I have a coolant leak at a crack in the intake manifold at the top-front of the 4.2(maybe 4.6?)Liter engine. The leak stopped when I put in a stopleak "mud" and held through the winter. Then it leaked after a 3500 mile trip coating the engine with a fine-coating of fine mud/dust. (I have a competent mechanic for whom I had the engine compartment pressure washed ... the motor is clean like new. The engine runs good.) What will it cost to flush the coolant and mud, then replace the intake manifold and refill coolant?
