So the saga continues.... 4140 Mitsubishi,
so here's all I've done so far.
Replaced the heat exchanger with a new unit, checked all houses to confirm they are in the proper locations, checked thermostat in hot water... it's 180° and didn't start to open until 190° fully open at 200°, replaced the heat exchanger cap from a 15 lb cap to a 20 lb cap, replaced the sea cock because it was not fully opening. Removed the thermostat to see if running it with out it would keep it cool.. Today was the 5th time I trucked it to the lake with high hope only to have it run up to 200° when running at 3/4 throttle, back off and it drops down to 140/150 range. I guess it's time to pull the exhaust manifold. You thought guys
