Ok here is Missouri it is -6 out this morning. I go out to start my jeep and let it warm up a bit. It was a rough start likeit sound like it didnt want to start or taking its time anyway it sounded a lil different and then smoothed out. Stop to get gas down the street and noticed it was smoking looked under the jeep and seen drops of oil (I think) it drives and sounds fine but smoking bad. Pull back in to my drive way look under the jeep again and now there are oil spots all over the gravel. Did something crack or break from the cold?
