smd4 posted:In that pacing shot, steam is leaking out from under the jacket covering the cylinder. Weird.
So here is the official word from the Engineer in the pacing clip:
" There are exhaust cavity drains in the bottom of the cylinder block. They are open to the air and drain out condensation (water) that will form when the engine is cold"
"On 475 the right rear cylinder head is leaking (about the 3 o'clock position). Piston rod packing leaks slightly on both engines. Not sure about the cylinder cocks. If it is coming out from under the cylinder block and is more of a cloud and not much force, then it is coming from the exhaust cavity drains as some exhaust steam will escape through them"
