i think that's what's happening. i heard something vague from the nice hippies i bought her from about one of the cylinder heads cracking and someone doing something short-term to fix it. about a month ago an odd, irregular tapping sound started coming from the engine whenever i revved, and about a week ago that went away and now she's very sluggish, shuddering at low revs and the engine is much quieter. maximum speed in third gear is about 40 MPH.
what i'd like to know is, how dangerous to the car is it to drive it in this state? i won't be able to afford to get her fixed for a few weeks.
