Well if it is not to serious you can get away with driving it. But......your coming to cause more damage to the eengine if water continues to leak into the pistons. I have had this happen to me and eventually you will over heat the engine because you can'ttell the water level as you drive and wwon't know if the fluid level is full to keep the engine from overheating because it is sucking the antifreeze like a straw. Only thing Ican say for a temerary fix is the bars no leak that you pout into your radiator. Make sure you plug off the heater hoses. You ddon't want that to clogg up any cores in there.sometimes it will fix a small leak, but if it doesn't then the engine has majorissues


It's the intake manifold gaskets. The 3.8s are notorious for this. Usually between 90,000 and 120,000 miles. Have them changed and, as part of the repair, change the oil and oil filter twice to remove the contamination from the antifreeze. Do NOT use a stop leak product here. It will cause more problems!!
