With Turbine:

Turbine multiblock broken:

I tested it some more and it seems like the turbine needs steam in it and there has to be a Machanical Pipe that gets rendered (seems like it doesn't matter if there is a Fluid in the Pipe) to break the block highlight

Edit:
Forge 1.10.2 - 12.18.1.2064
Mekansim 9.1.1.290

Fixed in dev, thanks!
