I don't know what to tell you. I understand your disappointment putting a new engine in it only to find another unexpected issue.
When the rod broke, you were using it, I presume cutting grass? How did you get it into the garage if you didn't tow it? How did you do that?
You had the rear wheels on jack stands to adjust the neutral. That worked with no noise, correct? Then when you put it on the ground, it made noises? did you ever attempt to drive it despite the noise? Could it just be hydro whine?
