Okay, think I have problem resolved. I poured a bunch of Marven's Mystery oil into one of the removed rocker arm shafts. After a few pours, I would turn the engine on to see any results and after about the third time, oil appeared to be coming out of the small holes. I could tell I was on a good path since I could see the Mystery oil pouring from various minute crevices and even from the top after a few pours, so I knew things were clearing up. When the engine was running, the oil coming out was like little rain drops of oil spraying from the holes. I will try again later to see if I get similar results. I am waiting on new injectors to finally wrap it all up.
