Also, I notice before I put the cover on after I torqued the cam bolt, I turned the engine over with the ratchet, and it feels like the chain was skipping, it was not smooth, like it was not gripping and then after a few turns it was smooth and fine. I looked at the chain and all the teeth are on the gears. The marks are still lined up correctly. I don't know what happened? Or why it did that? Is that normal?
