All I have left to remove is the engine. Got to give the whole thing a good wash. Figured it would be easiest to get at it if everything else was out of the way. It was welded by the previous owner, but the way it looks, it failed too. I'm a welder and a fabricator for life. So this isn't something I can't do. I wondered how much damage was done to the inside of the heat exchanger and how much restriction it had with the weld job on it. Beings you can't see all that with the ****** weld on it now, I wanted to just get a different one and swap it.
