You know George I have the same problem with my 87, so let me know what kind
of job it is to get to the bottom of the prob. I can move the lever, and it
feels like it is moving something, however, there is no difference, simply
the TB type air coming out of the vents. -=dr=-

thanks - the old vacuum cleaner tube test tells me its coming from the
internal upper end around the pistons - not timing chain. Anyway, does
not
seem to hurt performance etc.
I'll try the look at the linkage on the heater - inside/outside air makes
little differance. Actually there is a little flow, kind of like a
terminal
TB case so I'm tearing into the blower to look for more debris after the
ice
is gone here in Arkansas.
If you hear anymore on available axle kits let me know

Hi George,
The ringing noise has me puzzled but I will take a shot at it
anyway, Piston slap comes from the cylinders having too much
clearance and the piston is rocking back and forth in the cylinder
until it warms up and they expand and get tighter, it makes a
knocking sound, the timing chain will make a clattering noise when
cold, carbon buildup won't cause piston slap but could cause
detonation or pinging but not at start up. Without hearing it my
guess would be more on the lines of a heat shield or exhaust shroud
vibrating until it warms up and expands. As far as the blower problem
the only 2 things that come to mind are either the inside/outside air
knob on the heater control is set to inside or recirculate or the
diverter cable from the heater control to the air flap has came loose
under the dash and not redirecting the air to the vents. Good luck
