Tming belt sprockets mark wont align.

From : leviathan

Q: im trying to install the timing belts on my car. the book says to align all the marks and turn the crankshaft 720* and the marks should align once again. i aligned all 4 marks and i turned the crank 2 full rotations and something is always off. does anyone have any idea why this is happens thanks. .

i mustve tried putting the belt on and taking it off at least 10 times. it was like this 1- the left silent shaft cam and crank align but the right silent shaft oil pump sprocket is off. or 2- as i keep turning the crank i can align the right silent shaft left silent shaft and crank but the cam is off exactly 180*. .
