This indicates that both #1 and #6 pistons are at TDC but #1 cylinder intake and exhaust valves are on the compression stroke and ready for adjustment while #6 cylinder is on the exhaust stroke. just when it's totally closed the intake valve will JUST start to open (commonly known as valve overlap). To get to the #1 cylinder valve adjustment bar the engine over and watch the valves at cylinder #6. So using the rocker method I usually start at #1 valve adjustment since the firing order on all inline 6 engines is 1 5 3 6 2 4. You could call these pairs sister cylinders.1 and 6 cylinder for example will have both pistons at TDC but one will be on the exhaust stroke while the other will be on the compression stroke. With an inline 6 diesel engine piston #1 and #6 rise and fall together in their respective cylinders as does pistons #2 and #5 and #3 and #4 pistons. ![]() The position of the engine will be at top dead center (TDC) and it depends on valve position that determines which cylinder is ready for adjustment. ![]() This procedure is called the rocker method that uses the intake and exhaust valve position as a reference while turning over the engine by hand. There is a way without having a manual to adjust the engine valves on any inline diesel engine because of the universal design that makes it easy to carry out this procedure.
