Angry Coolant filling in one cylinder

Car ran thru a pool of water and one cylinder was filled with water thru intake and engine stalled, started normally after clearing the water. Now coolant is seeping into the cylinder regularly. How to fix this.

Type of vehicle? Year? Mileage? Engine size? Recent repairs? Condition of engine?

Sounds like a blown intake gasket, bad head gasket or cracked cylinder head or intake manifold.

Engine was probably damaged by driving it through the water. Water through the intake is not good. It can hydrolock the engine.

Cavalier 1994, 4 cylinder, 184,000 KM, engine condition prior to this incident fine, even now runs fine, but lots of white smoke comes. On starting one cylinder misfires, revvy up clears the plugs and engine runs smooth, but smokes, after shutdown same thing repeats. Removing plug and shows fresh coolant inside again.

Known vehicle with head gasket problems. Sure sounds like a blown gasket to me.

White smoke out of the tailpipe like that is a blown head gasket.

Thank you for your promt help. Would there be any chance that the cylinder head might be warped or cracked due to the thermal shock?

Sure. Good chance. It is an aluminum head.

Take the head off and take it to a good machine shop. They can check it for cracks and advise of any bad valves or other troubles.

You can then install a new gasket and rebuilt/repaired cylinder head.

Make sure you torque it to the proper specification (get a service manual before you do the repair or disassembly) and in the right order.

Post Cracked cylinder head

The cylinder head was removed and sent to a machine shop, where it was dicovered that it had cracked. (Thermal shock, eh!)

Replaced it and engine runs smoothly. Thanks for all the advise.

Common problem especially if it overheated at one time.

At least you found the trouble .
