I spent most of yesterday stripping down and cleaning the gunk off the engine. The intake manifold appeared to be the worst offender for oil leaks, it was caked at each corner and appeared to be leaking from a poor silicone application.
I wasn’t able to get any pictures of the process, but my neighbor brought over his JD tractor with forks, and we lifted the cab off the new frame.
I also picked up some valve cover gaskets and an intake manifold gasket kit.
