update. i tightened the filter as much as i could with a wrench. solved the oring problem, but i still have a pressure problem. its holding seventy pounds at idle after the engine reaches operating temp ( about 50 more than normal) and if i give it any throttle it pegs the gage. back to the missing for now. i removed the valve cover and started the engine. the very front rocker isnt rocking. i pressed down it over the pushrod is moving but the rocker has to much slack to open the valve. i watched all the rockers and noticed that some of them travel more than others. what can it be?
