How do I adjust my cam sprocket for chain stretch?

Do you have the wrong pulley/pointer, or is your damper torn and rotating? If the damper is ripped, you need to replace it right away. Not only can you not use a timing light, but you can break a crank. My race car damper ripped and was so bad that I could spin the fan with the engine off. Another member was kind enough to give me a good damper and I'm back in business.

I can't move it by hand at all, it's pretty stuck, and I've never seen it slip. it's just maybe 5 degrees off. it might be possible the previous owner had the wrong pulley, but it appears to work fine, and hasn't caused any performance problems, and the pointer is in the same spot every time I check the timing again.

Take a white or yellow paint pen and draw a line across both pulleys. That way, if they don't stay lined-up, you will know it slipped. I do this even on good dampers.

Job well done;)
