I have a 2003 Baja with 150,000 miles. I recently had an oxygen sensor replaced (actually there was another name for it but that is similar) and the mechanic said I had a small crack in a gasket on the drivers side and was leaking antifreeze. It is leaking outside the engine. I cannot afford this repair ($1000) at this time and the mechanic also mentioned there was a gasket on the other side...not yet leaking .
Have done some research on products similar to the one in my title. Anyone used them?
