My m59 started sounding like valves slapping, especially under load at low rpm's. Kubota recommends valve adjustment at 800hr I think. We have a new kubota dealer here now so I scheduled with them. It's a very annoying noise. As I investigated I found the leaks. You can feel the leaks blowing out at idle. Will still go forward with valve adjustment and price them doing new gaskets too. Went ahead and started spraying pb blaster on nuts of manifold. Surprising they move pretty easy. So just an FYI.
