I've done searching and found some repair manuals in PDF form, but they look like they are more geared to electrical than PCV. If you just have a couple routing questions see if you can find one with the V8 on a sales lot or something and open the hood to take take a peak. If you know somebody else with a V8 ZJ see if they will let you take a couple pics. I'm guessing that from the engine install you have a couple pieces of the PCV system that you don't think are hooked up correctly.
