Yeah, it's funny. I replaced four of the six plugs with new before I went
to have it smogged (I thought I had six with me but had only four) replacing
#2 of course and when I drove it it missed, felt worse than before I did the
replacement. By the time I got through with the smog (2nd station, drove
about 10 - 15 miles) it started to even out and run smoother (computer
adjusting?). I parked it at work and later went back out to see what the
plug looked like and there was oil all over the threads of the plug up to
the base of the thread. When I took the old plug (#2) out when I was
changing for new and looked at it it didn't look as bad as before so at that
time I'm thinking maybe Chris is right. There was some carbon on the oil
ring and it's starting to blow itself out. When I pulled the new plug my
hopes were dashed at that theory. Go figure.

Well, you know when mine passes emissions, I then just like to go and
drive the thing and not worry about any repairs for another 2 years....

I've been thinking about this a bit and there is another thing I might
mention. You are getting oil on the plug for that cylinder, and it is
getting up into the threads. Remember, the threads don't seal the plug to
the head, the washer/seat on the plug does that. There is a small clearance
between the threads in the head and the threads on the plug by design. With
all the turbulence, pressure, heat, etc. in the combustion chamber, some oil
is going to work its way up the threads and stop at the sealing surface.
This is what is causing your plug threads to get oiled down. I still say you
should drive it for a while and see if it clears up. More and more I believe
this is a stuck oil ring on that piston and it may clear up with time.
Unfortunately, I don't like or trust oil and gas additives for cleaning out
engine deposits, so I don't know if anything like that would clear up a
stuck ring. Just keep the engine in tune, change the oil regularly or maybe
even a bit more frequent than usual for a few changes. Try and take the Jeep
on a few longer runs at highway speeds when you can. This may help free
things up and clear out the crud. This is all assuming that is the problem
of course.

I've been thinking about this a bit and there is another thing I might
mention. You are getting oil on the plug for that cylinder, and it is
getting up into the threads. Remember, the threads don't seal the plug to
the head, the washer/seat on the plug does that. There is a small clearance
between the threads in the head and the threads on the plug by design. With
all the turbulence, pressure, heat, etc. in the combustion chamber, some oil
is going to work its way up the threads and stop at the sealing surface.
This is what is causing your plug threads to get oiled down. I still say you
should drive it for a while and see if it clears up. More and more I believe
this is a stuck oil ring on that piston and it may clear up with time.
Unfortunately, I don't like or trust oil and gas additives for cleaning out
engine deposits, so I don't know if anything like that would clear up a
stuck ring. Just keep the engine in tune, change the oil regularly or maybe
even a bit more frequent than usual for a few changes. Try and take the Jeep
on a few longer runs at highway speeds when you can. This may help free
things up and clear out the crud. This is all assuming that is the problem
of course.

Thank you for your reply Chris.

Let me ask this. This (oil on the plug threads up to the base) is
inconsistent at best. That is, I have not been able to recreate the
scenario at will. The times this has happened is as follows:

1. Previous evening changed plugs. Next day drove about 10 miles with a
couple stops in between. On final stop took plug out to have a look.
Looked to be not bad. Replaced plug and went for a walk around flea marked
for about an hour to hour and a half. Looked at plug again and found the
oil on the threads situation.

2. Yesterday after smog test same effect only I didn't do the before/after,
only the after. Found oil on the threads up to the plug washer.


If it was the oil ring as the source, wouldn't it be consistent or at least
more consistent with oil on the threads?


My thoughts were that a single valve on this cylinder is causing the
problem. There is what, less than 25% chance that valve is open at shut
down (maybe even less)? Could it be this is the time when the oil is
leaking down from the valve guide into the cylinder at shut of but only when
that valve for that cylinder is open. Does this make sense?

The reasons I'm led in this direction is:

1. This happened after the engine was shut down and after the plug had been
pulled and replaced.
2. This effect is inconsistent.

Thanks for any agreements or contradictions to my theory to help me better
understand.
