    I have a stain-not really wet but a stain-around the base of a line that comes out-goes into my exhaust manifold (98 suburban 5.7 2wd).
    It is on the drivers side almost on the firewall.
    It looks like a coolant line, but I haven't really tracked it to where it comes from.
    Any chance it is just some part of exhaust gas recycling? Doesn't really look like it, but??
    I think I still have a coolant leak.

    If it's a big metal hose with a heat fabric coating, it should go from the driver side exhaust manifold up to the upper intake. That's part of the EGR system. Sounds like it's leaking exhaust.

    Thats it.
    Hmmm guess I shouldn't be surprised- 14 years old-deserves to leak
