I just tried to turn the engine/balancer pulley by turning the fan by hand but neither the crank nor the pulley wanted to budge. It seems like the balancer is intact but I'll have to remove the belt to check further.

I wish I had looked at it closely when everything was taken apart and out of the way.

As for pulling the engine and removing core plugs, etc to clean the water galleries, that's not really feasible at the moment although I understand that might be the only way to clean out a blockage if one exists.
