I have 84 Eldo 54,000 miles, developed internal knock,:annoyed: sounded like pushrod out of holder, Upon removing valve covers, its evident one complete side of the upper valve train has had no oil in a while.The noise I believe was a dry lifter. The other side is oiling as should be. I can't find any info on how the oil is guided up to the individual sides (oil galleys) . I realize something has got to be stopped up, but don't really know where to start looking. My 84 GM manual does not show the oil distribution paths.. The pushrods are all clear and not bent. Any thought or ideas would be appreciated.
