negative! each cylinder, including #1, travels thru TDC twice on a 4 stroke internal combustion engine. That means the crank spins two complete revolutions for every cycle of stroke events. So in short, when the timing mark on the dampener lines up with the timing mark on the timing cover it could happen at two distinctly different times, TDC on the compression stroke OR TDC on the exhaust stroke. Not to confuse you more, but that also happens on #6 cylinder only it's vice versa from whatever stroke #1 is on.
