I got one of the block testers that detect combustion gases in the radiator. Everything is good. You were right about the moister in the exhaust part. I only have the exhaust done back to the mufflers. yesterday I finished one side. when I started it up, The side that was finished all of the way got some water out of the pipe, which looks normal to me. The side that was just back to the muffler yet, got the white exhaust (steam) out of it. So the exhaust not going all of the way back was kind of throwing me off to make things look not normal to me.
