I have fixed manyof these cars for this problem. Under the plastic intake is a tube that has exhaust gases running thru it. This is part of your EGR system. Now this tube gets so hot it starts to melt the intake around the tube. Real close to this opening is a collant passage. Once the tube melts enough it allows the coolant into the engine and floods the engine with coolant.

I have yet to have one that couldn't be saved. SAimplly replace the intake and spark plugs. Make sure while the plugs are out crank the engine over to get all the coolant out of the cylinders or you can bend some of the valves and ruin the pistons.
