Leak December 08, 2009, 02:59:14 PM My motor 5.0 has 288K and is running fine, problem, I developed a water leak between the block and the timing chain cover, at this point I want to use a block sealer to stop the leak, maybe around 300K I will re build.Does anyone know what the best sealer is????????Lary Quote Selected
