by rocker cover you mean valve cover, yes? And by tubes, you mean the PCV breather hose? If that is moving/popping, clean it out, as well as the PCV elbow and valve. It may be gunked up with emulsified oil. Once that is clean then evaluate engine performance. You can run a leakdown test to check valves and seals, as well as a compression test.
