Coolant in cylinder 8 on 318

This could be something simple as, while it was being disassemble after the bench testing maybe some antifreeze could have spilled into the intake. Such as the upper coolant hose, which can hold a fair amount of antifreeze on a hurried removal.

It was pressure tested on the bench, not run tested. They never even installed a water pump. They have a machine that will turn the crank and read cylinder pressures etc. There definitely was no liquid anywhere in this block except assembly lube until I dropped it in.
