I discovered the source of my cars recent problems this weekend. I'm not sure which side it is, but I'm 90% sure I have a leaking head gasket. So is this K&W stuff any good or should I avoid it? I don't want to make my problem any worse than it is as the car is still very driveable right now. The car has to get me through about another two months before I can get it back home and fix it properly. Any input would appreciated.
