Hi, Ted -
Remove the gauge and sensor line from the car.
Remove the chrome bezel and the glass from the front of the gauge.
Boil some water in a pot on the stove and insert the sensor tube. When the
water is stabilized at a boil, the gauge needle should be sitting between the
two tiny dots on the gauge face that represent 212-deg. Fahrenheit. If not,
carefully pull off the needle and reinstall it on the gauge so that it is
pointing between the two dots, and the gauge will be more or less calibrated.
The above assumes that the Bourdon tube inside the gauge has not been
overtemped and damaged (for example, by using heat to remove the sensor line
nut from the head), and that you live somewhere reasonably close to sea level.
If the Bourdon tube is damaged, you'll have to send the gauge to an instrument
shop for repair:
Mo-Ma, 1321 Second St NW, Albuquerque, NM 87102/Tel: (505) 766-6661
West Valley Instruments, 19314 Vanowen St., Reseda, CA 91335/Tel: (818)
.....And it would be a pleasure to add your '64 BJ8 to the other 5,687 BJ8s
now accounted for worldwide in the BJ8 Registry.

Subject: Temp/Oil Pressure Gauge Testing
Following a rebuild of the engine, the combo oil/temp guage on my 64 BJ8
does not appear to be operating. It is pinned at high temp. Can anyone provide
a process for testing and repairing this situation?
