1998 v-6 626- Removed the intake today to change valve cover gaskets and saw a lot of radiator fluid between the heads in that little valley area. I have always had to be diligent about checking the water level since it was bought used at about 30,000 miles, it now has 110,000. Is this a common problem? There is a heater hose there that looks ok but I'll change it anyway, just wish I knew the problem before it is put back together. Any help appreciated, Charlie
