Well, I'm very surprised! Those last 2 lifters are crunchy! I will, however, do as suggested! I think I'll give them a really good soak in penetrating oil before trying to rotate the engine. I'm assuming that I'll have to remove the rocker arm assembly to get the lifters and push rods out for inspection/cleaning vice whole head removal. Is that right? Please let me know if there are any things to avoid or specific things to do so I don't make things worse.... Nothing is too basic and I won't be offended by any advice! I'm learning this as I go!
