If its just on start up, its probably condensation coming out the exhaust. If its all the time then its probably a blown head gasket.

White smoke could mean that you are burning oil or coolant for some reason. Coolant would be a bad head gasket

With suspicious smoke, there's also the need to look at the overflow of the coolant resevoir & assess if it has lost fluid. Mark the level when cold & on level ground. Check again in a week or so, park in same spot, draw a new line.

There's also a test to see if there are disolved exhaust gasses in the coolant. Most garages use them these days. http://www.ehow.com/video_12213890_c...ntifreeze.html

Typically, blue smoke is oil and white smoke is coolant. Like Double E said above, take it to a shop and they can tell right away with that little doohickey that will sniff for hydro carbons in your coolant.

Having the same problem. It just started. White smoke, no smell and it looks like something was spraying out because there are little liquid spots on the back of the Jeep. The engine was bucking a little however it subsides when the air conditioner is cut off. At slower speeds no smoke comes out. What could be the problem?

Wj same issue

my 4.7 is doing the same things...intermitten...no change in coolant level, no leaks, no loss in power...

i have a tiny tiny oil leak (no traces on the ground just slow drop in oil levels over weeks).... but the smoke is white....

i need a new cat.....but doubt that has anything to do with it...

White smoke is pretty common for these 4.7 engines imho.

agree

however need to ask
is it white smoke or just a lot of vapour, and water coming out the exhaust??
if its gasket then there will also be a drop in water lever for a start
my one has been doint that for a long time, its just condensation
specially if it has no smell

a unrestricted exhasust will make it even worst, for those who know what I mean!!

Tj white smoke out of exhaustt

I have a 98 TJ that is blowing white smoke with fumes and makes an awful squealing under the hood. I have replaced the oil pan gasket and it is not hesitating any more but still blowing smoke. Any ideas?
