CCV valve cover vacuum hose sizes??
2000 XJ Sport, owned for 10 months, 4.0L.
Today I noticed a leak in the 19/32" hose from the CCV elbow closest to the firewall (I replaced both of the elbows and their grommets <1k mi ago) and goes to the intake manifold. When I removed the old hose, I found that the brass nipple on the manifold was not 19/32", but closer to 11/32". The PO had inserted another line into the 19/32 line to attach it to the nipple on the manifold.
QUESTIONS:
1. Is that the correct size nipple on the manifold?
2. If so, is there a reducer connector that goes from the 19/32" hose to 11/32" nipple?
3. If not, what's the correct size of that manifold nipple?
As always, TIA for your help.

PS: I can take some pics in the morning if that will help.

Are you referring to these ends? https://www.oreillyauto.com/detail/b/dorman-help--4422/belts-hoses-16454/hoses-25069/crankcase-breather-hose-14015/df8b1723839a/dorman-help-valve-cover-breather/47128/4528370/2001/jeep/wrangler?q=Breather+hose&pos=2
You can just search for a breather hose and replace the hole thing as well. It, obviously, would be the most expensive route.

I am going to need a better description or a picture cause I am thinking you are asking about the elbows on the
hard plastic lines that attach to the nipples on the intake manifold.

Might be worth it to just buy a whole new set of hoses.
