E350- 7.5li engine, can't find PCV valve

[sassfactor4]

For the life of me I can't find the PCV valve on my E350 7.5l engine, I've looked at the diagram in the owners manual and see the general area where it should be, and the replacement piece I've bought (Fram FV367) seems to not look like anything vaguely similar to anything in that area. Is it not a normally accessible piece, or is it underneath the van? Any help would be greatly appreciated.

As I recall, they are in the RH valve cover, and do reach/see it you need to remove the doghouse (engine cover).
