dead SPI engine, need to find the problem

My focus was running rough and pepboys recommend to replace all three engine mount. I prepare to DIY it. After I received them from Ebay, the engine light is on showing the fourth cylinder misfire P0304.

And after two days, there's loud noise when start and then the engine dead after several try. I found the spark plug is broke in the fourth cylinder which filled with coolant. Is that the same problem with the valve? thanks.

As a new member, I don't know why the coolant can enter the cylinder.

I just received the engine hoist today. I'm happy to join the dead SPI engine club.

Add yourself to the list of a dropped valve seat in #4, pull the head off, the light end of it you need a new head as yours was smashed up allowing coolant to come into the cyl from the head, worst case is you need a new block as its cracked. Wont know till you remove the head. I have good used pistons and rods if you dont need a block. Likely all your pistons will have damage which in return bent your rods.
