Re: HELP.....removing PCV fittings on a 1995 Grand Cherokee Limited
Good call on the grommets getting hard -- and if he can't get them to pop
out, they're hard and leaking. He won't be able to buy just the
grommets he'll have to buy new assemblies, which includes the metering
orifice and hoses. On my `89 4.0 the vacuum line attaches to one of the
arms of the intake manifold near the head not the throttle body, it looks
like it goes to the throttle body on the 2.5L.
The URL Bill gives lists the Mopar part numbers and TJM will need them --
because no one at the customer service level knows what to call the parts.
I believe that there is one error in the URL, though. He mentions a
"valve" down inside the valve cover. When I had my cover off all I saw
was an oil-splash baffle, but I didn't try pulling it apart to be sure.
Balkamp also makes the vacuum harnesses, I got all three from NAPA for
US$41, which may be a better price than the local dealer's parts window.
They _are_not_indexed_ in the current catalogue but you can find them
by flipping through it, looking for the illustrations. They are Balkamp
part numbers 715-1365 (rear) 715-1366 (left) 715-1367 (right). Total cost
locally for all three parts was US$41.

Wow, makes me wonder how you install the new grommets without breaking them
as well? I've seen situations like this before, but why do engineers design
parts that "need" to be broken in order to be removed? Gotta be a better
way....

Yep, that photo describes exactly what I am trying to do, but why do the
grommets require such a difficult removal? My shop manual says the PCV
orifice tubes should be inspected every 30K miles.....so I am expected to
buy new ones every 30K because they cant be removed without breakage? Gotta
be a better way, right? :)
