If you're (eg) setting the valve clearences or something which requires
turning the engine manually, should you turn it the same way or the
opposite way to its normal direction of rotation?
My engine turns anticlockwise looking at the flywheel end, but haynes
says to turn it clockwise *and never anticlockwise* when turning by
hand, but I have something in the back of my head that engine bearings
only like turning one way, am I wrong?
