Re: Timing chain tightening technique...

Jim,

They all work more or less.

In my experience, ( I've learned to say that when posting anything on the
digest that fellow digesti or major digester de Matteo might read):

The most positive method is to leverage with a screwdriver like tool while
rotating (prefer the crank pulley nut but fourth or fifth gear works, too)
the engine.  This gives you visual and tactile confirmation of taking up all
the slack.  Of course, you loosen the lock nut before rotating and lock when
max extention of the tensioner is achieved.

Hope this helps, ]
Don
