A couple of weeks ago I had to add 4 quarts of oil to my truck. I've never had to add any to it before. Four nights ago I was challenged by a small car that had V6 T on the side of his fender. The butthead didn't challenge me right away but waited until he could take a run at me from behind. What a sneak. My supercharger was whining like it has never whined before. When I backed off (because of traffic) it was running rough. It was hard to keep running at idle. The next day it was still running rough. When I left a stop sign taking it easy there was a cloud of smoke like I was spraying for mosquitos. It only lasted for a few seconds. About 2 blocks later, it blew out so much smoke I couldn't see the car behind me. It lasted a bout 5 seconds and quit. During this time I was a pint low on oil. Other than these 2 instances, it doesn't smoke. There are no oil spots in my garage. I haven't started it since. I checked the antifreeze and there is no oil. It has ran fine until I was challenged by that little six banger with the turbo. WTF, over? Any ideas what may be the cause of the rough running and clouds of white smoke. I welcome any suggestions or ideas.
