last night after driving my car(97cobra) to a friend's house i noticed a burning oil smell which only got worse on the way home, just before i got home i could see smoke coming from under the hood. i had it on the high side of the power band pretty frequently last night, but i've never seen this before. i just changed the oil with motorcraft oil and filter less than a thousnad miles ago. does anyone have any experience with this problem? any help is greatly appreciated, thanks in advance.
