My Beater car ( 1991 chevy Cavalier, 2.2L 4cyl, 5 speed, 109,000 miles ) has been leaking a little bit of anti freeze in my driveway, about the size of your hand over night, not alot. I looked under the hood while it was running and on the Drivers side on the front of the block there is a tiny spot where collant bubbles out once every 5-10 seconds. I havent noticed any antifreeze in the oil, or any other problems, I just want to fix this before somthing major happens. Does this sound like the headgasket is bad? I know these motors are known for that. How bad is it to replce a headgasket on these motors? Any Help is always appreciated, thanks guys.
