Left my '01 4.4 outside my warm garage (mistake) so we could have a new years party. started it up at -5 F and drove it about 5 miles realized I was one of those idiots leaving a giant smoke screen behind me. I usually laugh at those people cuz they dont know something is wrong.
my X has 113K on it, bought with 100K. After I had my wife pull me home with my trusty steed Yukon I pulled the oil seperator out, blew it out and there appears to be all new hoses, new osv and has an electric warming blanket around the hoses. It appears that the extra winter kit doesnt help all that much. I took the throttle body off and stuck some rags down in the intake and got a lot of milky oil out of there.
after running it for half hour it appears cleared up, must have been lots of oil in the exhaust. I ran it for 5 minutes the first time and took throttle body off to check for more oil, which there was a little, but not much. Decided to run it longer the second time and checked again. Looked good after that check.
I dont get it, do I have to drive something else when it gets really cold out. My wife had parked it after a one hour drive, shouldnt have been a big problem with condensation.
I thought some of you might be interested to know that the extra money spent on the cold weather parts dont really seem to completely fix the problem, although they may help, who knows.
The X normally gets drive 25 minutes to and from work on a very regular basis. If it wasnt so awesome in snow, which we have a lot of, I would get rid of it. I called the local dealer and spoke with a tech who was very helpful, he said if all those parts look new to just blow it out and reuse it.
In the 6 months I have had it I was stranded by an alternator (trans fail safe warned me a couple times), tailight problems, display issues on radio, now the OSV. Its going to be a long winter.
Thanks to this site I am able to figure these issues out. Fantastic information on here and I dont know what I would do without it.
