Thanks Patrick for a scientific answer. At the moment I'm not worried as I haven't overhauled the motor yet. It's still the donor engine. I think as long as you let the engine get hot it should evaporate out most moisture, opposed to starting it up for 1 minute and building more condensation in the engine and exhaust. I remember a customer come over for a service and only drove it 2 miles to my workshop. He complained of always rusting out his mufflers. I drill a small hole in his new muffler at the lowest point and removed a cup of water out of it. The hole was small enough not to hear the exhaust leak, and his mufflers lasted a lot longer. JD
