Re: Ok guys, here we go. I pulled the head - take a look what I found
Looking at the stain on head 1.
The way it is running between 2 ad 3 is a gas oil mix stain, not oil.
Oil doesn't wick out in that kind of shape.
Cylinder 3 shows a wet piston.
Cylinder 4 shows the same piston seemingly dried out. Oil doesn't dry
up.
How does it look today?
If you had that much oil in a cylinder, you 'must' have had one massive
blue cloud of smoke following you.
I bet you still didn't swap injectors yet eh?

Re: Ok guys, here we go. I pulled the head - take a look what I found
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.
Thanks for any information.

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.
Thanks for any information.

Re: Ok guys, here we go. I pulled the head - take a look what I found
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.
