LD4B intake manifold coolant collecting

The only way coolant could be coming from that bolt is if it's coming from the gasket. That bolt goes usually exposed to oil in the galley from below the head, and needs to be sealed to keep oil from coming up the threads. Did you use a composite intake or steel shim intake gaskets?
