Sorry Dusty, it's bad. I think you'll find that the head gasket(s) has failed, which is bad enough, but with oil in the coolant it means that there is also coolant in the oil. Modern antifreeze destroys the bearings in the motor in a short time. The motor is likely toast.

You can try some head gasket sealer, there's a lot of it marketed, but once a gasket gets as bad as yours is it's very unlikely that it will work.

I need to know how to tell if i have a blown head \head gasket


If you car is overheating often and white smoke come out the tail pipe when running, good chance it is. Easiest way it to check is the fluid in the radiator - look for oil floating on the top. If your cooling reservoir (off white container connected by a smaller black hose to the radiator) has fluid in it, check it or you can open the radiator cap (only when the engine is cool - hasn't been running - don't touch it until it's sat for a few hours if you used it) and use a turkey baster or similar to pull some fluid out. If you see some oil floating, it's most likely a head gasket.

I have a 2002 4.7 jeep grand cherokee limited. It has a miss. Smokes but no code. White smoke. Oil looks perfect on dipstick. No bubbles in coolant at radiator.


Water in the gasoline, or a leaking head gasket. A leaking gasket may not show water foaming or discoloration in the oil, but level in the radiator will go down over time.

Limited. Why would it be smoking after replacing one plug?


what smokes. we are blind here.
you must stay.

1: end of tail pipe smokes
2: or, with hood up the exhaust manifold smokes due to oil we dropped there. (common on much service)
and what color is it.?
from where.?
tail pipe can do 3 colors
white goes away fast ,called steam.
white stays way too long called burned oil smoke,
and black (unburned fuel) and smells like gas..

1990 Geo metro popped and poured white smoke out


its a GEO POPPER.
"no oil up on crank case"

no idea what that means.??????
yes PCV valve. do clog.

white smoke at end if tail pipe.
you didnt say where,?

white smoke has 2 reasons.(tail end)
Steam and oil.
steam goes away fast and looks just like moms tea pot. and smells sweet, like the antifreeze in engine. (rad cap off ,sniff sniff, cold engine)

oil burning, smoke is very very slow to go away.
and smells like , blush burned oil.
if not sure what burn oil looks like or smells like
take out the dip stick on a hot engine
let it drip to the hot exhaust manifold there.
now you know. and is a key diagnostic skill.


no oil seen on dip stick end?, you mean that?
well you need to keep that from happening,
doing weekly service, and for sure old cars.
26 years old.

low oil invites blowing up a good engine.
for sure.
if it did that smoke is oil
if it did 10x worse, both .

my wild guess is you meant to say
I didnt see oil leaking on top of engine.
right?

if the engine backwires to the air cleaner
you forgot to replace the cam belt every 60k miles
the pcv will also be clogged, on cars not getting proper service, super colon.
if the PCV clogs,engine may leak oil bad.

this engine btw is a G10 3 cylinder.
with TBI injection.
we can talk TBI all day, owned one.

white smoke can come from many places
exhaust manifold, leaks of oil can land there
engine can back fire to air cleaner making smoke.
tail end.
steam is much worse. ill not delve in to that yet/.

White smoke


from where, end of tail pipe or ?????????????
tail smoke has 2 types,. oil and steam.
1: steam smells sweet(glycol) and goes away fast.
2: oil smoke, smells like burnt oil and takes a vary long time to go byebye.

or is normal.
all cars burning gasoline make water (H2O) as a byproduct, of combustion the seems to go away on a hot day.
but really does not, it just seems to.
on a cold day all cars make steam
if yours is and your neighbors car dont at the SAME time (out door temps same) then your steam is wrong. a bad sign of bad head gasket or far far worse , a cracked head.
did you do the pre fall service, and check antifreeze protection levels.
a $2 tool that save cracked engine blocks.

After changing thermosat car is now smoking a lillte from the driver side radiator area


Smoking where.? tail pipe end.?
over heats, when, moving at 60mph
or only stopped.?
if that smoke is during a hot running motor, and is steam
the head gasket blew (or worse)
oil smoke burnt lingers a long time, steam goes away fast like tea pot.
smoke smells like burned oil, steam smells disgusting sweet due to
the coolant is 1/2 Glycol.
over heating has many reasons.
only stopped?, bad rad, bad pump, bad stat, bad fan clutch.(or elect fan)
fails to over heat moving, usually is bad fan (action)
steam at tail is coolant burning.

I think my car blew its head gasket,but theirs no water in oil,if idling temperature stay normal,fans do come on when idling for long.I`ve changed spark plugs,plug wires,thermostat and heat sensor unit.As...


white smoke from the exhaust and overheating would almost certainly mean a blown head gasket.
the head gasket has gone between a cylinder and a cooling channel so exhaust gasses can get in to the cooling system resulting in the boiling and water from the cooling system is getting into the cylinder resulting in the white smoke (actually steam) from the exhaust.
the exhaust manifold is a separate issue that can be replaced when the head gasket is repaired.

Smoking, ideling rough,


Hi: What Color is the Oil coming out of your Tail Pipe? I'm Assuming its Motor oil and not Transmission Oil.Since you found white looking substance in your oil It sounds like you have a Blown Head Gasket or both.And could be a Crank Block or Head ,Pull your Spark Plugs out, And Have someone Crank engine over and see if you are getting that white Substance Which i assume is Motor Oil.If you are getting ANY out of ANY Spark Plug hole then Is fair To Say you have a Blown Or Cracked Head Gasket.THERES only 1 Other Alternative On Older Vehicles than Yours is ,They Had what was Called a Vacum Modulator That Attached to the Auto Transmission, I worked off of Vacum From The Intake Manifold,And if the Diafram in It went Bad it would **** Transmission Fluid up Through the Intake Manifold and Burn It through your Intake and would come out tail Pipe as a WHITE SMOKE,But it normally would not be in the Enging Oil Or Radiator.So i Would 1st Check the 1st Advise i have Given You.Pull The Spark Plugs. Hope This Helps.Please REply by Voting if this Helped Youat All,Thanks From the WYOCWBOY
