Toyota Van 89 Engine Leak. on 1990 Toyota Corolla

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
My car is a Toyota Van 89. They don't have the year and model here so I selected the year and model above. But my problem is the coolant leaking in the cylinders and top of engine. I took the engine apart and replaced the head gasket, but that didn't fix the problem! The leaks goes through the last 2 cylinders (pistons 3 and 4).

To DaveJHM,

[quote]I'm wondering if you have an intake manifold leaking coolant. [/quote]
I suspected that too. Actually, I suspected the engine head. But Dad said it might be the gasket. So I replaced the gasket. I then replaced the engine head and the same thing happened - leaks in the cylinders. Mostly on the back of inside of engine.
