engine running with the valve cover off, adjusting the valves. an annual event, it takes 20 minutes.
because the engine is slanted slightly rearwards, oil runs down the rocker shaft and drips on the back edge of the valve cover. perfectly normal, but it tends to accentuate any tendency for the valve cover to leak. the second video shows the result of a simple (and crude) fix that eliminates it. that piece of wire has been there for a decade.
more of the same.
