Give us the details and I sure that we can help point you in the correct direction.
Just the bearing, piston and rings were replaced on that cylinder. The cylinder was lightly scuffed honed to break the glaze.

NO way could coolant have gotten in that cylinder!
So,,,,I pulled off the intake manifold and this is what I found:

The HEAD had a defect in the intake runner. SURPRISE!!
Both valves were shut so it pooled up in the runner. Dont ruel out coolant!
Point being taken, I thought the same thing that you did. Fuel Injector!
Pull the fuel rail off the intake, point it to the sky (do your self a favor and put a rag over the injectors) and turn on the ignition. If you have a bad injector, it will spray fuel everywhere. (Take all fuel safety precautions and have a extingusher handy!!)
If you have a leakey injector, it will drip fuel!
