it would be neglect of the oil changes somewhere along the line i believe.

actually a very worn cam can affect the compression test. if the cam doesnt hold the valve open long enough it can prevent the cylinder from drawing a full cylinder of air, thus giving a false low reading. false in the sense that the valves and rings may be fine.
