Looks to be just some kind of protection or insulation.
Why? I have no clue.

Yea just something for dress up. If you look closer to where the pcv goes into the valve cover you'll see it's the same size as ours.

It's just a generic insulation kit, probably a dealer add on in a hotter region to get more $$ from a buyer.

every r/t and Acr i have ever seen, has that cover over the pcv hose. They also seem to use a rubber hose, and not the hard plastic line like base models have.

mine isn't hard plastic line.

the breather tube is, but not the pcv tube.

Definitely just a cover/wrap. Pretty obvious if you trace it near the valve cover.

My ACR had that too. The tube gets quite warm, so I believe it's just a thermal/abrasion sleeve.

The thing is, it gets heated from the air exiting the VC, not neccesarily from outside heat. The air temp comming from the VC is going to be pretty close to oil temp, I would think, since that's whats flowing the most in there.
I'm not sure why they want to insulate it. Not like the oil vapor is going to cool and condense in that short run.

Meh, it's just one of those "WTF were the engineers thinking that day" mysteries.

^Yeah I agree. If it was important they would have kept it. Probably something they thought worked but decided it wasn't worth the extra x-amount of money to keep it in production.

Acctually, it isn't just the oil temp, but heat from the aluminum manifold. It would carry a lot of heat up that tube. I removed the cover off it a while back, and if you arm came in contact with it you would know pretty quick.

I think it's a CYA thing.

But remember, the manifold is sucking air from that tube not pushing air into it, (unless there is boost involved).

So manifold temp does not come into play unless you want to consider heat soak. The heat is comming from the cyl. head.

But since it's been a while, we'll let you knock some of that rust loose.

It only gets worse with age, not as old friend.

EDIT:

Ah, but I do want to consider heat soak. Drive two Neons (one a Magnum and one non) for the same amount of time. Park them and take a reading of the manifold temp. Or better yet, touch them. I'll wait......

Hmmm. Why does the Magnum manifold make your skin smell like BBQ?

All I know is that they get very hot, and so does that tube.

So neener neener neener *waves cane in someone's general direction*

Careful! My bones are brittle!

Yes heat soak does pwn an aluminum IM.

OK, I'll be gentle. (Where have I heard that before?)

Trust me, I was quite surprised the first time I encountered the heat on that tube. While it isn't as bad as I made it out to be above, it does get hot enough for some no-commonsense-having idiot to seek compensation from Chrysler for his or her discomfort.
