I was wondering if my pvc hose should have a crease where it bends at

Should it look like this ac delco part number 12556932

Part number 12574660 I think it might be this it has something in the middle of the hose u can see it in the pic on the end so that the pcv valve can connect to it

Looks like it got folded inward/ bent there. You could take it back & ask for another one.
I suppose you could straighten it out, and use electrical tape to strengthen the bend, and even add another piece of hose over top & tape it again.

it'* the original hose I was wondering what hose is right in the pictures posted above

Both look almost the same, I'd go with ACDELCO 12556932 as the bend looks better, the other one looks to have a similar crease as what you already have, just not as a defined crease in the bend,

Before I order the pic with the ac delco part number 12574660 what'* that plastic thing in the middle because part number 12556932 doesn't have it and how do I take the old hose out with out breaking something

In your pic it looks like the PCV valve plugs directly into the hose, I don't see that smaller plastic thing that is in the pic of the GM part..
Does your old hose have that plastic piece?
If so I'd just try wiggling it, or if you had to carefully slice into the hose, of course I don't see the plastic thing in your pic, just on the GM part pic, so I am not sure how to advise you, can you get a pic of your hose showing the plastic piece that is in the GM part pic?

Oh I see now, the black plastic part is on the other end of the hose/


If you can remove that from your old hose then you can order the ACDELCO 12556932, if not go for the GM Part since it looks to have that plastic piece already attached.

Ok thanks it looks like that part in the above pic what'* that part number

Welcome, that is the part number 12574660 that you posted.
