I'm doing a timing belt and set the crank to the mark and the front cam sprocket to the mark but the back cam shaft sprocket is not on the mark. The van was running before. Is this possible or did it move somehow?enter image description hereenter image description hereenter image description here

  • How far off is it? Is it not running now? The rear cam sprocket can move when the belt isn’t installed correctly. Installing the tensioner pulls the sprocket towards the firewall when there’s not enough slack on the tension side of the belt.

  • I’d set everything to the factory marks and make sure they still line up after spinning the engine. If you can, provide pictures of where the cam sprockets are in relation to the factory marks at tdc.
