Water was leaking from intake manifold gasket. Mechanic replaced intake manifold gasket & thermostat. Picked up vehicle & broke down with knocking in the engine in less than 40 miles. Towed back to same shop & they said engine is no good now. What could have happened when they worked on my vehicle?

Thanks for the feedback. they did not change the oil. I drove the Jimmy 7 miles after it started leaking coolant(thats including driving it to the repair shop).
