Crankcase vent is different. Here's how I think it goes...

OBD-1 B18 has a vapor/oil separator box on the back of the block, with the PCV valve attached. Then there's only one fitting (to intake) on the valve cover.

Your OBD-2 engine doesn't have that separator box on the block, so it needs both lines coming from valve cover.
