The crank turns two times for every turn of the crank shaft, and each full
turn is exactly like any other......so if you did as I am guessing, turn the
crank through one complete turn, you are back where you were before. From
what I remember, the tool was clamped on the crankshaft pulley, and the dot
on the cam pulley was lined up on the "V".
Not sure what fixed it......but glad its finally fixed ....
Enjoy your trip to Colorado,
