Do anybody know where I can find the elbow that connects the line to the PCV ?

 

If you are talking about the one that fits into the back of the manifold of the 5.4 liter, O'Reillys has them. BUT, my Ford parts lady told me there were two sizes so make sure you have the old one out for comparision.

When you post a question, please remember to put down the year/displacement/etc. It make it easier to help. Good luck.
