how do I turn the crankshaft to access the torque converter bolts? Bentley
says to use adaptor 3052 with extension and T handle -- one of which I have

also,  there's a thing on my engine that isn't shown or mentioned in
Bentley, which obstructs the hole in the top of the transmission housing.
It's mounted on the black part of the intake air distributor, and has a
aprox 1cm dia metal tube going through the front cover plate;  it also has a
rod connecting it to the throttle assembly.  In the Bentley pic 38-394 on
page 37.4  it would show just above the woven tube part of the air
distributor.

any ideas please reply asap -- I've rented a tranny jack, but can't get
working because I can't turn the engine to get at the bolts.

thanks!
Alan
