Is it coming down from underneath the flywheel? If it is, it's sounds like an upper crankcase seal is bad and that might explain the poor idle.

its comming from much lower than the fly wheel . its the lowest point in the engin housing and then running down the exterior.

You may have a loose drain line between the air silencer and the intake manifold.
