"About 2 weeks ago I was developing a slight leak at the tangent of the heat exchanger tank and the hose fitting. Having repaired this once before I was fortunate to not have to dis-assemble the unit and remove it from the engine bellhouse area to clean and solder the piece.
It was in such a spot I could easily heat it, clean, flux and solder it. I was so eager to just solder the fitting that I failed to remove the hose leading to the coolant recovery tank and the heat from the torch, slightly melted the hose. Later on ( 1 week later) when the engine was running it was allowing expanding anti-freeze to spill out of the neck thru the melted open hose. OH! SO THAT's why my port engine ran at 140 - 160 all day while the starboard NEVER moved off od 140 +/- 4 degrees.
As the low coolant level surged in an out of the exchanger and block, you could see the temps move 3/8" on the gauge.
DUMB !"
