The lab noted high levels of sodium (PPM=91) in the sample and concluded a RW leak from that. The engine is FW cooled. The heat exchanger was pulled, flushed and put back on by one of the better mechanics in Palm Beach. There was no white smoke. Had a LOT of black smoke when we put the throttle to the stops (@2,800 rpms) briefly (injectors need service, probably). The engine has sat for about three years prior to the work being done on her. I didn't check the coolant level in the heat exchanger after the sea trial.
