My E-Type was recently converted to EFI. The car now starts and
runs quite well, except for running much hotter than it did pre-
conversion. One possible cause may be the prescribed pre-HE
distributor advance capsule (AAU6704) installed as part of the
conversion. It will not hold a vacuum. A low pressure bubble test
shows that air will seep from the hose connection side, through the
diaphragm into the opening for the actuator arm. It is difficult
to get any actuator movement at all when drawing suction by mouth.
Is this normal for this particular vacuum capsule?
Also, the advance capsule is connected directly to the rear port on
top of the right throttle body. It has a larger bore, and is more
centrally located over the disc than the front port is. At idle,
there is no detectable vacuum. Am I connected to the correct port?
Since the conversion, I have taken about 24 specific actions and
spent about half the cost of the conversion in attempts to control
the heat. The list of possible causes has to be getting shorter.
Thanks for any assistance!–
