G'day all, I would be more inclined to believe that you have a sticky valve or valves. I have encountered these on some of my Packards over the years and they can be quite common on the 282 motors. I would discount broken rings/ piston problems unless you are suddenly blowing lots of smoke or have developed blow by symptoms in the sump. I would recommend using a strong light and inspecting the exhaust valve stems of cyls 5 to 8, with the valves closed, for evidence of galling on the stem or carbon. A compression test would be handy but probably inconclusive if the engine hasn't had a valve grind in the previous few thousand miles. Good luck .. Peter
