break down hoses over time and collapse them. Oddly enough this pipe contraption is actually working, however I don't want it to fail on me when im driving and im out of town.

    There are no ZX2 around here in the junkyard. It cant be that hard to come up with a better idea than whats currently on it. Besides a junkyard rubber hose will probably be all weatherd and dry rotted.

    The PCV starts by the exhaust and goes into the intake manifold. Under the fuel rail and near the starter.

    Based on the screenshots. It looks like the routing I described. It also has a plastic intake manifold.
