I tackled the repair of a chronic coolant leak in my truck today, thinking it was leaking from freeze plugs under the manifold. I discovered a crack in the outer water jacket of the block about where the cylinder block merges into the crankcase skirt. It is in a place that is pretty accessible in the vehicle and can be ground out, drilled for holes to prevent crack propagation as well as allowing for moderate preheat without affecting other parts of the engine.
All else being equal, what process would have best chance of success - nickel rod, braze or CI filler rod? I have done all three in the past (not on installed engines) but don't currently have any equipment so I will have to hire somebody with the talent.
This is in a Dodge 225 CI slant six, other wise a good runner for my purposes and one I want to keep for a long while. The only cause I can determine for the crack is freezing but I certainly don't know when it might have occured.
I'm thinking I have little to lose by trying a repair.....if it doesn't work I can get another engine but that's a lot more work and money.
Any thoughts are welcome.
