    First off, thanks for reading and all the help. It is located just above and toward the driver from the oil filter. Has a rubber elbow and what seems like a hard inner tube. The elbow is split and you can hear the air flow. Causing sporadic idle and stalling. Not sure of part number or even name and purpose of part. Thanks again all.

    Can you possibly add a photo? I'm not that familiar with this particular model but if I can get a look at the tube I can probably tell you what it is.

    I dont have and havent worked on a DOHC escort, so dont know the topology. On a SOHC LX escort it would be a part of the positive crankcase ventilation tubing, or the tube from the intake manifold to the fuel pressure regulator.

    Sounds like the PCV elbow. Does it attach to the intake manifold?

    What Gamer92 said. It's a common failure point. I think you can get a replacement piece in the "help" section at the auto parts store for it.

    With the 2nd gen PCV elbow, a short chunk of 3/8" fuel hose works pretty well.

    Is this what leaks? If so,Dorman 46027 is what you need

    it is easier to replace if you take the complete hose off. may as well replace the one on the other end too
