Isn't that just mercury's pinto? It's a 2.3 right, should be the hose coming out of the valve cover. It's been so long I can't remember that one might have a tube coming off the side fo the block.
you need to replace what is called the PVC valve (positive crankcase ventilation)
it should be plugged into the valve cover into a rubber pocket and cost about $4.00
I may guess the valve cover is blue?
