Great info! I've not replaced a PCV system yet so forgive my ignorance. Are you suggesting that I don't have to order a PCV kit - just order the hose, elbows and clamps you suggested?

Thanks very much for your input.

You would wind up buying most of the kit - minus the two long hoses you are going to be substituting.

That would be the separator (PCV box) itself, the hose that goes from the separator to the top of the engine, the hose that goes from the separator to the engine block, and the hose that goes from the bottom of the separator to the oil pan. You'll also need the clamps for those three hoses.

The other items you will need include an intake manifold gasket, and if you want - throttle body gasket, an oil dipstick tube o-ring where it goes into the oil pan and an oil cap gasket for good measure.

This is what I ordered last time I did mine. Use OEM parts ONLY for the three hoses!

1271988 PCV Oil Separator Box
8653339 PCV Hose "A"
1271653 PCV Hose "B"
1271654 PCV Hose "C"
9146266 Intake Manifold Gasket
976561 4 ea. Hose Clamps (PCV)
988026 2 ea. Hose Clamps (PCV)
977964 2 ea. Hose Clamps (PCV)

You'll be substituting your upgraded hoses for the other two longer hoses.

No doubt you will probably find other vacuum lines around the engine in questionable condition. Great time to address those as well.

There's lots of info on here on how to do the PCV system replacement. Plan on the full day if its your first time.

I chased a very similar oil leak on mine for a very long time. Your pictures look exactly like the bottom of my car once did. Once I redid the PCV system and mod to upgrade to the larger diameter hoses, all the leaks stopped.
What mod did u do. You have pics?
