Does the 1992 2.3l 2wd pickup have like a oil drain line for over flow or anything? The reason I ask is b/c There is a tube that is running down to the pass. side motor mount on my truck. It has alot of oil there. I thought I was the oil pan gasket but I think its from this tube. Is is supposed to be attached somewhere? I runs from under the intake manifold area down to the motor mount.
