I did a valve clearance adjustment on a Caterpillar C7 inline 6 truck engine. Firing order is 153624. I thought I had the engine at TDC at the end of the exhaust stroke for cyl 1 to adjust 1I&E, 2I, 3E, 4I and 5E. I found out later that I had not turned the engine over enough, the engine was only half way through its exhaust stroke and I was off by 90 deg/quarter turn. Similar situation for the second half of the valve adjustment when I thought I had TDC for cyl 6.
Do I need to pull the valve cover off again and recheck? Engine sounds normal now with no clatter indicating excessive lash.
