I understand there may be an oiling problem. How does that make 1 & 6 have 30PSI? The issue is the actual PSI reading by the poster. The bit about "lack of oil" is the posters observation vs an actual gauge reading. Need to address the 30 lb reason before the oiling. Lack of oil will not stop the valves from operating mechanically. Some mechanical or gasket failure somewhere will. Find that. More inspection and testing is needed before tearing too much apart.
