Well, I still need to get the hydrovac hung up, but I got the fuel system hooked up and actually drove it around the farm for the first time!
I think I lucked out on the motor, as it idles smoothly, has no major leaks, and does not seem to blow any blue smoke that would be indicative of oil burning. I did have to pull the manifold to replace the gaskets and had to replace the exhaust manifold because of a huge crack. I managed to find a replacement locally. I also had to change out the oil lines going to the oil filter.
We got our first big dump of snow this week, so I'm going to ramp down the work until springtime. I have some frame crossmember repairs to do, and I also plan to take the transmission off so it can be re-sealed. It is a huge ball of grease!
