300x timing

hey guys i installed the new timming belt i made sure that everything was lined up meaning the cam's were aligned with the back plate and the timming belts white lines were aligned with the cams and back plate also.Anyways after i rotated the engine i noticed that the timming belts white lines wouldnt line up with the cams and back plate ANYMORE is that normal?Heres some pic's....also iT LOOKS like the crank should be moved one more tooth?Thanks

before i rotated it---------->



After i rotated the cam didnt line up with the whit line?i rotated the engine multiple times..


everything still lines up but without the timming belts white lines?






SHOULD THE CRANK BE TURNED ONE MORE TOOTH OR IS IT OKAY THIS PIC WAS TAKEN AT THE SAME TIME THE TWO PICS ONTOP OF THIS ONE WERE...WHEN I TURNED THE ENGINE I DIDNT FEEL ANYTHING HITTING AND COULD HEAR THE COMPRESSION IN EACH CYLINDER because the spark plugs are out thank you

You should be good man. Go by the lines when you put it on, and if it doesn't slip you are fine. Sometimes it is hard to judge by the marks on the backing plates and oil pump.

If you are really concerned about it, try counting the teeth. You will probably be counting for a long time because it is really difficult, but that will tell you for sure whether you are on point or not.

Then when you get everything back together, you can even try to compression test it if you are stillllll worried lol

I freaked out the first time I did this, in order to wear the timing belt evenly it will not line up again with the lines on the timing belt for quite a few revolutions. I think I tried 5+ and still didn't get it to line up, you can always go backwards if you are worried and want to see everything line up again.

It is most important that when you put it on the lines on the timing belt line up with the dots on the cam gears. The marks on the backing plates are just a general reference point and should not be used for the final belt install. They just get you in the ballpark.

As briggs said you can count teeth to make you sleep better at night

Hahah yeah i was freaking out too i did line up the cams and the crank with the timming belt lines so hopefully its all good... im going to do soome research to count the teeth on the belt just to make sure because im still worried lol

The counting of the cogs between drivers exhaust cam pulley and crank pully is a PITA!!! Just take your time and maybe use some way to mark the side where you start and end and maybe every tenth one, definitely helped things along.

ahha thanks for the advice i already counted and it looks good but im going to do it your way (nissanfreak12) just to make sure ahha:) Thanks for you help!!!
