Turning engine over by hand?

[v_balge]

I'm getting ready to replace the valve stem seals on my 280z with the head still on the car method. The descriptions I've read say to turn the engine over by hand. Whats the best way to do this? Is it safe to use the cam shaft sprocket?

Normally you'd just use a longer breaker bar with a socket on the crankshaft pulley bolt. You can do this without even taking the valve cover off. I'd do that instead of trying the camshaft idea. I think it's a 27mm bolt.

Yep, 27mm socket is the one for the crankshaft. Rotate in direction of normal engine operation.
