" From: JOE FULTON <piper_pa20@xxxxxxxxxxx> " " [] " A few days later, after sitting I " restarted it and it had no oil circulation to the head " and the dry valves clattered. I connected a " mechanical oil pressure gauge to the engine and it had " 50 pounds of oil pressure with the oil cold, but still " no oil to the head. Then later it had good " circulation to the head again. Something is " periodically blocking circulation to the head. Yes, I " pulled the shaft rocker bolt and the suspect head bolt " and tried to clean out the passage. I also used engine " flush. second thought: something could be allowing the oil to completely drain back, so that the galleries are empty after sitting a few days. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
