Question

on the 4.0 on the valve cover there are two hoses, one being the crankcase vent tube. what is the one located in the back, it looks to just be a round piece with a vaccum line going into it...what is it and where can i get it? also, is the CCV a dealer item because i can't seem to find anyone at the parts place that knows what i am talking about. thanks in advance.

The larger tube inthe front of the valve cover is inlet air to the crankcase. The small line at the rear is vacuum. That is the CCV tube -- the Cherokee 4.0L doesn't use a PCV valve to regulate flow.

A couple of weeks ago someone posted NAPA part numbers for the CCV tubes. Try a search.

I got both the hoses on the rear for like 12 bux from the dealership.

Yeah, the small vaccum hose in the rear of the valve cover is part of your CCV system.......the hose and grommet are available as a set at the Jeep dealership.....about 12 bucks here in Oregon......when I replaced mine, the CCV orifice was nearly completely plugged.....although I buy a lot of parts at NAPA, their books only showed a PCV system on the 4.0s....go figure

my '91 has one, but it's an HO. All the auto parts stores' computers said no but i picked one up at the stealership for like 6 bucks.
