If a cylinder or engine runs flooded, the gas washes the oil and carbon
build up out and it makes a messy stain like the photos show.

It washes the cylinders down and allows oil to mix with it and get past
the rings.

The stuff is almost oil like and almost varnish like and it makes a
wicking stain. It is also a lot thinner than oil to the touch.

Oh, now that it is apart, can you get a visual on the nose of the
injector from #2 and one from another port to compare?

Interesting, Mike.

I do not see #3 as being "wet" and #4 being "dry". They look pretty close
to me. In fact. #3 through #6 all look pretty close.

Now, #1 does look wetter than numbers 3 through 6. Is it possible you mean
this one?

I did run a can of BG 44K though the engine before I pulled the head so
perhaps this made the effect on the other cylinders.

I did not have a big blue cloud following me. The only time I noticed it
clearly was at the smog station.

No, I didn't change the injector which I can see now is not that hard to do
(have to pull the rail) but will keep that in mind for when I get everything
back together.


This is what I'm going to do.

1. Take the head to a machine shop today to see if he can find anything
wrong with or around #2.
2. If he can't find anything wrong with it I'm going to pull the piston from
that cylinder and inspect/change the ring(s).
3. I'm going to put the 4.0L head on instead of the 4.2L.
4. Change the injector to another cylinder far removed from #2 (maybe #4 or
#5).

If everything goes well I should be done by this weekend so we'll see what
happens then.


Some questions I have.
1. What's the best way to prepare the block for the new head? How to clean
it up, etc?

2. I didn't feel any lip at the top of the cylinder that would call for a
reamer but there is carbon crusted there. How should I take that off?
Should I get the reamer anyway?

3. Regarding the push rods and the new head. What should I do in this
situation since the head is totally different and therefore cannot match up
"worn" parts.

4. Can I or Should I replace only one ring (oil) or should they all be
replaced.

Thanks for any information.

Bill
