On the elbow, go to Advanced Auto. On their floor shelves, not behind the counter, is a PCV elbow marked for Ford ($10). It is too big on the end that goes to the PCV valve. I just cut off the old elbow at the PCV valve and spit on it for slight lubrication(cause it's tight!), and pushed the new one over that old piece.

That Damn PCV hose elbow is terrible! Mine was soft and had a large rip in it, and it was full of sludge.
