OK, I'm about to reveal my ignorance here so be it. Dave, you've made a couple references to rocker oiling and valve oiling. I get the basic idea of pressurized oil fed from the rocker shafts to lubricate the motion of the rockers. I see that manifested as oil flowing from the vent holes in the top of each rocker. As of now, all are oiling correctly in that way after I cleaned the vent holes. Is there some other kind of rocker oiling that I should be looking for? As for valve oiling, what would that look like if the valve seals are preventing oil from leaking down through the cap? Where else would the oil come from if not the top? Because I can't say from memory that I've seen oil on the valve stems. And if I did find a spring installed upside down, Carl, or I wanted to pull the valve oil seals out temporarily, Dave, how would I go about it without pulling the head and using a valve-spring compressor? I'd really like to understand these concepts.
