I understand that this is a vacuum/breather line, but what is the rubber connector boot etc. called specifically?

The rubber "boot part" came apart & I need a new one. I would like to know what to ask the dealer for so I don't sound like a moron.

Thanks!

 

rubber gromit

 

So, I need the rubber grommet for the ________.

My biggest fear when trying to learn about repairing this thing is my lack of knowledge & looking like a fool when describing parts.

 

thats for the pcv (positive crankcase ventilation) system.

 

There are several threads on this...this is what I replied the other day....



The Mopar name is the crankcase vent tube. The one in the front is PN# 5303 0991, the one in the back is 5303 0495. I had to replace the one in the front because I cracked it while I was trying to get it out so I ordered both of them plus the grommets they require(PN# 2946079). Total for all three parts was $21.13.

And some other mopar part numbers for all the pieces for the 2 different hoses for my 98. I guess they are the same for yours.

5303 0991--PN for the from outlet piece
5303 0495--PN for the rear outlet piece
2946 079--PN for the grommet for both pieces
4854 180-- Vent tube for front to the air cleaner box
4854 265--Vent tube for the back to the intake manifold

I had to go the dealer to get this stuff.

 

Advanced Auto Parts also carries a selection of PCV tubes. I've made one trail side before with a sway bar bushing, spark plug boot, silicone & a hose clamp, in case you don't want to go pay the stealership prices.

 

I bought mine at o'reilys in the help section. They had the grommet and the plastic elbow.

 

X 2 For the PCV valve!

 

i don't think we have a pcv valve, i think we just have hoses that act as passages for the pressure to vent into the intake system.

 

Go the the dealer like I did, and ask for the rear CCV elbow grommet. Beware, the front and rear grommets ARE different. The rear one has a small restriction inside of it, as where the front is open all the way through.

Correction above: Jeep 4.0's dont have a PCV system. Those systems have a controlled valve which monitors air exchange in the crank case. CCV systems, which our cherokees have, constantly have a steady stream of fresh air cycling through the system. The back-drop of this setup is the common rear blockage, which causes blow by in the oil filter.

 

By the way, NICE looking engine.

 

yeah we dont have a valve because it not very high pressure...btw that header wrap you got should hugely reduce under-hood temperatures...

 

Stupid question, wouldn't the header wrap cause the header to crack from the heat?

 

I wondered this too. I read somewhere that a guy bought one of those lifetime warranty APN headers, wrapped it, and it cracked.

 

No its not the pcv it called the CCV get it right so he can find the right parts.
