1999 Cummins 53 block leaking
 

I have a 1999 Dodge ram 2500 with the 5.9l Cummins, 141k. Started noticing small amounts of coolant leaking under truck. The truck has the 53 block, went under and saw a 4inch horizontal crack on the passenger side just below the freeze plugs. Bought Bars Leaks head gasket fix, has anyone ever tried this stuff ? I bought the one that requires no draining, I know that eventually I am going to have to replace the block.
