HELP.....removing PCV fittings on a 1995 Grand Cherokee Limited
 

I have a '95 GC Limited with 4.0L I6. I noticed a fair amount of oil in my
air filter, as well as smoke coming out of the oil dipstick tube, so I
wanted to check the crankcase ventilation system to see if I have clogged
valves or lines.

However, I cant seem to pop off the front & rear PCV fittings from the valve
cover. I tried the ole "twist & pull" maneuver, but they seem secured in
there pretty tight. How do I remove these things? I was able to pull off
the hose from the rear PCV fitting and there was a decent amount of manifold
vacuum, but I need to check the orifice inside the fitting to see if it's
clogged with sludge.

I'm tempted to just pop these fittings off with a big straight-blade
screwdriver and muscle power, but I'd like to avoid damaging a $25 fitting
if I can help it. I checked my Haynes shop manual but it doesnt offer any
instruction on how to remove these things.

HELP!

You might want to go a head and buy new grommets, as they turn hard
over time. Maybe replace some of the hose that clog, and take a drill
and hand ream the orifice at the base of the throttle butterfly:

How do I remove those grommets? I twist & pull them, but they wont come off
the valve cover. Any ideas?

They break out with a screwdriver or whatever, that's why you
should have new ones ready.
