Pull the 2 plugs out of the flywheel cover. Then put a socket in the center hole, turn the crank w/ the socket till the T mark is lined up w/ the pointer in the small hole. On the cam gear there are 2 index marks. They need to be aligned horizontal w/ the top of the head. There is a timing indicator pointer on the other end of the crank. It should point straight up. That is it.
