I was checking out my 540 with a cheap bore scope. Cylinders all look good and I'm rotating the engine on a stand with about 12 quarts of oil in it. But I found rust in this cross bar inside the front propeller oil shaft (I think, I don't know what it's called) and now I'm worried. I think this supplies oil to the shaft but again I'm not sure. Is this something to worry about, aside from fogging it and finding the darn cap is there anything I should do?
