recently the fuel pump diaphragm was leaking fuel into the engine oil. by the time I detected/responded it had washed the interior of the untouched engine in my 52 with the 216 cu with 100k miles. on oil change I noticed a lot of sludge draining. on driving I also noticed better oil pressure and a somewhat quieter engine. tinkering around under the valve cover and with the engine at idle I noticed little to none oiling to the rocker arms. now I'm am concerned about interior passages as well. any thoughts on where to start on the rocker oiling and is my concerns valid. less than a 100 miles on engine since oil change.
