Today I was on my way to class which is in Lansing, about an hour drive. 20 minutes or so and I start to hear whistling sound or even whine from the front of the car, to my right side. Sound gets louder and within 5 seconds a small bang or explosion under the hood. The engin gradually loses power to the point where I almost have to keep the pedal to the floor to keep the car moving at a decent speed. At this point I see a little debris in my rear view. Engine is dogging and struggling but it is at a steady speed. I drive a mile or even 2 to the next exit (car was acting well enough to make it that far.) I make it up the offramp and begin to shift from 5th to 4th. As soon as I take it out of 5th the RPMs hit 0. red lights across the board and I coast in neutral to the light. Pull off to the side and put on the flashers. Now, I try starting the car again but it just will not turn over. I get out and open the hood and there is white (not dark or black) smoke, coming from or around the alternator, possibly below or fromt he engine (It was windy) I ran across the street and had a friend come help me push it across the street to gas station parking lot. Once there I tried once again to start it. It started up but only for a few secinds until it stalled. During those few seconds it sounded as if timing was off or not running on all 4 cyl. I did not notice any oil leaks or missing belts. I honestly did not look at it too much. Recently (within the past week) the oil light would blink or flash for a second. I realise and admit I need to change oil more often.
