Default Changing Plugs - '93 JGC V-8

It has probably been 40 years since I have changed plugs on one of my
vehicles. Primarily because when I was working I never kept a car
long enough for it to need new plugs. My '93 JGC V-8 has 90,000
miles, and it is time for new ones. I thought I would just do it
myself so I bought a set of plugs. Then I had second thoughts and
checked with a couple of independent shops, and they both wanted $60
just for the labor! The Jeep dealer wanted even more! Am I missing
something here?

I know on my '67 GTO you had to put it on a hoist, remove the front
wheels, and go in through the wheel wells. The JGC looks pretty easy.
Maybe the air cleaner tube needs to come off, but other than that, I
can't see why it would cost $60 to remove and install 8 spark plugs.

I see that there are little metal sleeves around each plug, and the
plastic cap has a ridge that kind of covers the sleeve. Is it OK to
pull on the ridge to remove the plug wires? Or do you need a special
puller? Can you just leave the metal sleeve in place and take the
plug out through it? Thanks.

Hi Dick,
I think you're looking at the electronic fuel injectors. Like an
'93 should still have a distributor with with ignition wires running
down to the plugs next to the exhaust manifolds.

Hi Bill -

I can see the injectors between the valve cover and the intake
manifold. These are definitely the plug wires coming from the
distributor, and going between the valve covers and the exhaust
manifold. I could e-mail you a picture if you want.

No thanks, I know what a 1957 318" looks like:

It was your description that threw me "little metal sleeves around
each plug, and the
plastic cap".

That is not a 1957 318". I don't even have to look in the book for that
one.

Hi Earle,
I believe the engine you're thinking of is probably the 318 using
the 383 block with the irregular shaped valve covers, but I know of the
318 that topped out a 360" unfortunately I can only find an engine
picture going back to this '67 Plymouth:

Let's see:

Check gap - 1min
Pull old plug - 5 min
Install new plug - 4 min

Total 10 min/plug avg. X 8 plugs = 80 min. Labor rate in my parts $50-70/hr,
so $60 bucks for labor sounds reasonable to me.

I doubt you will be able to do the job yourself in under an hour on an I6
let alone the V8 if you haven't done it in 40 years. And that is without
losing 20 minutes trying to find the damn spark plug wrench that should be
right there in the tool box that your neighbor "borrowed" 2 years ago,
dropping any wrenches or plugs into god-awful places where the sun never
shines such as skid pans or those "metal sleeves" you mention, no beer/butt
breaks, no time lost trying to locate the aft plugs or removing shrouds and
chunks of engine that don't even look familiar because they weren't around
40 years ago, and no breaks to stop for bleeding/first aid. I can't even
change a fuse any more without 2 days of back pain!

Hi Dana,
You need to visit the pit area of a drag race meat, they rebuild a
seven thousand horsepower engine less to time then you're giving Dick:

Ninety percent of the engines I've worked on have always need at
least the spark plug ratchet: http://www.billhughes.com/sparksocket.jpg
