Derek,
The correct play is between .004" and .006". Note the extra 0. When the play
is excessive, you will feel it go thunk as you move the flywheel. If the
play was set too tight, after 80,000 miles it is now worn in. Leave it be
Dennis

Derek;
Good question. I also have experienced your dilemma. I think the
secret is not to flex the flywheel. Place the screw drivers at right
angles to the gauge. This way, in my mind, the flexing will be least at
the gauge.
My preferred method is to assemble the crank dry (out of the
engine i.e. on the work bench) with thrust bearing, shims, etc and torque
it down. Then see which is the largest feeler gauge that will fit
between the shims (this is your endplay). Do the math and swap shims if
neccesary.
Drive Safely & Good Luck
