Blue smoke -- Help!!
 

Hi all,
I previously had my jeep in the shop looking for the source of what I
thought was ping. The shop said it wasn't and that the noise was coming
from the valve train. At the same time he told me he could see blue smoke
coming from the tail pipe. I couldn't see what he was talking about and
left it at that. I took it to a second shop where they do dyno testing etc
on engines and he said I was chasing a ghost with the noise the other guy
said was from the valve train.

Last weekend I put my jeep through the first 4 wheel drive "romp". The area
was in a national forest and mostly used by trail riding bikes (in the
Cleveland national park by lake Elsinore, Ca). It was a good ride and I was
in 4 wheel low, climbing hills, going though water, and basically torquing
out the engine as I have not done before.

I noticed on the trail I can now see blue smoke coming from the tail pipe
and now, today, I can clearly see it coming out pretty well. It is most
evident when I let it idle for a time and then hit the gas pedal.

I just changed the oil before I left last weekend with a new filter and new
oil and I checked it today and the level is fine. There's no water in the
oil. It looks pristine.

I have smog coming up in the next month and I'm planning a major cross
country road trip.

Can anyone give me some ideas on how bad this might be and what tests I can
do to determine the status of my baby.

If it's the valves then I have another head (4.0L) that I can replace it
with sitting in the back yard. I don't want to do that though it it's the
rings or another issue.

Thanks,

Bill

Re: Blue smoke -- Help!!
 

how many miles are on this engine? what year is the engine? how much does
it smoke when you first start it?

bob z. is guessing that a new set of valve stem seals will fix you right up!

Not sure on the engine age/miles. I'm guessing from what I've been told
that I have between 60k to 80k but that's just a guess.

Do you need to pull the head to put the valve stem seals on?


Thanks,

In my limited experience if a vehicle smokes while idling or when it
is first started it is probably loose valve guides or worn valve
guides. I had a Ford Custom 500 when I was a kid and when it sat
overnight it would smoke like you wouldn't believe when first started,
it could also be rings but lets hope that it is valve guides.

It could also be a plugged PCV valve or hose.
