ok, i have 4 lines on my crank pulley. there are three in a group and one to the right of the three. which line do i line up on my lower timing belt cover to adjust my timing to tdc?

 

you'll have a group of marks.. white redwhite then off bout a inch or to a white.. line the red mark up with the needle pointer on the timing belt cover thats should be top dead center compression stroke button everything up depend on what kinda motor you have you'll have to advance your timing to the proper timing spec's
