Thanks=C2=A0 for all the ideas about this...
Mleccese - the car has a rubber seal on the crank and double seals on the t=
rans...nice and dry in there, no oil leaks.
Tony - the car has a Tilton 7.25" setup with the "copper" colored=C2=A0full=
 circumference disc (not individual "pucks") with a Tilton aluminum flywhee=
l.
Marcel - the metal clutch line was not changed, but it wasn't kinked anywhe=
re and I could blow thru it ok. The clutch feels as it always has just has =
this "instant" on/off that the driver cannot modulate.
David - the slave rod was in the center hole, but it worked the same when i=
n the lower hole.The flywheel looks perfect and there is no measureable "be=
ll" to it, no heat cracks or burrs.
Phil - the first "repair" was the disc, throwout sleeve. trans input shaft =
and diff change. The "full Monte" of changes have not been on track yet, bu=
t nothing that was replaced has been out of spec anywhere. The car has the =
steel throwout bearing flange and was pinned as it just doesn't seem rite t=
o let steel on steel rotate. The pin was moved 90 degrees from where it was=
 in case there was any unseeable wear from the fork on the sleeve.
Mike - Doubtful that anything "downstream" of the clutch is the problem. Th=
e trans was disassembled and the input shaft was changed after the first ty=
me. The driveshaft was inspected and rebalanced and the diff was changed to=
 one that has been faultless for years, still had the problem.
The only other thing that has been changed is the clutch master diameter...=
went one size smaller as I thought that might give the driver a bit better =
chance to "modulate" the pedal. The interface twixt the throwout bearing an=
d the throwout bearing flange has been relieved in case it may have gotten =
hung up somehow on the sleeve. The clearance twixt sleeve and throwout bear=
ing flange is also within specs and moves easily by hand.
I'm about out of ideas here at this point and I have no confidence that any=
 of these changes will affect the issue. It sure seems like I'm missing som=
ething here!
