Default burning oil? losing oil?

i noticed within the last couple months ive prob added almost a qt and a 1/2. i check it randomly and when i do i add till its safe on the dipstick. i noticed today af ter the carwash that eventhough she was warmed up to perating temp, the exhaust still was smokey at idle(like she was still cold). it is around 25 out.. im wondering if im burning oil? what should i start looking at? she has 108.5k on her.

try running some seafoam through your engine to clean it all out, then when you do an oil change, use some engine restore and some MMO along with your oil.

Paro, you said it was smoking like it's cold when it was warm. Was the smoke you were seeing blue or black? If you're engine is burning oil, you will see blue smoke. If it is running rich (Too much fuel) you will see black smoke...and of course white or gray smoke is normal when cold.

At 108K it is quite normal for your jeep to burn a little oil. 1.5 qts over a period of a couple of months really isn't all that bad. Does your engine run fine besides the smoke you are seeing? If it is I would just add as it needs it. At your next oil change I would use one of the oil additives the other guys mentioned. Mike's Mystery Oil, Restore, Slick 50 are all additives I've heard good things about.
I would also recommend that you do a compression check on all of your cylinders. If they are above 100 and are all pretty close to the same PSI, I'd call your motor good.

smoke is not blue or black... white like its cold. smokes alot though when its cold. am i leaking oil? it doesnt leave any spots anywhere. she runs fine, i ran seafoam through her the day i got her- the throttle body and gas tank and she smoked for awhile... like the smoke never cleared up- took a week or so to get it to clear up. so maybe it was alot of carbon build up. i have some engine restore im thinking of running- although i think im due for an oil change in the next 500. so i may hold off on it. just strikes me as odd, burns my oil than my supposed "oil burner" ctd. lol.

Uh oh, I just had another bad thought. white or gray smoke when the motor is at normal operating temperature is also a sign of water being burned in the cylinders as in...I hate to even say it....a bad head gasket. That would also explain your oil disappearing on you. Pull your radiator cap and check for an oil slick on top of the coolant. I hope I am wrong in this case.

hmmm ill have to check that. wouldnta blown head gasket lead to high operating temps? also wouldnt the oil be milky looking? i just pulled my dipstick last sunday and it needed oil, but wasnt milk and looked normal in color.

Yeah it would have a higher op temp most of the time. How cold is it? 25 for a high? Of course we havent touched on the fact of "loosing oil". Have you done an inspection of the motor and surrounding areas? Is there any oil drips under the jeep?

if your smoke isnt a pure white or bluish, then its probably just leaking off somewhere. at idle i smoke pretty blue, its either totally gone valve stem seals or the rings are done. i'm going through a quart every two weeks now......

time for a motor.

It just smokes white a lot... So I take it I have a leak somewhere- my guess is the rear of the head gasket. I'd say the rear main seal, but I can't see that dripping onto the exhaust and causing smoke. I checked my antifreeze, no oil or film on top. Stirred it up alittle, nothing in there.

Well, the good news is that the blown head gasket theory is out.
